Comparison between endovascular repair and open surgery for isolated iliac artery aneurysms.

Purpose: This study was performed to compare endovascular repair with conventional open repair of isolated iliac artery aneurysms (IAAs). Methods: We retrospectively reviewed the charts of all patients who underwent repair of isolated IAAs between January 2008 and June 2012. Patients with infected, mycotic and ruptured iliac aneurysms and those with concurrent infrarenal abdominal aortic aneurysms greater than 30 mm in diameter were excluded from this analysis. Results: A total of 32 patients were treated with isolated IAAs. There were 20 open and 12 endovascular repairs. A comparison of the length of the operation (238 ± 84 min in the open group vs 176 ± 72 min in the endovascular group, P = 0.03) and intraoperative blood loss (1,735 ± 1,177 ml in the open group vs 503 ± 711 ml in the endovascular group, P = 0.01), revealed significant differences in favor of the endovascular procedure. Postoperative complications were less common in the endovascular group, although the difference did not reach statistical significance. Conclusions: The management of isolated IAAs with both endovascular and open repair can be accomplished with very low morbidity rates. Therefore, endovascular repair can be considered an alternative treatment for isolated IAAs. [ABSTRACT FROM AUTHOR]
