Objective
Mesenteric angioplasty and stenting (MAS) has surpassed open revascularization as the treatment of choice for mesenteric ischemia. Despite the lower perioperative mortality associated with MAS, the need for reintervention is not infrequent. The purpose of this study was to review the outcomes of patients treated for mesenteric artery in-stent restenosis (MAISR).Methods
Clinical data from a single center between 2004 and 2017 were retrospectively analyzed. Standard statistical analysis including Kaplan-Meier estimate for time-dependent outcomes, χ2 test for categorical variables, and two-sample t-test for continuous variables was performed. Primary end points included stent patency and reintervention rate. Secondary end points included mortality and morbidity.Results
During the study period, 91 patients underwent primary MAS. In total, 113 mesenteric vessels were treated with 20 covered stents and 93 bare-metal stents. Overall primary patency was 69% at 2 years. At 2 years, primary patency was 83% for covered stents compared with 65% for bare-metal stents (P = .17). Of these 91 primary MAS patients, 27 (30%) were treated for MAISR (32 vessels). Two covered stent patients developed significant restenosis (11%) compared with 25 (34%) bare-metal stent patients (P = .02). The mean age of patients requiring reintervention was 69 years (36% male), with the majority having a history of tobacco use (85%), hypertension (75%), and hyperlipidemia (78%). Fourteen reintervention patients (52%) presented with recurrent symptoms, 10 (37%) had asymptomatic restenosis, and 3 (11%) developed intestinal ischemia. Twelve patients (44%) underwent reintervention with balloon angioplasty alone and 15 (56%) underwent repeated stent placement. Of the 15 patients who had repeated stent placement, 7 patients had covered stents placed. The 30-day mortality rate after reintervention for mesenteric stent restenosis was 0%. Postoperative complications occurred in 15% of patients (myocardial infarction, 4%; reversible kidney injury, 4%; and bowel ischemia requiring surgical exploration, 7%). There was no difference in the perioperative morbidity in comparing symptomatic and asymptomatic patients undergoing reintervention. Mean follow-up after mesenteric reintervention was 31 months, with one-third of patients (n = 9) requiring another reintervention because of either recurrence of symptoms or asymptomatic high-grade restenosis. Assisted primary patency at 2 years was 92% after reintervention with balloon angioplasty and 87% for repeated stent placement, with no statistically significant difference between the groups (P = .66).Conclusions
Treatment of MAISR is associated with low mortality and acceptable morbidity. The initial use of covered stents may reduce the need for reintervention. 相似文献2.

Objective
The purpose of this study was to investigate the outcomes of patients undergoing advanced hybrid coronary revascularization, defined as robotic beating-heart multivessel totally endoscopic coronary artery bypass combined with percutaneous coronary intervention.Methods
This is a retrospective study. Among 308 consecutive patients who underwent totally endoscopic coronary artery bypass, 57 who underwent advanced hybrid coronary revascularization (mean age, 65.6 years) from July 2013 to September 2017 were included. Midterm survival and freedom from major adverse cardiac events, including death, myocardial infarction, and repeat revascularization, were analyzed.Results
Multivessel totally endoscopic coronary artery bypass was successfully performed without conversion to thoracotomy. Bilateral internal thoracic artery grafting was used in 50 patients (87.7%). The mean operative time was 318.4 ± 51.0 minutes. The mean length of hospital stay was 3.0 ± 1.3 days. There was no 30-day mortality. Percutaneous coronary intervention was planned after totally endoscopic coronary artery bypass in 51 patients (89.4%). The target lesions were the right coronary artery only in 38 patients, the left circumflex artery only in 4 patients, and multiple lesions in 13 patients. Eventually, 2 patients did not receive percutaneous coronary intervention. Percutaneous coronary intervention attempt was unsuccessful in 8 lesions. Patency of the left/right internal thoracic artery was 95.2% (60/63) and 95.7% (45/47), respectively. Graft patency was 95.2% (40/42) in the left circumflex artery and 93.3% (14/15) in the diagonal branch. Three-year survival was 92.8%, and 3-year freedom from major adverse cardiac events was 80.2%.Conclusions
Advanced hybrid coronary revascularization is a safe and less-invasive approach with short hospital stay and good midterm outcomes. 相似文献3.

Objective
The association between beta blockers and cardiovascular or limb-related outcomes after revascularization for critical limb ischemia (CLI) remains unclear. The objective of this study was to assess the impact of preoperative beta blockade on 30-day major adverse cardiac events (MACEs) and major adverse limb events (MALEs) in patients undergoing infrainguinal revascularization for CLI. We hypothesized that rates of MALEs and MACEs will be higher in patients not receiving preoperative beta blockade.Methods
The National Surgical Quality Improvement Program vascular targeted file for 2011 to 2014 identified patients receiving beta blockade and undergoing infrainguinal endovascular intervention and open bypass for CLI. Primary outcomes including 30-day MACE (stroke, myocardial infarction [MI], or death) and MALE (untreated loss of patency, reintervention, or amputation) were compared between patients taking and not taking preoperative beta blockers. Multivariate logistic regression identified independent predictors of MACEs and MALEs.Results
A total of 11,785 revascularizations were performed for CLI during the study period (7408 bypasses vs 4377 endovascular interventions). Preoperative beta blockers were used by 7365 patients, including 4541 (61.7%) in the open bypass cohort and 2824 (64.5%) in the endovascular group (P < .01). MACEs and MI were significantly higher in patients with preoperative beta blockers (MACEs, 5.8% vs 3.4% [P < .0001]; MI, 3.1% vs 1.8% [P < .0001]). After controlling for cardiac risk factors, beta blockers independently predicted MACEs (odds ratio [OR], 1.27; P = .03) and MI (OR, 1.36; P = .03) but not stroke (OR, 1.17; P = .58) or 30-day mortality (OR, 1.22; P = .19). Beta-blocker use did not have an effect on MALEs (OR, 0.99; P = .88).Conclusions
In patients with CLI, preoperative beta blockade was an independent predictor of 30-day MI and MACEs after controlling for other cardiovascular risk factors. Beta blockers did not have an impact on short-term limb-related outcomes. The association between beta blockade and revascularization for CLI deserves further investigation. 相似文献4.

Objective
Cardiac paragangliomas are rare neuroendocrine tumors. Early surgical treatment improves clinical symptoms and prolongs survival. We review our experience in 17 patients who underwent surgical resection for functional cardiac paraganglioma.Methods
Seventeen patients underwent surgery for functional cardiac paraganglioma from 2004 to 2017 were identified. Clinical data and long-term outcomes were extracted and analyzed.Results
All 17 patients with cardiac paraganglioma (11 males) with a median age of 35 years (range, 11 to 51 years) were hormonally functional and underwent operations. A 24-hour urine catecholamine assay documented elevation of norepinephrine, epinephrine, and dopamine. Tumors were determined with octreotide scintiscan in all 17 patients and metaiodoben-zylguanidine scintigraphy in 10 of 15 patients. Tumor sites were right atrioventricular groove in 4 patients, between the main arteries in 10 patients, and interatrial groove in 4 patients. All patients underwent complete resection. Concomitant surgeries were: structural reconstruction in 16 patients (94%) and coronary artery bypass graft in 8 patients (47%). One patient had a history of incomplete resection of an intra-atrial tumor. One patient died postoperatively. Operative mortality is 5.8%. During follow-up (mean, 6.5 years; range, 1.5 to 14.2 years), 16 patients are alive in functional class I or II. Two patients developed tumor recurrence and 14 remained symptom-free with normal urinary catecholamines.Conclusions
With a multidisciplinary treatment, early diagnosis, complete resection for the tumor along with complex reconstruction is achievable for most patients, and it offers promising long-term survival. 相似文献5.

Background
Acute mesenteric ischemia (AMI) is a challenging clinical problem associated with significant morbidity and mortality. Few contemporary reports focus specifically on patients undergoing open mesenteric bypass (OMB) or delineate outcome differences based on bypass configuration. This is notable, because there is a subset of patients who are poor candidates for endovascular intervention including those with flush mesenteric vessel occlusion, long segment occlusive disease, and a thrombosed mesenteric stent and/or bypass. This analysis reviewed our experience with OMB in the treatment of AMI and compared outcomes between patients undergoing either antegrade or retrograde bypass.Methods
A single-center, retrospective review was performed to identify all patients who underwent OMB for AMI from 2002 to 2016. A preoperative history of mesenteric revascularization, demographics, comorbidities, operative details, and outcomes were abstracted. The primary end point was in-hospital mortality. Secondary end points included complications, reintervention, and overall survival. Kaplan-Meier estimation and Cox proportional hazards regression were used to analyze all end points.Results
Eighty-two patients (female 54%; age 63 ± 12 years) underwent aortomesenteric bypass (aortoceliac/superior mesenteric, n = 44; aortomesenteric, n = 38) for AMI. A history of prior stent/bypass was present in 20% (n = 16). A majority (76%; n = 62) underwent antegrade bypass and the remainder received retrograde infrarenal aortoiliac inflow. Patients receiving antegrade OMB were more likely to be male (53% vs 25%; P = .02), have coronary artery disease (48% vs 25%; P = .06), chronic obstructive pulmonary disease (52% vs 25%; P = .03), and peripheral arterial disease (60% vs 35%; P = .05). Concurrent bowel resection was evenly distributed (antegrade, 45%; retrograde, 45%; P = .9) and 37% (n = 30) underwent subsequent resection during second look operations. The median duration of stay was 16 days (interquartile range, 9-35 days) and 78% (n = 64) experienced at least one major complication with no difference in rates between antegrade/retrograde configurations. In-hospital mortality was 37% (n = 30; multiple organ dysfunction, 22; bowel infarction, 4; hemorrhage/anemia, 2; arrhythmia, 1; stroke, 1; 30-day mortality, 26%). The median follow-up was 8 months (interquartile range, 1-26 months). The 1- and 3-year primary patency rates were both 82% ± 6% (95% confidence interval, 71%-95%), with 10 patients requiring reintervention. Estimated survival at 1 and 5 years was 57% ± 6% and 50% ± 6%, respectively. Bypass configuration was not associated with complication rates (P > .10), in-hospital mortality (log-rank, P = .3), or overall survival (log-rank, P = .9). However, a higher risk of reintervention was observed in patients undergoing retrograde bypass (hazard ratio, 3.0; 95% confidence interval, 0.9-11.0; P = .08).Conclusions
OMB for AMI results in significant morbidity and mortality, irrespective of bypass configuration. Antegrade OMB is associated with comparable outcomes as retrograde OMB. The bypass configuration choice should be predicated on patient presentation, anatomy, physiology, and surgeon preference; however, an antegrade configuration may provide a lower risk of reintervention. 相似文献6.

Background
Subclavian artery revascularization is frequently performed in the setting of thoracic endovascular aortic repair (TEVAR). However, there is little information on the short- and long-term outcomes of patients undergoing carotid to subclavian artery bypass in this clinical setting. As such, this study sought to define the early and late outcomes associated with this procedure.Methods
Patients undergoing carotid-subclavian bypass in conjunction with TEVAR between June 2005 and September 2016 were retrospectively identified from a prospectively maintained, single-center aortic surgery database. The 30-day outcomes specific to the carotid-subclavian bypass procedure were analyzed, including cervical plexus nerve injury, bleeding complications, and local vascular complications. All preoperative and postoperative chest radiographs were carefully analyzed to assess for hemidiaphragm elevation indicative of phrenic nerve palsy. Long-term outcomes included primary graft patency and anastomotic complications.Results
Of 579 consecutive patients undergoing TEVAR during this time interval, 112 patients (19%) underwent concomitant carotid-subclavian bypass. The cohort was 38% female (n = 43), with a mean age of 65 ± 14 years. The majority of conduits were 8-mm polytetrafluoroethylene grafts (n = 107 [95.5%]), with a minority being reversed saphenous vein (n = 4 [3.6%]) or Dacron (n = 1 [0.9%]) grafts. The bypass procedure was done concurrently at the time of TEVAR in 91% (n = 102) of cases. The short-term complication rate attributed specifically to the carotid-subclavian bypass was 29% (n = 33). These complications included phrenic nerve palsy in 25% (n = 27), recurrent laryngeal nerve palsy in 5% (n = 6), axillary nerve palsy in 2% (n = 2), and neck hematoma requiring re-exploration in 1% (n = 1) of patients. The 30-day in-hospital all-cause mortality rate was 5% (n = 6), and the rate of permanent paraparesis or paraplegia was 0.9% (n = 1). Of the operative survivors (n = 106), follow-up imaging of the bypass graft was available in 87% (n = 92) of patients. Actuarial primary graft patency was 97% at 5 years. There were three patients (3%) with bypass graft occlusions, two of which were clinically silent and detected on follow-up imaging. The third was detected because of symptoms of subclavian steal and required repeated revascularization. Two patients (2%) developed a late anastomotic pseudoaneurysm requiring either endovascular (n = 1) or surgical (n = 1) intervention.Conclusions
Carotid-subclavian bypass for revascularization of the subclavian artery performed in the setting of TEVAR is durable, although the true complication rate is likely higher than is generally reported in the literature because of a not insignificant rate of phrenic nerve palsy. These data should serve well as “gold standard” comparison data for emerging branch graft devices. 相似文献7.

Objective
Long-term outcomes after endovascular aneurysm repair (EVAR) are threatened by aortic neck dilation (AND), graft migration, and subsequent endoleak development. The aim of this study was to determine the rate of AND and the occurrence of endoleaks after fenestrated EVAR of juxtarenal aneurysms with physician-modified endovascular grafts (PMEGs).Methods
The study included 77 patients presenting with asymptomatic and ruptured juxtarenal abdominal aortic aneurysms treated with PMEGs who received radiologic follow-up. Analysis of computed tomography images took place on a three-dimensional workstation (TeraRecon, San Mateo, Calif). Aortic neck diameter was measured before and after EVAR at the lowest patent renal artery outer wall to outer wall. Significant AND was defined as >3-mm increase between baseline and follow-up, and sac regression >5 mm was considered significant. The patient's 1-month initial postoperative computed tomography measurement was considered baseline. The rate of AND was measured by comparing the baseline measurement with measurements at 6 months, 12 months, and annually thereafter up to 4 years.Results
In this cohort of patients, 75% were men with a mean age of 74 ± 7.9 years. Median preoperative aneurysm size was 62 (57-73) mm, and median follow-up was 12 (3.5-30) months. Mean endograft oversizing was 17% ± 12.5%, and mean seal zone length was 41 ± 11 mm. At 1-year follow-up, the median aortic neck increase was 1.7 (0-3) mm. Maximum aneurysm size decreased dramatically during the first postoperative year, with significant sac regression in 65% of the patients. Aortic neck diameter at 1 year did correlate positively with the percentage of device oversizing. No other correlations were found. During the 4-year follow-up, there were no cases of type IA endoleaks.Conclusions
AND does not influence outcome after endovascular repair of juxtarenal aneurysms using PMEGs. These midterm results support the applicability of PMEGs in juxtarenal aneurysm repair. 相似文献8.

Objective
The objective of this study was to investigate the factors associated with the complication rate and treatment outcomes of arteriovenous malformations (AVMs) during a 20-year period.Methods
This was a retrospective study of 306 patients (135 men, 171 women; mean age, 30.8 years) with body and extremity AVMs who were treated between 1996 and 2017. A total of 913 sessions of endovascular treatment were performed. Patients were divided into two decades of the study period to compare complications and clinical results. Group 1 comprised 107 patients treated in the first decade of the study period, and group 2 comprised 199 patients treated in the last decade. AVMs were classified according to the angiographic findings. Complication rates, number of treatment sessions, and treatment results were compared between the two groups.Results
Minor complication (group 1, 20.1%; group 2, 18.5%) and major complication (group 1, 3.1%; group 2, 4.1%) rates were similar between groups (P = .79). The mean number of treatment sessions in group 1 and group 2 was 4.2 and 2.3, respectively, indicating a 45% reduction in treatment sessions (P < .0001). The treatment failure rate decreased from 9.3% in group 1 to 1.5% in group 2 (P = .04). The clinical success rate was 54.2% in group 1 and 64.3% in group 2 (P = .10).Conclusions
With an accumulation of AVM treatment experience, the number of treatment sessions and the rate of treatment failures were significantly reduced. 相似文献9.

Objective
The primary objective was to evaluate the safety of transfer, type of procedure, and factors associated with limb salvage in patients with acute limb ischemia (ALI) treated at a quaternary referral center.Methods
A retrospective review of all patients with ALI secondary to thrombotic or embolic occlusion at a quaternary referral hospital from 2013 to 2016 was conducted. Patients were transferred from throughout Washington and Alaska by ambulance, helicopter, or fixed-wing modes of transportation. Demographics, transport and operative timing, Rutherford classification, level of occlusion, procedural information, and fasciotomy characteristics were reviewed. Outcomes measured included limb salvage rates, discharge disposition, and mortality.Results
One hundred twelve patients with ALI were identified, with 82% due to thrombosis and 18% due to arterial embolization. Fifty-seven percent of patients were transferred from a referring hospital with low mean transfer times (1.9 hours for embolic, 2.7 hours for thrombotic). Although the initial operative strategy varied according to the etiology, with 50% of thrombotic occlusions treated with endovascular therapies and 80% of embolic occlusions treated with open thrombectomy, the rates of limb salvage did not vary based on operative approach (92% endovascular first, 90% open first). Further, limb salvage rates were identical between transferred and nontransferred patients (77%). Limb salvage was successful in 91% of patients with Rutherford class 1 and 2 disease, but only 8% in patients with Rutherford class 3 disease. In-hospital and 30-day mortality rates were not different based on ischemic etiology (5%), although patients with Rutherford class 3 disease had significantly higher mortality rates (15%) compared with patients with class 1 (6%), class 2a (6%), and class 2b (2%) disease. Fasciotomy was performed in 29% of patients, with 59% of fasciotomy wounds closed primarily. Predictors of amputation include multiple attempts at limb salvage, higher Rutherford class, multilevel occlusion, more proximal levels of occlusion, and nonviable muscle seen after fasciotomy, with ischemic times trending toward higher amputation rates without statistical significance. There was no difference in discharge disposition based on ischemic etiology.Conclusions
The modern treatment of patients with ALI is effective, with high rates of limb salvage and low mortality regardless of transfer status, etiology, or initial operation performed. In situations where compartment syndrome is unclear, fasciotomy should not be withheld because it provides valuable predictive information regarding limb salvage. 相似文献10.
Study Design
Two-group randomized controlled trial.Introduction
Upper limb orthoses worn during functional tasks are commonly used in pediatric neurologic rehabilitation, despite a paucity of high-level evidence.Purpose of the Study
The purpose of this study was to investigate if a customized functional wrist orthosis, when placed on the limb, leads to an immediate improvement in hand function for children with cerebral palsy or brain injury.Methods
A 2-group randomized controlled trial involving 30 children was conducted. Participants were randomized to either receive a customized functional wrist orthosis (experimental, n = 15) or not receive an orthosis (control, n = 15). The box and blocks test was administered at baseline and repeated 1 hour after experimental intervention, with the orthosis on if randomized to the orthotic group.Results
After intervention, there were no significant differences on the box and blocks test between the orthotic group (mean, 10.13; standard deviation, 11.476) and the no orthotic group (mean, 14.07; standard deviation, 11.106; t[28], ?0.954; P = .348; and 95% confidence interval, ?12.380 to 4.513).Discussion
In contrast to the findings of previous studies, our results suggest that a functional wrist orthosis, when supporting the joint in a ‘typical’ position, may not lead to an immediate improvement in hand function.Conclusions
Wearing a functional wrist orthosis did not lead to an immediate improvement in the ability of children with cerebral palsy or brain injury to grasp and release. Further research is needed combining upper limb orthoses with task-specific training and measuring outcomes over the medium to long term. 相似文献11.

Objective
The objective of this study was to evaluate the long-term estimates of limb salvage and survival in patients with acute limb ischemia (ALI) receiving open surgery or endovascular revascularization.Methods
This was a retrospective consecutive cohort study of patients with ALI who underwent open surgery or endovascular treatment at the Vascular and Endovascular Surgery Unit, Hospital do Servidor Público Estadual (São Paulo, Brazil), between July 2010 and July 2016. The overall mortality, limb salvage, and survival rates at 720 days were analyzed in both the open surgery (group 1) and endovascular treatment (group 2) groups.Results
A total of 69 patients were admitted for a limb salvage procedure. The mean follow-up period was 822 ± 480.5 days. All of the analyses were performed at 720 days. Of the 69 patients, 46 (66.6%) were in group 1 and 23 (33.4%) in group 2. The clinical characteristics were similar between the groups, except for higher rates of chronic kidney disease (P = .04) and arrhythmia (P = .01) in group 1. Group 1 had a higher postoperative ankle-brachial index (P = .03). Concerning the Rutherford classification, group 1 had a higher prevalence of Rutherford IIB ALI (P = .003). The preoperative creatine kinase level was higher in group 1 than in group 2 (780 [range, 198-6546] mg/dL and 245 [65-78] mg/dL, respectively). A creatine kinase level >200 mg/dL was seen in 65.2% and 47.8% of patients in group 1 and group 2, respectively (P = .028). The limb salvage and overall survival estimates at 720 days were similar between group 1 and group 2 (79.2% vs 90.6% [P = .27] and 53% vs 60.8% [P = .45], respectively). The overall mortality rate was 10.1% (seven patients) within the first 30 days, and it was higher in group 1 (six patients [13.0%]; P = .03).Conclusions
Both open surgery and endovascular procedures are safe treatments of patients with ALI, with acceptable limb salvage and survival rates. No previous study has suggested the preferred treatment of ALI. However, based on this study and the overall literature, endovascular treatment may be the preferred treatment of patients with Rutherford I and IIA ALI; open surgery may be the best option for ALI due to arterial embolism and for Rutherford IIB acute arterial thrombosis because of a greater urgency to restore blood flow. 相似文献12.

Objective
Total arch replacement (TAR) is an established standard surgical procedure. We report >1000 cases of TAR using a 4-branched graft with antegrade cerebral perfusion (ACP) during a 15-year period.Methods
Since May 2001, 1005 patients who underwent total aortic replacement (mean age 69.8 ± 11.2 years; range, 9-92 years; 744 male) underwent TAR with a 4-branched graft. All surgeries were performed under hypothermia with ACP. There were 252 emergent operations for acute aortic dissection or aneurysm rupture. Concomitant operations included coronary arterial bypass grafting in 196 patients, aortic valve repair or replacement in 64, and aortic root replacements in 38.Results
The operation time was 482 ± 171 minutes, cardiopulmonary time was 254 ± 94 minutes, cardiac ischemia time was 145 ± 51 minutes, ACP time was 160 ± 47 minutes, and lower body circulatory arrest time was 62 ± 16 minutes. The hospital mortality rate was 5.2%. The permanent neurological dysfunction rate was 3.6% and temporary neurological dysfunction rate was 6.4%. There were no spinal cord complications. The 5-year survival rate was 80.7% and 10-year survival rate was 63.1%. Fifteen patients (1.5%) underwent reoperation for the arch grafts because of a pseudoaneurysm (11 patients), hemolysis (3 patients), and infection (1 patient).Conclusions
TAR using a 4-branched graft with ACP could be accomplished with acceptable short- and long-term results. 相似文献13.

Background
Existing endovascular therapies for failing infrainguinal bypass grafts are associated with modest patency rates. The use of everolimus drug-eluting stents (eDESs) for endovascular bypass graft revision has not yet been reported. The objective of this study was to describe and to compare clinical outcomes of eDESs vs percutaneous cutting balloons (PCBs) vs percutaneous transluminal angioplasty (PTA) for the treatment of infrainguinal bypass graft stenoses.Methods
A multicenter, single-institution retrospective analysis of patients with infrainguinal bypass graft stenoses treated by endovascular intervention (August 2010-December 2017) was conducted. The primary study outcome was primary patency of the treated lesion. The secondary outcome was limb salvage. Outcomes are described overall and stratified by endovascular treatment modality using Kaplan-Meier curves and log-rank tests.Results
During the 7-year study period, 43 patients with 78 infrainguinal bypass stenoses were treated by endovascular intervention (eDES, 15; PCB, 23; PTA, 40). Mean age was 63.3 ± 1.7 years, 53.5% were male, and 55.8% were black. The majority of patients were diabetic (60.5%) with a history of smoking (74.4%), and nearly all (83.7%) had two or more comorbidities. Half (48.7%) of bypasses treated were femoral-popliteal bypasses, followed by popliteal-distal (25.6%) and femoral-tibial (25.6%) configurations. The location of revision was the proximal anastomosis in 37.2%, midbypass in 25.6%, and distal anastomosis in 37.2%. There were no significant differences in baseline characteristics, bypass configuration, or revision location between treatment groups (P ≥ .19). Technical success for endovascular bypass intervention was 100%. At 2 years after intervention, primary patency was significantly better for patients treated with eDES (81.8%) compared with PCB (54.7%) or PTA (33.2%; log-rank, P = .03). Limb salvage was achieved in 93.6% of patients, including 86.7%, 91.3%, and 97.5% for eDES, PCB, and PTA, respectively (P = .30).Conclusions
This is the first study reporting the results of eDESs for the treatment of infrainguinal bypass graft stenoses. Use of eDESs for endovascular bypass graft revision not only is feasible but may have better primary patency than other endovascular therapies. These data suggest that eDESs may be considered a safe and efficacious endovascular technique in the armamentarium for treatment of infrainguinal bypass graft stenoses. 相似文献14.

Objective
The aim of this study was to evaluate the radiologic outcomes of open reduction and lateral plating with wiring in the treatment of Vancouver B2 periprosthetic femoral fractures.Methods
We retrospectively recruited 37 patients treated with ORIF with lateral plating and wiring for Vancouver B2 fractures. The 27 patients (15 men and 12 women; mean age: 70.8 ± 8.3 years) without follow-up loss had achieved complete bony union without notable complications. The average union period was checked after operation with radiologic findings. Radiologic outcomes were evaluated by ipsilateral limb length discrepancy (LLD) and subsidence between immediate postoperative length and length at postoperative 1 year after adjusting for magnification differences. The average distance to which the retained stem sunk down was investigated between immediate postoperative radiographs and final radiographs showing union.Results
Ten patients could not be evaluated, because of mortality or failure to follow up. The average time to union was 18.3 weeks, and the average distance of stem sinking was 2.5 ± 1.7 mm (range: 0–7.2 mm), which was significantly different between immediate postoperative radiographs and final radiographs. There was no case with loss of reduction or loss of fixation, requiring revision surgery.Conclusion
Open reduction and lateral plating with wiring as a treatment for Vancouver B2 periprosthetic femoral fractures produced good radiologic outcomes with successful bony union. ORIF can be considered the alternative option for treating patients with Vancouver B2 PPF, instead of stem revision surgery.Level of evidence

Purpose
Creating a trough on the anterior glenoid rim is one of the methods used for arthroscopic Bankart repair with suture anchors. The purpose of this study was to analyze clinical and radiological outcomes of arthroscopic Bankart repair with suture anchors; to compare between the outcomes of surgical procedures with and without trough.Methods
Clinical and radiological outcomes were evaluated for 116 patients who underwent arthroscopic Bankart repair at our institute from 2005 to 2011. The mean follow-up was 5.2 years (range, 2–8.8 years). All data were divided into trough group (n = 62) and non-trough group (n = 71). Clinical and functional outcomes were assessed pre- and postoperatively as range of motion (ROM), pain on the visual analog scale (p-VAS), function on the visual analog scale (f-VAS), and Rowe score. Radiological outcomes were also evaluated.Results
The overall postoperative clinical and functional outcomes improved significantly (P < .001). A total of 8 patients (6.8%) showed recurrent instability. Radiologic findings showed mild arthritis in 27 cases (23.1%), moderate arthritis in 6 cases (5.1%), and no severe arthritis. 32 patients showed anterior apprehension after surgery, and 22 out of those 32 patients were from non-trough group. However, no significant difference between the trough and non-trough groups was found with respect to clinical and functional outcomes (P > .05).Conclusion
The additional procedure of creating a trough did not improve clinical outcomes in terms of frank dislocation; however, at the final follow-up, patients with the trough showed less anterior apprehension. Overall, arthroscopic Bankart repair using suture anchors had relatively good clinical outcome, with a redislocation rate of 6.8%.Level of evidence

Objectives
Since 2012, we have routinely applied balloon protection of the proximal left subclavian artery to prevent embolic events through the left vertebral artery during debranching thoracic endovascular aortic repair. This study aimed to study the effectiveness of balloon protection of the proximal left subclavian artery.Methods
We reviewed the medical records of 157 patients who underwent debranching thoracic endovascular aortic repair between 2007 and 2017. Of these, 71 patients for whom balloon protection of the proximal left subclavian artery was used were assigned to the balloon protection of the proximal left subclavian artery group (58 men; age: 78 ± 6.7 years), and 86 patients were assigned to the control group (66 men; age: 78 ± 8.9 years). A total of 51 patients from each group were matched by their propensity scores to adjust for differences in the patients’ characteristics.Results
Perioperative stroke was significantly lower in the balloon protection of the proximal left subclavian artery group than in the control group (0%: 0/71 vs 7.9%: 7/86, P = .014). Freedom from all causes of mortality at 2 and 4 years was significantly higher in the balloon protection of the proximal left subclavian artery group compared with the control group (93%/76% vs 77%/59%, P = .015). Freedom from aortic death at 2 and 4 years was similar in both groups (97%/97% vs 91%/86%, P = .094). Propensity score matching yielded similar results of better freedom from all causes of mortality in the balloon protection of the proximal left subclavian artery group (93%/93% vs 81%/63%, P = .017) and equivalent aortic death in both groups (95%/95% vs 92%/88%, P = .30).Conclusions
Debranching thoracic endovascular aortic repair using balloon protection of the proximal left subclavian artery demonstrated more appropriate early and late outcomes. Evaluation using propensity score matching enhanced the efficacy of balloon protection of the proximal left subclavian artery. 相似文献17.

Objective
The purpose of this investigation was to determine our limb-related contemporary pediatric revascularization perioperative and follow-up outcomes after major blunt and penetrating trauma.Methods
A retrospective review was performed of a prospectively maintained pediatric trauma database spanning January 2010 to December 2017 to capture all level I trauma activations that resulted in a peripheral arterial revascularization procedure. All preoperative, intraoperative, and postoperative continuous variables are reported as a mean ± standard deviation; categorical variables are reported as a percentage of the population of interest.Results
During the study period, 1399 level I trauma activations occurred at a large-volume, urban children's hospital. The vascular surgery service was consulted in 2.6% (n = 36) of these cases for suspected vascular injury based on imaging or physical examination. Our study population included only patients who received an arterial revascularization, which was performed in 23 of the 36 consultations (1.6% of total traumas; median age, 11 years). These injuries were localized to the upper extremity in 60.9% (n = 14), lower extremity in 30.4% (n = 7), and neck in 8.7% (n = 2). The mean Injury Severity Score in the revascularized cohort was 14.0 (±7.6). Bone fractures were associated with 39.1% of the vascular injuries (90% of blunt injuries). Restoration of in-line flow was achieved by an endovascular solution in one patient and open surgery in the remainder, consisting of arterial bypass in 59.1% and direct repair in 40.9%. Within 30 days of the operation, we observed no deaths, no infections of the arterial reconstruction, and no major amputations. One patient required perioperative reintervention by the vascular team secondary to the development of a superficial seroma without evidence of graft involvement. Mean follow-up in our cohort was 43.3 (±35.4) months. During this phase, no additional deaths, amputations, chronic wounds, or limb length discrepancies were observed. All vascular repairs were patent, and all but one patient reported normal function of the affected limb at the latest clinic visit.Conclusions
Traumatic peripheral vascular injury is rare in the pediatric population but is often observed secondary to a penetrating force or after long bone fracture. However, contemporary perioperative and long-term outcomes after surgical revascularization are excellent as demonstrated in this institutional case series. 相似文献18.

Background
Incomplete and flawed national databases reveal strikingly inferior outcomes for rectal cancer patients resected at “low” versus “high “ volume hospitals, therefore, a study of outcomes of a “high” volume surgeon in a “low” volume Midwest community hospital setting examined this perception in comparison to contemporary studies.Methods
Review of 109 consecutive patients who underwent open resection of rectal cancer following neoadjuvant therapy, 1999–2010.Results
Despite the majority of tumors in the low rectum (54%), the rate of abdominoperineal resection was only 39% with R0 resection achieved in 94% and primary anastomosis in 61/109 patients (56%). Disease-free survival (DFS) 73%: stage 0 (complete response)- 100%, stage I- 88%, stage II- 68%, stage III- 50%, stage IV- 0% with recurrence rate of 11% (local recurrence (LR) - 3%, distant - 8%).Conclusion
Outcomes of rectal cancer resection by a “high” volume surgeon in a “low” volume Midwest community hospital setting were comparable to contemporary studies from tertiary care institutions. Geographic location and hospital capacity matter less than access to multispecialty expertise providing neoadjuvant therapy and following standard principles of oncologic resection, in efforts to optimize rectal cancer outcomes. 相似文献19.

Objective
To evaluate and compare the early outcomes of patients treated for complex aortic aneurysms using a commercially available Zenith fenestrated endograft (ZFEN) or an advanced customized fenestrated-branched endovascular repair, which includes custom-made device or off-the-shelf p-branch devices available for use in a physician-sponsored investigational device exemption (PSIDE).Methods
Between July 2012 and July 2015, patients who underwent to complex aortic aneurysms repair at University of North Carolina-Chapel Hill were retrospectively analyzed using data prospectively collected in electronically maintained aortic database. Patients were separated in two groups: ZFEN and PSIDE (custom-made device and p-branch). Demographics data, cardiac risk factors, comorbidities, computed tomography angiography anatomic measurements (aneurysm diameter, length of aortic coverage above the celiac artery), procedural data (operative time, estimated blood loss, intraoperative complications), and 30-day outcomes (mortality, major adverse cardiac events, stroke/transient ischemic attack, paraplegia, gastrointestinal complications, visceral branch complications, and endoleak) were analyzed.Results
Among the 131 repairs for complex aortic aneurysms (juxtarenal or thoracoabdominal), there were 60 ZFEN and 71 PSIDE devices. Demographics and risk factors had similar distribution between groups, except that PSIDE patients more commonly had a history of previous aortic surgery (33% vs 5% [ZFEN]; P = .0001). PSIDE patients had a greater number of stented vessels (3.4 vs 2.2; P < .001) and length of aortic coverage (72 mm vs ?13.4 mm) than ZFEN; however, no differences were seen in operative time, estimated blood loss or fluoroscopic time. Early outcomes were similar between groups, except for duration of hospital stay, which was significantly longer in PSIDE cohort (4.4 days vs 3.3 days; P = .05).Conclusions
More advanced fenestrated-branched endovascular repair does not seem to increase the complications associated with repair compared with patients receiving a ZFEN device in an experienced treatment center. Although mortality and morbidity were comparable between the groups, further studies evaluating long-term outcomes are needed. 相似文献20.
