PURPOSE: To evaluate endovascular repair of abdominal aortic aneurysms (AAA) under local anesthesia in the acute setting. METHODS: Between 1998 and 2001, 47 patients with an acute AAA were evaluated for endovascular repair after informed consent, provided they were in a stable, albeit hypotensive condition. The patients underwent urgent computed tomography to assess suitability for endovascular repair; 16 were eligible for stent-graft repair: 9 were frank ruptures and 7 were symptomatic aneurysms. Complications and outcome of endovascular repair were evaluated; mortality was compared to a contemporaneous surgical cohort. RESULTS: Seven (23%) of 31 patients having a standard surgical procedure died in the study period compared to 1 (6%) of 16 patients undergoing endovascular repair (following conversion to surgery because of calcified access vessels). Twelve (75%) of the endovascular repairs were performed under local anesthesia; no complications with this mode of anesthesia were encountered. The median duration of the endovascular procedures was 110 minutes (range 75-240); median blood loss was 250 mL (range 100-2800 mL). Only 4 patients required blood transfusion, and only 8 patients required admission to the intensive care unit. There were 3 postoperative complications (1 ischemic colitis, 1 renal failure, 1 groin hematoma). During follow-up, 3 endograft patients received stent-graft extensions in uneventful procedures. Two patients died at 9 and 16 months from cardiac causes. CONCLUSIONS: This study demonstrates the feasibility and possible advantages of endovascular repair under local anesthesia in selected acute AAA patients. Further studies are needed to prove the advantages over open repair.
