To report a retrospective evaluation of the efficacy and midterm clinical results of the Anaconda stent-graft in the endovascular repair of infrarenal abdominal aortic aneurysms.

Fifty-one patients (48 men; mean age 71±8 years, range 62–89) were treated with the Anaconda stent-graft from January 2006 to September 2007. Six patients were considered at high risk for open repair (defined as ASA grade 3) and 10 had undergone previous laparotomy. The mean neck diameter and length were 26 mm (range 22–30) and 18.5 mm (range 14–35), respectively. Mean proximal neck angulation was 30° (range 5–60). Severe iliac artery tortuosity (>60°) was seen in 20 (39%) patients; 3 (6%) had a proximal aneurysm neck angle >45°.

The technical success rate was 100%; intraprocedurally, 7 (14%) stent-grafts were repositioned to address renal artery occlusion by the graft (n=1) or type I endoleak …
