ObjectiveThere is paucity of data on the durability of physician modified endografts (PMEGs) for complex abdominal (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs) despite widespread use. The aim of this study was to evaluate and compare the early and long-term outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) for CAAAs and TAAAs using PMEGs.MethodsWe reviewed clinical data and outcomes of patients treated by FB-EVAR using PMEGs for CAAAs (defined as short-neck infrarenal, juxtarenal, and pararenal AAAs) and TAAAs between 2007 and 2019. All patients were treated by a dedicated team with extensive manufactured device experience. Endpoints included 30-day mortality and major adverse events, patient survival and freedom from aortic-related mortality (ARM), freedom from secondary intervention, target artery (TA) patency, and freedom from TA endoleak and TA instability.ResultsOf 645 patients undergoing FB-EVAR, 156 patients (24%) treated with PMEG (121 males; mean age, 75 ± 8 years) were included. There were 89 CAAAs, 33 extent IV TAAAs and 34 extent I to III TAAAs. A total of 452 renal-mesenteric targets (3.1 ± 1.0 vessels/patient) were incorporated. Patients with TAAAs had significantly (P < .05) larger aneurysms (73 ± 11 vs 68 ± 14 mm), more TAs incorporated (3.4 ± 0.9 vs 2.8 ± 1.0), and more often had previous aortic repair (54% vs 27%). Technical success was higher in patients treated for CAAAs (99% vs 91%; P = .04). Thirty-day and/or in-hospital mortality was 5.7% and was significantly lower for CAAAs compared with TAAAs (2% vs 10%; P = .04), with three of nine early mortalities (33%) among patients treated emergently. After a mean follow-up of 49 ± 38 months, there were 12 aortic-related deaths (7.6%), including nine early deaths (5.7%) from perioperative complications and three late deaths (1.9%) from rupture. At 5 years, patient survival was 41%. Patients treated for CAAAs had higher 5-year freedom from ARM (P = .016), TA instability (P = .05), TA endoleak (P = .01), and TA secondary interventions (P = .05) with a higher, but non-significant, freedom from sac enlargement ≥5 mm (P = .11). Primary and secondary TA patency was 91% ± 2% and 99% ± 1%, respectively. Sac regression ≥5 mm occurred in 67 patients (43%) and was associated with increased survival (hazard ratio, 0.54; 95% confidence interval, 0.37-0.80) compared with those without sac regression.ConclusionsFB-EVAR using PMEGs was performed with acceptable long-term outcomes. Overall patient survival was low due to significant underlying comorbidities. Patients treated for CAAAs had higher freedom from ARM, TA instability, TA endoleak, TA secondary interventions, and a trend towards higher freedom from sac enlargement compared with patients treated for TAAAs. Sac regression was associated with improved patient survival. 相似文献

ObjectiveThe aim of our study was to evaluate patients who underwent extensive endovascular aortic stent graft coverage (from the aortic arch to abdominal aorta) in terms of early and midterm clinical outcomes.MethodsA retrospective multicenter study was undertaken. All patients were treated with extensive endovascular aortic stent graft coverage with fenestrated and branched endografts at three experienced endovascular centers.ResultsBetween 2012 and 2017, there were 33 patients (22 male [67%]) treated with a combination of fenestrated-branched stent grafts in the aortic arch and the thoracoabdominal aorta. Most of the patients (20/33 [61%]) had fenestrated-branched endovascular aneurysm repair (fb-EVAR) of the thoracoabdominal aorta as a second-stage procedure after thoracic arch (fb-Arch) repair, 10 had fb-Arch repair as the first procedure, and three patients had a single-stage procedure. The mean age was 67 ± 13 years, and the mean interval between procedures was 13 ± 12 months. For fb-Arch repair, 20 fenestrated and 13 branched devices were used; for fb-EVAR, 23 fenestrated, 5 branched, and 5 composite devices were used. The use of spinal drainage was more common in fb-EVAR (20/33 [61%]). Technical success was 100%. Mean hospital stay was 15 ± 13 days for fb-Arch repair and 12 ± 9 days for fb-EVAR. Two patients died in the hospital after fb-EVAR, resulting in a 30-day mortality of 6% (2/33). No deaths occurred during the fb-Arch repair component or in the single-stage cases. Four patients developed spinal cord injury (12%), 1 had permanent paraplegia (3%), and 2 patients had a neurologic event (1 stroke [3%] and 1 transient ischemic attack [3%]). Six patients (18%) died during a mean follow-up of 23 ± 17 months. The survival at 12 months after the second procedure was 72%, and the freedom from any reintervention was 82%. The 12-month freedom from reintervention was 87% for fb-Arch repair and 81% for fb-EVAR.ConclusionsExtensive endovascular coverage of the aorta for aortic disease seems to be a feasible procedure in experienced centers, with acceptable perioperative morbidity and mortality. Spinal cord ischemia appears acceptable despite extensive aortic coverage. 相似文献

BackgroundCure of aneurysms which involve the aorta at the level of the visceral arteries and the thoracoabdominal segment remains a considerable surgical enterprise with a relatively high mortality and morbidity despite improvements of the surgical procedure and anesthetic technique. Fenestrated and branched endovascular stent grafts are currently available offering an attractive less invasive option especially for most frail patients. These grafts are relatively recent, technically more demanding to insert than the current stent graft for infrarenal aneurysm and besides, given the relative low frequency of the disease, they are much less used by practitioners. Thus, unconditional widespread of this sophisticated technique may not necessarily benefit patients.MethodsWe reviewed our experiences and articles regarding this concern, 1) who should perform this new technique and 2) in what kind of setting.ConclusionBased on the combined complexities of 1) patients selection, 2) proper planning and manufacturing of the graft, 3) the need for outstanding imaging and operating facilities, 4) and the required endovascular skill of physicians involved in the procedure, we feel that only highly specialized centers should be allowed to perform this complex procedure. 相似文献

Objective
The aim of our study was to analyze the incidence of spinal cord ischemia (SCI) in patients presenting with complex aortic aneurysms treated with endovascular aneurysm repair (EVAR) and to identify risk factors associated with this complication.Methods
A retrospective study was undertaken of prospectively collected data including patients presenting with complex aortic aneurysm (pararenal abdominal aortic aneurysm and thoracoabdominal aortic aneurysm) treated with fenestrated EVAR (F-EVAR) or branched EVAR (B-EVAR). The primary end point was the incidence of SCI and the assessment of any associated factors.Results
Between January 2011 and August 2017, a total of 243 patients (mean aneurysm diameter, 65.2 ± 15.3 mm; mean age, 72.4 ± 7.5 years; 73% male) were treated with F-EVAR or B-EVAR. Asymptomatic patients were treated in 73% of the cases (177/243, in contrast to 27% urgent), and 52% (126/243) were treated for thoracoabdominal aortic aneurysm (in contrast to 48% for pararenal abdominal aortic aneurysm). F-EVAR (mean number of fenestrations, 3.3/case) and B-EVAR (mean number of branches, 3.7/case) were undertaken in 67% (164/243) and 33% (79/243), respectively. The total incidence of SCI was 17.7% [43/243; paraplegia in 4% (10/243) and paraparesis in 13.7% (33/243)]. Most of the patients with SCI presented with immediate postoperative symptoms (72% [31/43]). A spinal drain was preoperatively placed in 53% (130/243) and was associated with the prevention of SCI (SCI with spinal drainage, 12% [16/130]; SCI without spinal drainage, 24% [27/113]; P = .018). The 30-day mortality rate was 9% (21/243). After multiple logistic regression analysis, SCI was associated with preoperative renal function (SCI with preoperative glomerular filtration rate <60 mL/min/1.73 m2: odds ratio [OR], 2.43; 95% confidence interval [CI], 1.18-4.99; P = .016) and the number of vertebral segments covered (SCI with higher position of proximal stent in terms of vertebra: OR, 1.2; 95% CI, 1.1-1.3; P = .000). A similar outcome was derived when the height of the proximal end of the stent graft was replaced by the total length of aortic coverage (SCI with preoperative glomerular filtration rate <60 mL/min/1.73 m2: OR, 2.36 [95% CI, 1.11-5.00; P = .025]; SCI with longer length of aortic coverage: OR, 1.01 [95% CI, 1.003-1.009; P = .000]).Conclusions
The majority of SCI incidence after F-EVAR or B-EVAR of complex aortic aneurysms is manifested immediately postoperatively. The use of preoperative spinal drainage may prevent SCI. Patients with GRF <60 mL/min/1.73 m2 and with longer aortic stent graft coverage are at higher risk of SCI. 相似文献5.

ObjectiveTo determine the rates and risk factors of complications related to cerebrospinal fluid drainage (CSFD) during first stage and completion fenestrated-branched endovascular aortic repair (F-BEVAR) of pararenal and thoracoabdominal aortic aneurysms.MethodsWe reviewed the outcomes of 293 consecutive patients enrolled in a prospective, nonrandomized study to investigate outcomes of F-BEVAR between 2013 and 2018. Patients who received CSFD during first-stage thoracic endovascular aortic repair, index F-BEVAR, or completion of temporary aneurysm sac perfusion procedures were included in the analysis. CSFD complications were graded as severe or moderate if they were life threatening, escalated the level of care, or prolonged the hospital stay. Presence of substantial degenerative lumbar disease (DLD) was identified based on review of preoperative computed tomography. End points included technical difficulties during CSFD placement and CSFD-related complications.ResultsA total of 187 patients (mean age, 73 ± 8 years; 70% male) treated for 20 pararenal and 167 thoracoabdominal aortic aneurysms received CSFD in 240 procedures, including 51 first-stage thoracic endovascular aortic repairs, 184 index F-BEVARs, and 5 completion temporary aneurysm sac perfusion procedures. Nineteen patients (10%) had 22 CSFD-related complications after 21 aortic procedures (9%). Complications were graded as severe to moderate in 17 patients (9%). There were 12 patients (6%) with intracranial hypotension, including three (2%) who had intracranial hemorrhage and nine (5%) with post dural puncture headache requiring blood patches in six. Another six patients (3%) developed spinal hematomas resulting in paraplegia in two (1%) and transient paraparesis in two (1%). One patient had CSF leakage from the puncture site (no intervention required). Four patients had bleeding during attempted drain placement, which required postponement of F-BEVAR. Technical difficulties were experienced in 57 drain insertions (24%), more often in patients with DLD than in those without DLD (35/113 [31%] vs 22/121 [18%]; P = .03). Fluoroscopic guidance was used in 44 drain placements (18%) with a lower rate of technical difficulties compared with the blind approach (9% vs 28%; P = .01). There was a statistically nonsignificant trend toward more complications in patients with technical challenges (14% vs 7%; P = .10). Of 13 study patients who developed spinal cord injuries during aortic procedures, 4 (31%) were attributed to CSFD.ConclusionsAlthough CSFD is widely used to prevent ischemic spinal cord injury during complex aortic repair, the risk of major CSFD-related complications is not negligible and should be carefully weighed against its potential benefits. One-third of spinal cord injuries were caused by CSF drain placement. The use of fluoroscopic guidance may decrease the risk of CSFD-related complications. 相似文献

ObjectiveThe objective of this study was to investigate changes in health-related quality of life (QOL) in patients treated for pararenal aortic aneurysms (PAAs) and thoracoabdominal aortic aneurysms (TAAAs) with fenestrated-branched endovascular aneurysm repair (F-BEVAR).MethodsA total of 159 consecutive patients (70% male; mean age, 75 ± 7 years) were enrolled in a prospective, nonrandomized single-center study using manufactured F-BEVAR (2013-2016). All patients were observed for at least 12 months (mean follow-up time, 27 ± 12 months). Patients' health-related QOL was assessed using the 36-Item Short Form Health Survey questionnaire at baseline (N = 159), 6 to 8 weeks (n = 136), 6 months (n = 129), and 12 months (n = 123). Physical component scores (PCSs) and mental component scores (MCSs) were compared with historical results of patients enrolled in the endovascular aneurysm repair (EVAR) 1 trial who were treated by standard EVAR for simple infrarenal abdominal aortic aneurysms.ResultsThere were 57 patients with PAAs and 102 patients with TAAAs (50 extent IV and 52 extent I-III TAAAs). There were no 30-day deaths, in-hospital deaths, conversions to open surgery, or aorta-related deaths. Survival was 96% at 1 year and 87% at 2 years. Major adverse events occurred in 18% of patients, and 1-year reintervention rate was 14%. There were no statistically significant differences between the groups in 30-day outcomes. Patients treated for TAAAs had lower baseline scores compared with those treated for PAAs (P < .05). PCS declined significantly 6 to 8 weeks after F-BEVAR in both groups and returned to baseline values at 12 months in the PAA group but not in the TAAA group. Patients with TAAAs had significantly lower PCSs at 12 months compared with those with PAAs (P < .001). There was no decline in mean MCS. Major adverse events were associated with decline in PCS assessed at 6 to 8 weeks (P = .021) but not in the subsequent evaluations. Reinterventions had no effect on PCS or MCS. Overall, patients treated by F-BEVAR had similar changes in QOL measures as those who underwent standard EVAR in the EVAR 1 trial, except for lower PCS in TAAA patients at 12 months.ConclusionsPatients treated for TAAAs had lower scores at baseline in their physical aspect of health-related QOL. F-BEVAR was associated with significant decline in PCSs in both groups, which improved after 2 months and returned to baseline values at 12 months in patients with PAAs but not in those with TAAAs. Patients treated for PAAs had similar changes in QOL compared with those treated for infrarenal aortic aneurysms with standard EVAR. 相似文献

BackgroundComplex aortic pathology still represents an open issue in contemporary endovascular management, with continuous technological advancement being introduced in practice over time aiming to improve outcomes. Thus far, the dualism between the fenestrated and branched configuration for visceral artery revascularization is yet unsolved, with each approach having its own pros and cons. The inner branched technology for endovascular aneurysm repair (iBEVAR) aims to take the best out of both strategies, offering wide applicability and stable bridging stent sealing. The objective of this study was to evaluate the early outcomes obtained with a single manufacturer custom-made inner-branched endograft in a multicenter Italian experience.MethodsAll patients consecutively treated with E-xtra design devices in three Italian facilities were enrolled. Anatomic characteristics and perioperative data were analyzed. The main objective was to asses technical and clinical success after iBEVAR. Secondary end points were overall survival, aortic-related mortality, target visceral vessel (TVV) patency, and freedom from target vessel instability during follow-up.ResultsFrom 2016 to 2021, 45 patients were treated with an E-xtra design device revascularizing at least one visceral vessel through an inner branch. The mean age at the time of the procedure was 71.1 ± 9.3 years and 77.8% were males. The total number of target visceral arteries to be bridged with an inner branch was 159. The extent of aortic repair was thoracoabdominal in 91.1% of the cases. Technical success was achieved in 93.3% of the procedures (42/45) with all failures owing to a type I endoleak at final angiography. Each TVV was successfully connected to the graft’s main body as planned without complications. Following their intervention, five patients developed spinal cord ischemia and in three of these cases symptoms persisted after discharge (6.7%). At 30 days clinical success was 93.3% (42/45). No death as well as no TVV thrombosis occurred within 30 days from the primary procedures. The mean follow-up was 22.8 ± 14.2 months. The Kaplan-Meier estimate of overall survival and TVV patency at 36 months were 83.9% and 95.9%, respectively.ConclusionsInner branches seem to be a promising technology in the complex aortic repair landscape, with an applicability ranging from type II thoracoabdominal aneurysm to type I endoleak repair after infrarenal endografting. Whether iBEVAR could offer results comparable with those provided by fenestrated/branched endovascular aneurysm repair in terms of target vessel patency and stent stability is yet to be established and further studies are, therefore, needed. 相似文献

ObjectivePatients with postdissection thoracoabdominal aortic aneurysms (TAAAs) have been more likely to develop endoleaks than those with degenerative TAAAs after fenestrated or branched endovascular aortic repair (F/BEVAR). In the present study, we aimed to determine the risk factors for target vessel (TV)-related endoleaks after visceral segment F/BEVAR for postdissection TAAAs.MethodsWe performed a retrospective analysis of all patients with degenerative and postdissection TAAAs treated with F/BEVAR between 2017 and 2021. All the patients had undergone computed tomography angiography before and 3 months, 6 months, and annually after discharge. Two experienced vascular surgeons had used data from computed tomography angiography and vascular angiography to judge the presence of endoleaks. The study end points were mortality, aneurysm rupture, and the emergence of and reintervention for TV-related endoleaks.ResultsA total of 195 patients (mean age, 66 ± 10 years; 69% men) had undergone F/BEVAR for 99 postdissection TAAAs and 96 degenerative TAAAs. During a mean follow-up of 16 ± 12 months, we found that the patients with postdissection TAAAs were younger (age, 64 ± 10 years vs 69 ± 9 years; P = .001), had required more prior aortic repairs (58% vs 40%; P = .012), and had had a higher body mass index (26.1 ± 3.4 kg/m2 vs 24.8 ± 3 kg/m2; P = .008), a larger visceral segment aortic diameter (47.1 ± 7.5 mm vs 44.5 ± 7.5 mm; P = .016), and more TV-related endoleaks (18% vs 7%; P = .023) compared with those with degenerative TAAAs. Of the 99 patients with postdissection TAAAs, 327 renal–mesenteric arteries were revascularized using 12 scallops, 141 fenestrations, and 174 inner or outer branch stents. A total of 25 TV-related endoleaks were identified among 18 patients during follow-up, including 6 type Ic (retrograde from the distal end of the branch), 3 type IIIb (bridging stent fabric tear), and 16 type IIIc endoleaks (detachment or loose connection of the bridging stent). The patients with an endoleak had had a larger visceral aortic diameter (52.7 ± 6.4 mm vs 45.8 ± 7.2 mm; P < .001) and had undergone revascularization of more TVs (3.7 ± 0.7 vs 3.2 ± 0.9; P = .032). In contrast, true lumen compression did not seem to affect the occurrence of TV endoleaks (39% vs 27%; P = .323). The use of presewn branch stents in the fenestration position was associated with a lower risk of TV-related endoleaks (5% vs 11%; P = .025). In addition, TVs derived entirely or partially from the false lumen were more prone to the development of endoleaks after reconstruction (19% vs 4% [P < .001]; and 15% vs 4% [P = .047], respectively).ConclusionsWe found that patients with postdissection TAAAs were more likely to have TV-related endoleaks after F/BEVAR in the visceral region than those with degenerative TAAAs. Additionally, patients with a larger aortic diameter and a greater number of fenestrations in the visceral region were more likely to have experienced TV-related endoleaks. Branch vessels deriving from the false lumen were also more likely to develop endoleaks after reconstruction, and prefabricated branch stents were related to a lower possibility of TV-related endoleaks. 相似文献

Objective
Female sex has been associated with greater morbidity and mortality for a variety of major cardiovascular procedures. We sought to determine the influence of female sex on early and late outcomes after open descending thoracic aortic aneurysm (DTA) and thoracoabdominal aortic aneurysm (TAAA) repair.Methods
We searched our aortic surgery database to identify patients having open DTA or TAAA repair. Logistic regression and Cox regression analyses were used to assess the effect of sex on perioperative and long-term outcomes.Results
From 1997 until 2017, there were 783 patients who underwent DTA or TAAA repair. There were 462 male patients and 321 female patients. Female patients were significantly older (67.6 ± 13.9 years vs 62.6 ± 14.7 years; P < .001), had more chronic pulmonary disease (47.0% vs 35.7%; P = .001) and forced expiratory volume in 1 second <50% (28.3% vs 18.2%; P < .001), and were more likely to have degenerative aneurysms (61.7% vs 41.6%; P < .001). Operative mortality was not different between women and men (5.6% vs 6.2%; P = .536). However, women were more likely to require a tracheostomy after surgery (10.6% vs 5.0%; P = .003) despite a reduced incidence of left recurrent nerve palsy (3.4% vs 7.8%; P = .012). Logistic regression found female sex to be an independent risk factor for a composite of major adverse events (odds ratio, 2.68; confidence interval, 1.41-5.11) and need for tracheostomy (odds ratio, 3.73; confidence interval, 1.53-9.10). Women also had significantly lower 5-year survival.Conclusions
Women undergoing open DTA or TAAA repair are not at greater risk for operative mortality than their male counterparts are. Reduced preoperative pulmonary function may contribute to an increased risk for respiratory failure in the perioperative period. 相似文献10.

BackgroundAortic endovascular treatment with fenestrated or branched devices (f/bEVAR) requires a connection between the aortic graft and the visceral vessel (VV). However, data on the perioperative and long-term fate of the VVs remain scarce. The aim of our study was to evaluate the VV loss (VVL) according to the type of revascularization performed (fenestrations vs branched) and the necessity for adjunctive visceral procedures (AVPs).MethodsFrom 2012 to 2017, all f/bEVAR procedures for juxtarenal abdominal aortic aneurysms (JAAAs), pararenal abdominal aortic aneurysms (PAAAs), and thoracoabdominal aortic aneurysms (TAAAs) were considered. The perioperative VVL, AVPs, and graft configuration were considered and evaluated during the follow-up period.ResultsIn 158 patients, 523 VVs were considered, 140 (26%) in JAAAs, 165 (32%) in PAAAs, and 218 (42%) in TAAAs. Branches were used for 114 vessels (52%) in TAAAs, 8 (5%) in PAAAs, and 0 (0%) in JAAAs. The overall perioperative VVL was 20 (3.8%) and was significantly greater in TAAAs than in PAAAs or JAAAs (6.4% vs 2.4% vs 1.4%; P = .03). The branches resulted in greater perioperative VVL compared with fenestration (9% [11 of 122] vs 2% [9 of 401]; P = .0001). A significant VVL difference between the branches and fenestrations was identified selectively only for the renal arteries: 11 of 52 (21%) vs 6 of 224 (2.5%; P = .001). The results of the multivariate analysis confirmed the independent greater risk of VVL for branches and renal arteries (odds ratio, 4.7; 95% confidence interval, 12.5-1.7; P = .04; odds ratio, 7.1; 95% confidence interval, 52.6-1.05; P = .05, respectively). AVPs were performed in 43 VVs (8.2%) because of dissection (n = 2; 0.4%), stenosis (m = 3; 0.6%), bleeding (n = 3; 0.6%), or kinking between the bridging stent graft and the VV (n = 35; 7%). A significant difference between the branches and fenestrations was seen only for kinking between the bridging stent graft and VV (12% [15 of 112] vs 5% [20 of 401]; P = .005). At 5 years, the incidence of VVL was 2% ± 1%. The fenestrations had significantly greater freedom from VVL compared with the branches (100% vs 87% ± 6%; P = .04), which was confirmed selectively for TAAAs (100% vs 87% ± 6%; P = .04). The use of AVPs did not affect long-term visceral patency.ConclusionsEarly and late VVL was infrequent in complex aortic procedures but seemed to occur more frequently in branches than in fenestration, especially for renal arteries. AVPs were often required to correct artery kinking but this did not affect the long-term patency. 相似文献

ObjectiveOpen repair of extent II and III thoracoabdominal aortic aneurysms (TAAA) is associated with substantial morbidity. Alternative strategies, such as hybrid operations combining proximal thoracic endovascular aortic repair with either staged open distal TAAA repair or visceral debranching (hybrid), as well as fenestrated/branched endografts (FEVAR), have been increasingly reported; however, benefits of these approaches compared with direct open surgery remain unclear. The purpose of this study was to compare outcomes of these three different strategies in the management of extent II/III TAAA.MethodsAll extent II/III TAAA repairs (2002-2018) for nonmycotic, degenerative aneurysm or chronic dissection at a single institution were reviewed. The primary end point was 30-day mortality. Secondary end points included incidence of spinal cord ischemia (SCI), complications, unplanned re-operation, 90-day readmission, and out-of-hospital survival. To mitigate impact of covariate imbalance and selection bias, intergroup comparisons were made using inverse probability weighted-propensity analysis. Cox regression was used to estimate survival while cumulative incidence was used to determine reoperation risk.ResultsOne hundred ninety-eight patients (FEVAR, 92; hybrid, 40; open, 66) underwent repair. In unadjusted analysis, compared with hybrid/open patients, FEVAR patients were significantly older with more cardiovascular risk factors, but less likely to have a connective tissue disorder or dissection-related indication. Unadjusted 30-day mortality and complication rates were: 30-day mortality, FEVAR 4%, hybrid 13%, open 12% (P = .01); and complications, FEVAR 36%, hybrid 33%, open 50% (P = .11). Permanent SCI was not different among groups (FEVAR 3%, hybrid 3%, open 6%; P = .64). In adjusted analysis, 30-day mortality risk was greater for open vs FEVAR (hazard ratio, 3.6; 95% confidence interval, 1.4-9.2; P = .01) with no difference for hybrid vs open/FEVAR. There was significantly lower risk of any SCI for open vs FEVAR (hazard ratio, 0.3; 95% confidence interval, 0.09-0.96; P = .04); however, no difference in risk of permanent SCI was detected among the three groups. There was no difference in complications or unplanned reoperation, but open patients had the greatest risk of unplanned 90-day readmission. There was a time-varying effect on survival probability, with open repair having a significant survival disadvantage in the first 1 to 6 months after the procedure compared with hybrid/FEVAR patients (Cox model P = .03), but no difference in survival at 1 and 5 years (1- and 5-year survival: FEVAR, 86 ± 3%, 55 ± 8%; hybrid, 86 ± 5%, 60 ± 11%; open 69 ± 7%, 59 ± 8%; Cox-model P = .10).ConclusionsExtent II/III TAAA repair, regardless of operative strategy, is associated with significant morbidity risk. FEVAR is associated with the lowest 30-day mortality risk compared with hybrid and open repair when estimates are adjusted for preoperative risk factors. These data support greater adoption of FEVAR as first-line therapy to treat complex TAAA disease in anatomically suitable patients who present electively. 相似文献

ObjectiveA rational approach to the management of aortic aneurysm disease relies on weighing the risk of aneurysm rupture against the complications and durability of operative repair. In men, seminal studies of infrarenal aortic aneurysm disease and its endovascular management can provide a reasoned argument for the timing and modality of surgery, which is then extrapolated to the management of thoracoabdominal aortic aneurysms (TAAAs). In contrast, there is less appreciation for the natural history of TAAA disease in women and its response to therapy.MethodsWe used a retrospective cohort design of women, all men, and matched men, fit for complex endovascular thoracoabdominal aneurysm repair at two large aortic centers. We controlled for preoperative anatomic and comorbidity differences, and assessed technical success, postoperative renal dysfunction, spinal ischemia, and early mortality. Women and matched men were reassessed at follow-up for long-term durability and survival.ResultsAssessing women and all men undergoing complex endovascular aortic reconstruction, we demonstrate that these groups are dissimilar before the intervention with respect to comorbidities, aneurysm extent, and aneurysm size; women have a higher proportion of proximal Crawford extent 1, 2, and 3 aneurysms. Matching men and women for demographic and anatomic differences, we find persistent elevated perioperative mortality in women (16%) undergoing endovascular thoracoabdominal aneurysm repair compared with matched men (6%); however, at the 3-year follow-up, both groups have the same survival. Furthermore, women demonstrate more favorable anatomic responses to aneurysm exclusion, with good durability and greater aneurysm sac regression at follow-up, compared with matched men.ConclusionsWomen and unmatched men with TAAA disease differ preoperatively with respect to aneurysm extent and comorbidities. Controlling for these differences, after complex endovascular aneurysm repair, there is increased early mortality in women compared with matched men. These observations argue for a careful risk stratification of women undergoing endovascular thoracoabdominal aneurysm treatment, balanced with women's good long-term survival and durability of endovascular aneurysm repair. 相似文献

ObjectiveDespite numerous recent pivotal and small-scale trials, real-world endovascular management of juxtarenal aneurysms (JRA), suprarenal aneurysms (SRA), and thoracoabdominal aortic aneurysms (TAAA) remains challenging without consensus best practices. This study evaluated the mortality, graft patency, renal function, complication, and reintervention rates for fenestrated and parallel endografts in complex aortic aneurysms repairs.MethodsThis retrospective review of consecutive included patients with JRA, SRA, or TAAA who underwent complex endovascular repair from August 2014 to March 2017 at one high-volume institution. Treatment modality was a single surgeon decision based on patients anatomy and the urgency of the repair. Patient demographics, hospital course, and follow-up visits inclusive of imaging were analyzed. Ruptured aneurysms were excluded. Survival rates and outcomes were determined using the Kaplan-Meier method with log-rank tests.ResultsSeventy complex endovascular aortic repairs were performed; 38 patients with TAAA were treated with snorkel/sandwich parallel endografts (21 celiac, 28 superior mesenteric arteries, 58 renal arteries) and 32 patients with JRA/SRA were treated by fenestrated endovascular aneurysm repair (FEVAR) with 94 total fenestrations (2 celiac, 30 SMA, 62 renal). The mean patient age was 74.8 ± 10.0 years. Sixty percent were male, and the mean aortic aneurysm diameter was 6.0 ± 1.4 cm. Perioperative mortality was 3.1% (1/32) for FEVAR compared with 2.6% (1/38) for parallel endografts (P = .9). All-cause reintervention rates were 15.6% in FEVAR (5/32) vs 23.6% with parallel endografts (9/38; P = .4). Branch reintervention rates per each branch endograft were 4.3% for FEVAR (4/94; 2 renal stent occlusions, 1 colonic ischemia without technical issue found on reintervention, 1 perinephric hematoma) vs 3.7% for parallel endografts (4/107; 2 renal and 1 celiac stent thromboses, and 1 renal stent kink; P = .41). The endograft branch thrombosis rate was 2.1% in FEVAR (2/94) vs 2.7% in parallel endografts (3/109; P = .77). Reinterventions owing to endoleaks were performed in five patients (2 type I, 2 type III, and 1 gutter endoleak; 13.1%) with parallel grafts vs no endoleak reinterventions in FEVAR. The overall survival and freedom from aneurysm-related mortality at 24 months was 78% and 96.9% in FEVAR vs 73% and 93.4% for parallel endografts (P = .8 and P = .6). The median follow-up was 12 months (range, 1-32 months).ConclusionsParallel and fenestrated endografts have acceptable and comparable mortality and patency rates in endovascular treatment of JRA, SRA, and TAAA. This study reaffirms that parallel endografts are a safe and viable alternative to fenestrated devices for complex aortic aneurysmal disease despite often treating more urgent patients and more complicated anatomy unable to be treated with FEVAR. 相似文献

ObjectiveThe aim of this pilot study was to evaluate intraoperative contrast-enhanced ultrasound (iCEUS) examination for endoleak (EL) detection after complex endovascular aortic repairs (EVAR) in comparison with the standard angiographic completion control.MethodsTwenty-one patients (16 male; median age, 73 years [range, 54-81 years]) who underwent single-stage EVARs at our center between October 2016 and October 2018 were included prospectively. The procedures comprised fenestrated and/or branched EVAR (n = 14; 66%), infrarenal EVAR (n = 5; 24%), infrarenal EVAR with bilateral iliac side branch implantation (n = 1; 5%), and infrarenal EVAR with occluder implantation into the internal iliac artery (n = 1; 5%). The used endografts included 14 custom made devices (Cook, Australia Pty Ltd, Brisbane, Australia, n = 6; Vascutek Terumo, Glasgow, Scotland, n = 8) and seven standard infrarenal endografts (Medtronic Inc, Santa Rosa, Calif, n = 5; Vascutek Terumo, Glasgow, Scotland, n = 1; Cook, n = 1). All patients underwent an angiographic completion control for EL detection followed by iCEUS examination. The iCEUS examination was performed by the same examiner who was blinded to the angiography result. In addition to the comparison of the angiographic results to iCEUS examination, iCEUS examination was also compared with the computed tomography angiography (CTA) before discharge (median time to CTA, 5 days [range, 1-7 days]).ResultsAngiography detected eight type II EL, defining the EL origin in four cases. In addition to detecting all of those eight EL, iCEUS examination revealed eight more type II EL not seen on angiography (P = .002) and allowed a definition of the EL origin in all cases. CTA before discharge showed a persistence of only 5 of the 16 type II EL detected by iCEUS examination (31%, P = .002).ConclusionsAn iCEUS examination can be used as another adjunct to decrease exposure to contrast agent and radiation during EVAR, including complex procedures. A replacement of the completion angiography by iCEUS examination is conceivable for infrarenal EVAR, but also for endovascular type IV or type V repairs. Future studies with larger patient numbers will help to further validate iCEUS examination during complex EVAR. 相似文献

ObjectiveTo compare outcomes between octogenarians and nonoctogenarians undergoing thoracoabdominal aortic aneurysm repair and juxtarenal aortic aneurysm repair using branched and/or fenestrated endovascular devices (F/BEVAR) and compare octogenarian survival to population survival statistics from Ontario, Canada.MethodsPatients who underwent F/BEVAR at a single institution between 2007 and 2020 were retrospectively reviewed with a median follow-up of 3.3 years (interquartile range, 1.6-5.3). The median survival of an average 84-year-old Ontarian from Canada, adjusted for a male:female ratio of 4:1, was retrieved from publicly available Statistics Canada data.ResultsIn total, 68 octogenarians (25.8%) and 196 nonoctogenarians (74.2%) were included (mean age, 83.5 ± 3.0 vs 71.9 ± 5.8 years; P ≤ .001). The maximum aneurysm size was significantly larger in octogenarians (68.9 ± 11.4 mm vs 65.4 ± 10.0 mm; P = .017). No differences in the number of thoracoabdominal aortic aneurysm repairs (29.4% vs 38.3%; P = .19) or operative technical success (92.6% vs 85.7%; P = .136) were observed between the two cohorts. Postoperatively, no significant differences in overall in-hospital mortality (7.3% vs 5.1%; P = .49), elective in-hospital mortality (6.1% vs 4.4%; P = .49), stroke (1.5% vs 3.6%; P = .384), or spinal cord ischemia (2.9% vs 9.2%; P = .094) were seen between octogenarians and nonoctogenarians. There was no difference in survival at 4 years between the two cohorts (62.9% vs 71.1%; P = .22), however, survival at 6 years was significantly lower for octogenarians (44.5% vs 64.1%; hazard ratio, 1.96; P = .02). The cumulative rate of reintervention (44.1% vs 41.3%; P = .84) and freedom from branch instability (67.6% vs 73.5%; P = .33) at 6 years were not different between the two groups. When comparing octogenarians who survived to discharge from index hospitalization after F/BEVAR with 84-year-old Ontarians unmatched for comorbidities, a survival difference of 4.8% and 11.1% was noted at 4 and 6 years, respectively.ConclusionsF/BEVAR in octogenarians is associated with no differences in technical success or postoperative adverse outcomes when compared with their younger counterparts. Octogenarians had increased mortality after 4 years and their survival at 4 years was comparable with that of an 84-year-old Ontarian. F/BEVAR was safe and effective in octogenarians deemed fit for intervention. Further research into preoperative patient selection and improving perioperative outcomes is needed. 相似文献

Fenestrated-branched endovascular repair has been applied to treat chronic postdissection thoracoabdominal aortic aneurysms (TAAAs). We report a patient with diffuse postdissection aortic aneurysm involving the arch and thoracoabdominal aorta treated in a staged fashion with redo aortic arch repair using the frozen elephant trunk technique, followed by completion endovascular TAAA using preloaded guidewire system and a five-vessel fenestrated and branched stent graft. A technical video illustrates the use of onlay fusion and sequential catheterization with the preloaded guidewire system to facilitate TAAA repair. 相似文献

BackgroundEvidence to guide management of postdissection abdominal aortic aneurysms (PDAAA) is lacking. This study describes the outcomes of open repair of PDAAA.MethodsA retrospective cohort study was conducted of all consecutive patients treated with open repair for PDAAA after a Stanford type A or type B thoracic aortic dissection between January 2006 and December 2017 in two vascular referral centers. Preceding type B dissection treatment could include conservative or surgical management. Primary outcomes were 30-day mortality, complication rates, survival, and reintervention-free survival. Survival and reintervention-free survival were analyzed using the Kaplan-Meier method. Reintervention was defined as any endovascular or surgical intervention after the index procedure.ResultsIncluded were 36 patients (27 men [75%]) with a median age of 64 years (range, 35-81 years). The 30-day mortality was 2.7%. The median follow-up was 16 months (range, 0-88 months). The postoperative course was uneventful in 21 patients (58%). The most frequent complications were postoperative bleeding requiring repeat laparotomy (n = 4), pneumonia (n = 3), congestive heart failure (n = 2), new-onset atrial fibrillation (n = 2), mesenteric ischemia requiring left hemicolectomy (n=1), and ischemic cerebrovascular accident (n = 1). Renal failure requiring hemodialysis developed in one patient. The overall survival at 1 year was 88.8%. Reintervention-free survival was 95.5% after 1 year and 88.6% after 2 years.ConclusionsOpen repair of PDAAA can be performed with a low mortality rate and an acceptable complication rate, comparable with elective open repair of abdominal aortic aneurysms without dissection. 相似文献

Background
Patients with juxtarenal aortic aneurysms who are unfit for open repair may be considered for fenestrated endovascular repair (fenEVAR). We report our initial experience with fenEVAR.Methods
We reviewed the data on all our patients receiving fenEVAR for juxtarenal aortic aneurysms.Results
Eight patients, average age 75 years, underwent fenEVAR. Endografts were designed from details obtained from preoperative computed tomography angiography. There were 6 grafts with superior mesenteric scallops and bilateral renal fenestrations, 1 with bilateral renal scallops, and 1 with a single renal fenestration. All patients survived 30 days. There was no renal failure requiring dialysis. At 10 weeks, 1 patient died from acute intestinal ischemia and multisystem organ failure, and another died from respiratory failure.Conclusions
It is feasible to offer fenEVAR to patients who are poor candidates for open repair. However, these procedures are technically challenging. Early outcomes are less favorable than other aortic endovascular procedures. 相似文献20.
