Purpose: This paper reviews our experience in endovascular treatment of isolated iliac artery aneurysms (IIAAs) with a large number of patients.
Materials and methods: From May 2005 to September 2013, 45 patients (43 men and two women; mean age, 74 ± 10 years) with a total of 59 IIAAs underwent endovascular treatment at our institute. We evaluated technical success, long-term patency, early and late complications and overall mortality. Patients were divided into two groups: emergency-treatment group and elective-treatment group.
Results: At a median follow-up of 34.3 months, we achieved a technical success of 97.8 %, a primary patency of 95.5 % and a secondary patency of 100 %, with complete exclusion of the aneurysm in 84.5 % of cases. The incidence of endoleaks was of 15.5 %: eight were type II and one was type III; perioperative mortality was 4.7 %.
Conclusions: Our study documents the effectiveness, in both emergency and elective settings, of the endovascular treatment of iliac aneurysms (EVIAR), which has become the first-choice treatment at our institute. In particular cases, it is also possible to avoid embolisation of the internal iliac artery.
