AIM: The aim of this study was to report our experience with endovascular repair of anastomotic aneurysms occurring after graft replacement for abdominal aortic aneurysms or aorto-iliac obstructive disease. METHODS: Between January 2000 and April 2006, 19 consecutive male patients (median age 73 years) underwent endovascular repair for 22 anastomotic aneurysms [proximal aortic (n=15), iliac (n=4), concomitant aortic and iliac (n=3)], occurring 3 months to 18 years (mean 8.6 years) after open surgery. Three patients (15.7%) underwent emergency treatment for rupture. No patient had symptoms or positive blood tests for infection of the original graft. Twelve patients were treated with a bifurcated stent-graft, 4 patients with a proximal stent-graft cuff, 2 patients with a tube iliac stent-graft, and 1 patient with a mono-iliac stent-graft. RESULTS: Stent-grafts were successfully deployed in all patients. Procedure-related complications or death were not observed; open conversion was never required. Median hospitalisation was 9 days (range 3-45). During a median follow-up of 16 Euro-months (range, 2-44) all anastomotic aneurysms maintained excluded: 4 patients (21%) died. We observed 1 major complication (5.2%): an iliac branch occlusion occurred 1 month after the procedure, successfully treated with catheter-directed thrombolysis. Overall, survival rates at 6, 12, 18 and 36-months were 92.8%, 84.4%, 72.3%, and 57.8% respectively. CONCLUSION: Our experience confirms that endovascular stent-grafts can be used successfully to exclude anastomotic aortic aneurysms after open surgery. Endovascular repair seems to be effective at mid-term follow-up.
