Open in a separate window OBJECTIVESAlthough commercial iliac branch devices offer a new and valid endovascular approach to treating iliac aneurysm and effectively preserve antegrade flow of the internal iliac artery, their use may not be suited for all types of challenging anatomy, especially isolated common iliac artery aneurysm. Our custom-made iliac bifurcation device has a unique design and excludes both combined and isolated iliac branch aneurysm. This study validated the efficacy and safety of the custom device by comparing clinical outcomes between groups receiving commercial and custom devices.METHODSData of consecutive patients receiving iliac bifurcation device implantation for iliac aneurysm with or without concomitant endovascular repair for abdominal aortic aneurysm from January 2010 to May 2019 were reviewed.RESULTSIliac bifurcation device implantation with or without concomitant abdominal aortic aneurysm stent grafting was completed in 46 patients (commercial, n = 35; custom, n = 11). No significant differences were observed regarding postoperative complications, occlusion or endoleak. Comparisons of primary (80.8% vs 85.7%, P = 0.88) and secondary (86.5% vs 85.7%, P = 0.85) patency and freedom from reintervention (88.2% vs 100%, P = 0.33), all-cause mortality (78.6% vs 100%, P = 0.25) and aneurysm-related mortality (100% vs 100%, P = 1.00) also indicated no differences at a 5-year surveillance point. Furthermore, the iliac aneurysms of the groups displayed similar shrinkage 1 year after procedures.CONCLUSIONSFor iliac aneurysm, the novel custom-made iliac bifurcation device is an adaptable design not inferior to commercial devices with regard to postoperative complications, bridge occlusion, endoleak and short-term aneurysm remodelling. It provides an alternative for treatment, particularly when certain anatomic challenges are present.Clinical trial registration2018-07-050BC, 2017-01-023ACF. 相似文献

The aim of this retrospective study was to evaluate the technique for iliac artery reconstruction in abdominal aortic aneurysm repair, when external and internal iliac arteries were required to reconstruct individually. Among 203 elective infrarenal abdominal aortic aneurysm repairs, 22 patients (10.8%) required individual reconstruction of bilateral or unilateral iliac arteries, including 56 external or internal iliac arteries. Mainly, three types of procedures were performed: (1) the external iliac artery was anastomosed to the end of the bifurcated graft limb in an end-to-end manner, and the internal iliac artery was attached to the side of the external iliac artery, (2) the external iliac artery was anastomosed to the end of the bifurcated graft limb in an end-to-end manner and the internal iliac artery was bypassed with the use of a straight prosthetic graft extending from the limb of the bifurcated graft, and (3) the internal iliac artery was anastomosed to the end of the bifurcated graft limb in an end-to-end fashion, and the external iliac artery was sewn to the side of the graft limb. In these three types of procedures, the third technique was the easiest and simplest anatomically. 相似文献

BACKGROUND: To study the long-term outcomes after exclusion of internal iliac arterial aneurysm performed concomitantly with abdominal aortic aneurysm repair in patients with ruptured aortic aneurysm or other high-risk conditions. METHODS: The 31 patients who participated in this study underwent emergency (N = 9) or elective surgery (N = 22). The abdominal aortic aneurysm and the common iliac artery were excluded together with the internal iliac aneurysm in 7 patients. Forty-three (12 bilateral and 19 unilateral) internal iliac aneurysms were excluded: 35 by proximal ligation only, 5 by proximal and distal ligation, and 3 by partial resection of the proximal part of the aneurysm. The platelet count and fibrinogen level were evaluated pre- and postoperatively. Pelvic organ ischemia, classed as ischemic colitis, buttock claudication and sexual dysfunction, was examined. RESULTS: The inferior mesenteric artery was reimplanted in 21 patients. The platelet count dropped significantly postoperatively, but the fibrinogen level increased and no bleeding tendency was noted. Ischemic colitis occurred in 7 patients, resulting in colonic infarction in 2 patients. The operative mortality was 16%, and the postoperative observation periods ranged from 4 days to 217 months (mean, 60 months). The incidence of buttock claudication and sexual dysfunction was 12% and 39%, respectively. The excluded aneurysms were all thrombosed at discharge, and no late rupture was noted. The 5- and 10-year survival rate after surgery was 56% and 51%, respectively. CONCLUSIONS: Exclusion of the internal iliac aneurysm concomitant with abdominal aortic aneurysm repair shows acceptable outcome when performed in patients with high-risk conditions. 相似文献

Extra-anatomic revascularization and aortic exclusion for mycotic aneurysms of the infrarenal aorta and iliac arteries in an Asian population 总被引:1,自引:0,他引:1
OBJECTIVES: To study the clinical presentation, management and eventual outcome of patients with mycotic abdominal aortic aneurysms managed with aortic exclusion and extra-anatomic reconstruction. DESIGN: A retrospective chart review of 18 cases treated at a single institution. METHODS: Medical records of 18 patients admitted to our institution from October 1997 to July 2006 with a diagnosis of mycotic abdominal aortic aneurysms were reviewed. In all cases, the diagnosis was confirmed by abdominal computed tomography and empirical parenteral antibiotics were administered. Seventeen patients had surgical debridement, aneurysm exclusion, and extra-anatomic reconstruction. The antibiotics were continued in the postoperative period for 6 weeks. RESULTS: Immunosuppression was present in 72%, with diabetes mellitus present in 56%. Salmonella sp was the causative organism in 72% of cases. Most patients presented late, with a 67% incidence of contained rupture. Seventy-two percent needed early or emergency surgery with less than 1 week of preoperative antibiotics. Disease-specific mortality was 39% (7/18). There was 1 late death during the mean follow-up period of 34 +/- 26 months. One patient with an infrarenal aneurysm arising relatively close (neck, 2 cm) to the renal arteries died on table when proximal ligatures cut through the friable aortic wall, resulting in uncontrollable exsanguination. One third of patients on long-term graft surveillance developed mild to moderate stenosis at the anastomotic site. CONCLUSIONS: Empirical antibiotics must be started early, aiming to achieve 1 week of antibiotics prior to surgery. In the Asian population, 3 characteristics are apparent: (1) most patients are immunocompromised; (2) patients present late in the course of disease; and (3) Salmonella is usually responsible. Extra-anatomic bypass may provide a safe option for revascularization of mycotic aneurysms of the iliac arteries and infrarenal aorta. 相似文献

BACKGROUND: Isolated iliac artery aneurysms (IAA) in patients with or without previous abdominal aortic aneurysm (AAA) repair are rare. We wanted to compare the presentation, distribution, treatment, outcome and patterns of subsequent aneurysm formation in these patients. METHODS: We retrospectively reviewed patients with isolated IAA over a 10-year period. Patients with primary isolated IAA (group 1) were compared with patients who presented with IAA after previous AAA repair (group 2). RESULTS: There were 23 patients in each group. Demographics and comorbidities were similar. No aneurysms were detected outside of the iliac system in group 1; 22% of patients in group 2 had other aneurysms. The mean time after AAA repair to IAA diagnosis was 8.8 +/- 3.2 years for operated on patients. The in-hospital mortality was 0% for elective cases and 50% for emergency cases for both groups. Three patients in group 2 (13%) developed new aneurysms during follow-up, whereas the only new aneurysm in group 1 was a contralateral IAA. CONCLUSIONS: Patients with new IAA after AAA repair have a greater tendency to develop further aneurysms in other sites, synchronously or metachronously. The time to detection of new IAA after AAA repair is at least 5 years in most cases. In both groups, a quarter to a third of patients present with rupture, with a resultant mortality of 30% to 50%, whereas those operated on electively have minimal morbidity and almost no mortality. 相似文献

Today, repair of an abdominal aortic aneurysm with interposition prosthetic graft replacement is the only reliable method of preventing aneurysm rupture. The Mayo experience demonstrates that this repair also can be accomplished in high-risk patients with very acceptable morbidity and low mortality rates. However, it must be emphasized that these results are related not only to the surgical procedure itself but also to vigorous perioperative medical support, including intraoperative pharmacologic enhancement of cardiac function, intra-aortic balloon counterpulsation if necessary, and intensive postoperative pulmonary management. When resources are available for intensive intraoperative and postoperative support, direct graft repair is the treatment of choice for high-risk patients with abdominal aortic aneurysms. 相似文献

PURPOSE: To determine the relative rates of common iliac artery (CIA) expansion after elective straight aortic tube-graft replacement of infrarenal abdominal aortic aneurysms (AAA). METHODS: Five participating centers in this 2004 study entered patients they had managed by an aortoaortic tube graft for elective AAA repair. The procedures took place between January 1995 and December 2003. Postoperative computed tomography (CT) scans were obtained for all patients in 2004 to assess changes in CIA diameter. Measurements on preoperative and postoperative CT scans were all made at the same level using the same technique. RESULTS: Entered in the study were 147 patients (138 men, 9 women) with a mean age of 68 years. Mean follow-up from aortic surgery to verification of CIA diameter on the postoperative CT scan was 4.8 years. Mean preoperative CIA diameter was 13.6 mm vs 15.2 mm postoperatively. No patient developed occlusive iliac artery disease during follow-up. Three patients (2%) required repeat surgery during follow-up for a CIA aneurysm. The 147 patients were divided into three groups based on preoperative CIA diameter shown in CT scan: group A (n = 59, 40.1%), both CIA were of normal diameter; group B (n = 53, 36.1%), ectasia (diameter between 12 and 18 mm) of at least one CIA; group C (n = 35, 23.8%), an aneurysm (diameter >18 mm) of at least one CIA. CIA diameter increased by a mean of 1 mm (9.4%) over 5.5 years in group A vs 1.7 mm (12.1%) over 4.3 years in group B and 2.3 mm (12.7%) over 4.2 years in group C. The three patients who required repeat surgery for a CIA aneurysm during follow-up were all in group C. Four variables were associated with aneurysmal change in CIA: initial CIA diameter, celiac aorta diameter on the preoperative CT scan, a coexisting aneurysm site, and the follow-up duration. CONCLUSIONS: Tube-graft placement during AAA surgery is justified even for moderate CIA dilatation (<18 mm). CIA aneurysms with a preoperative diameter > or =25 mm enlarge more rapidly and warrant insertion of a bifurcated graft during the same surgical session as AAA repair. The evolutive potential of CIA between 18 mm and 25 mm in diameter justifies a bifurcated graft when the celiac aorta diameter is >25 mm or the patient's life expectancy is > or =8 years. 相似文献

AIM: The aim of this study was to report our experience with endovascular repair of anastomotic aneurysms occurring after graft replacement for abdominal aortic aneurysms or aorto-iliac obstructive disease. METHODS: Between January 2000 and April 2006, 19 consecutive male patients (median age 73 years) underwent endovascular repair for 22 anastomotic aneurysms [proximal aortic (n=15), iliac (n=4), concomitant aortic and iliac (n=3)], occurring 3 months to 18 years (mean 8.6 years) after open surgery. Three patients (15.7%) underwent emergency treatment for rupture. No patient had symptoms or positive blood tests for infection of the original graft. Twelve patients were treated with a bifurcated stent-graft, 4 patients with a proximal stent-graft cuff, 2 patients with a tube iliac stent-graft, and 1 patient with a mono-iliac stent-graft. RESULTS: Stent-grafts were successfully deployed in all patients. Procedure-related complications or death were not observed; open conversion was never required. Median hospitalisation was 9 days (range 3-45). During a median follow-up of 16 Euro-months (range, 2-44) all anastomotic aneurysms maintained excluded: 4 patients (21%) died. We observed 1 major complication (5.2%): an iliac branch occlusion occurred 1 month after the procedure, successfully treated with catheter-directed thrombolysis. Overall, survival rates at 6, 12, 18 and 36-months were 92.8%, 84.4%, 72.3%, and 57.8% respectively. CONCLUSION: Our experience confirms that endovascular stent-grafts can be used successfully to exclude anastomotic aortic aneurysms after open surgery. Endovascular repair seems to be effective at mid-term follow-up. 相似文献

HYPOTHESIS: Supplemental oxygen can reduce intimal hyperplasia (IH) after stent deployment in a rabbit model. BACKGROUND: Endovascular stent placement is technically feasible, but long-term durability in vessels outside the aortoiliac system is compromised with postinterventional IH, which causes restenosis and failure of the arterial conduit. METHODS: Groups (n = 4 to 6) of female New Zealand white rabbits underwent placement of a 3-mm intraaortic stent with laparotomy and were placed in either normoxic (21% inspired oxygen concentration) or supplemental-oxygen (40% inspired oxygen concentration) environments for 0, 7, 14, and 28 days. The transarterial wall oxygen gradient was measured at 0, 7, and 28 days with an oxygen microelectrode. 5-Bromo-2'deoxyuridine (BrdU) was injected into the peritoneum before death to assess cellular proliferation. Aortic specimens were harvested en bloc and sectioned for analysis of cellular proliferation and intimal thickness. RESULTS: Intraaortic stent placement significantly decreased the transarterial wall oxygen gradient in the outer 70% of the vessel wall and was easily reversed at 7, 14, and 28 days with application of supplemental oxygen. Cellular proliferation was significantly decreased at 14 days (0.5% +/- 0.001% versus 2.3% +/- 0.002%; P <.001) and 28 days (0.4% +/- 0.001% versus 1.0% +/- 0.001%; P <.025) as measured with count of nuclei staining for 5-Bromo-2'deoxyuridine in the intima and media. Intimal thickness was significantly decreased at 28 days in oxygen-supplemented rabbits (intimal area/medial area = 0.50 +/- 0.07) as compared with controls (intimal area/medial area = 0.89 +/- 0.11; P <.025). CONCLUSION: This study shows the ability of supplemental oxygen to reverse arterial wall hypoxia, decrease cellular proliferation, and control IH at the deployment site of an intraarterial stent in a rabbit model. Forty-percent supplemental oxygen suppresses IH by 44% at 28 days as compared with normoxic control values. Cellular proliferation is reduced four-fold at 14 days and two-fold at 28 days in oxygen-supplemented rabbits as compared with control media after deployment. The clinical implications of these findings are significant, especially as the role of endovascular interventions continues to expand. 相似文献

This is a report of a patient presenting with a contained rupture of an internal iliac aneurysm following proximal ligation after abdominal aortic aneurysm repair three years earlier. The patient presented with a large pelvic mass with symptoms of urgency, frequency, dysuria, tenesmus and fevers associated with anemia. Following evacuation of the aneurysm and direct suture ligation of the distal branches of the internal iliac artery, the patient's aortic graft was covered with omentum which also filled the pelvic cavity. The importance of proximal and distal control of aneurysms and/or the importance of complete luminal control of internal iliac artery aneurysms is emphasized by this case. 相似文献

OBJECTIVE: To present our initial experience with the Zenith bifurcated iliac side branch device that preserves internal iliac artery flow whilst excluding aorto-iliac aneurysms. METHODS: Between November 2005 and October 2006, data was prospectively collected on 8 patients in whom this device was used; 2 aorto-bi-iliac aneurysms, 3 aorto-uni-iliac aneurysms, 1 solitary common iliac aneurysm, 1 distal type 1 endoleak, and 1 internal iliac aneurysm. RESULTS: No mortality or major complications resulted from use of this device. The median fluoroscopy time was 53 minutes (range 38 to 105) and a median of 102 g of iodine (range 84 to 130) as contrast were used. One patient required a blood transfusion and only one of the eight side branches occluded. There has been no endoleak related to the device in the median follow-up period of 6 months (1 to 14 months). CONCLUSION: This device provides an alternative for the management of patients with aorto-iliac aneurysms that is safe and less complex than, previously described, hybrid procedures that preserve internal iliac flow. 相似文献

In an attempt to define the preoperative risk factors that predictably influence mortality after aneurysmectomy, this study
reviews the surgical management of abdominal aortic aneurysms in a series of 110 consecutive patients who underwent elective
resection. The preoperative risks to be added to the present study included pulmonary insufficiency, renal dysfunction, advanced
age of over 80 years, ischemic heart disease, and associated other diseases such as thoracic aneurysms, atherosclerosis of
the limbs and malignant tumors. Forty-six patients had one of these risk factors (one-risk group), 17 had two (two-risk group),
and 9 had three (three-risk group). The operative mortality rates were 4.2 per cent for the high-risk patients and 0 per cent
for the patients at no risk. As the number of risk factors increased, aneurysm repair was associated with an increased operative
mortality; being 2.2 per cent in the one-risk group, 5.9 per cent in the two-risk group and 11.1 per cent in the three-risk
group. The common risk factor in patients who died after aneurysmectomy was pulmonary insufficiency which induced prolonged
periods of assisted ventilation. Thus, the optimal management of high-risk patients, particularly those with pulmonary insufficiency,
may reduce the mortality after aneurysmectomy.

Appropriate preoperative vascular assessment of patients presenting with aortic aneurysms and arterial occlusive disease is essential to obtain the optimal results from aneurysm repair. The renal arteries should be evaluated in patients with hypertension or renal dysfunction, and stenosis must be addressed when seen on arteriograms. Hemodynamically significant lesions are candidates for bypass concomitant with aortic replacement. The stump pressure of a patent inferior mesenteric artery should be assessed intraoperatively, and bypass or reimplantation should be performed if colon ischemia might result from internal mesenteric artery ligation. If vasculogenic impotence is suggested by preoperative studies, meticulous nerve-sparing dissection and revascularization of the internal iliac arteries may result in recovery of erectile function in some patients. In all cases of aneurysm repair, the hypogastric circulation must be maintained through either direct revascularization or bypass to major collateral arteries. Iliac occlusive disease may be evaluated with several modalities, including physical examination, noninvasive laboratory testing, arteriography, and the papaverine test, to determine whether critical or subcritical stenoses are present. Aortic bifurcation grafts should be used to construct the distal anastomoses beyond areas of significant disease. The extent of lower-extremity occlusive disease directly affects the long-term patency of aortic replacement, and diligent follow-up is necessary for timely intervention to maintain patency of vascular reconstructions. 相似文献

Case report of common iliac arteriovenous fistula associated with ruptured abdominal aortic aneurysm
Arai T Tachikawa M Matsuda Y Yamada M Shimizu K Inoue H Okuda Y 《Masui. The Japanese journal of anesthesiology》2006,55(10):1263-1265
We report a case of a 78-years-old woman with common iliac arteriovenous fistula associated with ruptured abdominal aortic aneurysm. Common iliac arteriovenous fistula was diagnosed preoperatively by CT. Anesthesia was induced with propofol and vecuronium and maintained with sevoflurane 2-3% in oxygen. Anesthesia was managed successfully monitoring hemodynamic state including central venous pressure and compensating of blood loss by autotransfusion. The patient underwent successful abdominal aortic replacement with uneventful postoperative course without any complications. 相似文献
