Results of Open and Endovascular Repair of Complex Aortic, Iliac, and Femoral Anastomotic Aneurysms.

Abstract

Anastomotic aneurysms (AA) manifest as late complications of aortic-iliac-femoral reconstruction with a prosthetic graft. We studied open and endovascular repair of complex aortic iliac and femoral AA was performed for (A) Rupture, (B) Large symptomatic aneurysms, (C) Recurrent, (D) Femoral AA requiring simultaneous arterial reconstruction for critical limb ischemia in two teaching hospitals. Between 1990 and 2024, 100 aorto-femoral-iliac AA were repaired with 32 representing complex AA involving aorta (n = 6), iliac (n = 3), femoral (n = 23). Aortic and iliac anastomotic aneurysms underwent endovascular repairs in 5 patients and open repair in 4 patients with satisfactory outcomes in all. All 23 patients presenting with complex femoral anastomotic aneurysms were repaired via open technique, including five presenting with rupture with mortality in two, and one mortality among those presenting with large aneurysms. Complex femoral AA take longer to present after index operative, showed greater operative time, intra-operative blood loss but had similar mortality to patients with non-complex AAs. Most aortic and iliac AA can be repaired with endovascular and open techniques with satisfactory results, while complex femoral AA required open repair.
