Short to midterm results of endovascular for 105 case of infrarenal abdominal aortic aneurysms / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To assess short to midterm outcome of endovascular aneurysm repair (EVAR) of infrarenal abdominal aortic aneurysms (AAA) in 105 cases.</p><p><b>METHODS</b>Stent-grafts were placed into 105 patients with infrarenal AAA between January 2001 and February 2007. The clinical data of those cases were retrospectively analyzed.</p><p><b>RESULTS</b>Primary technical success rate was 100%. Eighty-two cases (78.09%) were followed-up for 1 to 73 months (mean, 8.9 +/- 5.8 months). Three cases (2.86%) died during peri-operative period, from acute cardiac infarction, multi-organ failure and significant upper gastrointestinal bleeding, respectively. Another one died from hepatic cancer 30 months after EVAR. Twenty-one cases experienced primary endoleak. Eighteen were type I, among which 10 underwent secondary intervention in the form of balloon dilatation (n = 9) and stent-graft placement (n = 1), 8 sealed spontaneously. Two cases were type II and sealed spontaneously. One type III was treated by placing a stent-graft. An emergent femorofemoral crossover was performed for one graft limb thrombosis 2 weeks after EVAR. Four late type I endoleaks occurred. One stent-graft migration without endoleak was cured conservatively. Two stent-graft infections occurred 1 month and 3 months after EVAR respectively, and were cured with debridement, drainage and antibiotics. Nine femorofemoral or iliofemoral bypass and three internal iliac bypasses were all patent during the follow-up period.</p><p><b>CONCLUSION</b>Endovascular repair is a safe and effective method for infrarenal AAA with perfect short to midterm outcomes.</p>
