BACKGROUND: Open repair of para-anastomotic aneurysms (pAAA) after conventional aortoiliac repair is associated with a high perioperative mortality and morbidity. Endovascular treatment options have evolved over the last decade. The aim of this article is to demonstrate and review these endovascular strategies. MATERIAL AND METHODS: Between 01/2009 and 06/2012, a total of 12 patients received endovascular treatment for proximal (n = 7) or distal (n = 5) pAAA (n = 2 contained rupture). A retrospective analysis of these patients was performed. Median age was 71.5 years (range 55-87 years). The median time interval between primary operation and endovascular repair of the pAAA was 15 years (range 1-31 years) and median follow-up was 1.3 years (range 0 days - 3 years). Endovascular exclusion of the pAAA was achieved by implantation of an aortouniiliac endograft (n = 6), chimney graft (n = 1), fenestrated endograft (n = 2) and iliac extension (n = 3). RESULTS: Technical success could be achieved in all patients and in-hospital mortality was 16.8 % (n = 2). No patient required a reintervention but during follow-up one additional patient died due to gastrointestinal bleeding. No primary or secondary type I/III endoleaks were observed. CONCLUSIONS: Despite a not negligible mortality rate endovascular treatment of para-anastomotic aneurysms and anastomotic pseudoaneurysms appears to be a safe alternative for conventional open repair.
