[Short to midterm results of endovascular for 105 case of infrarenal abdominal aortic aneurysms].
OBJECTIVE
To assess short to midterm outcome of endovascular aneurysm repair (EVAR) of infrarenal abdominal aortic aneurysms (AAA) in 105 cases.


METHODS
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.


RESULTS
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.


CONCLUSIONS
Endovascular repair is a safe and effective method for infrarenal AAA with perfect short to midterm outcomes.
