Simultaneous Surgical Treatment of Abdominal Aortic Aneurysm and Bilateral Aneurysms of the Internal Iliac Artery

Abstract

Introduction: The purpose of this study is to present our experience in the management of patients with abdominal aortic aneurysms (AaA) and aneurysms in both the internal iliac arteries (IIA) at the same time. Methods: Between 2000 and 2005, a series of 13 patients with AAA and also aneurysms in both the IIA, were treated in our clinic. They were all men with a mean age of 74 years. The size of the IIA aneurysms (IIAA) ranged from 2.0 to 8.0 cm (mean, 3.4 cm). All patients underwent an aneurysmatectomy of the AAA and placement of a prosthetic bifurcated aorto-biiliac or-bifemoral bypass, by a transperitoneal approach. The management of one of the two IIAA was the aneurysmatectomy and the direct revascularization of the healthy peripheral portion of the remaining IIA with the ipsilateral leg of the aorto-biiliac bypass. The other IIAA was treated with proximal ligation of its neck and aneurys-morraphy.

Results: No patient died during the first 30 postoperative days. Morbidity was about 7.7% (one patient suffered from ‘trash foot’, which was treated successfully with conservative measures). Finally, the mean stay in hospital was 7 days and no patient clinically presented symptoms of pelvic or colonic ischaemia.

Conclusions: Simultaneous treatment of AAA and bilateral IIA aneurysms is a technically difficult, but safe procedure, if it is performed meticulously. Revascularization of at least one internal iliac artery is strongly recommended in order to avoid dangerous complications, such as pelvic or colonic ischaemia.
