Long-term efficacy of endovascular treatment of isolated iliac artery aneurysms [Efficacia a lungo termine del trattamento endovascolare di aneurismi isolati dell'asse arterioso iliaco]

Purpose: The aim of this study was to evaluate the efficacy of endovascular treatment of isolated iliac artery aneurysms (IIAA) and compare our data with those reported in the literature. Materials and methods: From May 2005 to December 2010, 32 patients (31 men and one woman; mean age 73±12 years) with a total of 40 IIAAs underwent endovascular treatment at our institute. We evaluated technical success, long-term patency, early and late complications and overall mortality. Results: At a median follow-up of 36 months, we achieved a technical success of 100%, a primary patency of 95% and a secondary patency of 100%, with complete exclusion of the aneurysm in 84.6% of cases. In 12.8% of cases, there was a reduction in aneurysm sac volume, with an incidence of type II endoleak of 12.8%. Overall survival at 1, 2, 3, and 6 years was 96.8%, 84.2%, 66.6% and 64%, respectively. Conclusions: Our study documents the effectiveness of endovascular treatment of iliac aneurysms, which has become the first-choice treatment at our institute. This finding is consistent with the most recent literature and confirms the safety and long-term patency of stent-graft placement. © 2012 Springer-Verlag Italia.
