Clinical impact of hypogastric artery occlusion in endovascular aneurysm repair

PurposeTo report the long-term results for patients treated with endovascular aneurysm repair and additional embolization and coverage of the hypogastric artery compared with patients treated with simple endovascular aneurysm repair.MethodsA database of our endovascular aneurysm repair patient cohort was reviewed to find patients with iliac artery aneurysms. The baseline characteristics, the procedural data and the results for patients treated with endovascular aneurysm repair and concomitant hypogastric artery embolization were compared with those for patients treated with simple endovascular aneurysm repair. The results were analyzed for significant differences.ResultsOf 106 endovascular aneurysm repair patients treated at our vascular unit from 2001 to 2010, 24 had undergone additional hypogastric artery embolization. The complication rate was significantly increased in this group (12.5% vs. 2.4%; p = 0.041), and the long-term results were significantly poorer. Additional hypogastric artery embolizatio...
