BOMBIN F, JUAN. Results of surgical treatment of aneurysms of the aorto iliac segment: Review of 90 patients. Rev Chil Cir [online]. 2010, vol.62, n.2, pp.150-159. ISSN 0718-4026.

Background: Abdominal aorta is the most common site for the formation of degenerative aneurysms. which remain asymptomatic until they rupture. Aim: To review the results of surgical treatment of aorto iliac segment aneurysms. Material and Methods: Retrospective review of medical records of 90 patients aged 48 to 88 years (60 males), operated for aneurysms of the aorto iliac segment, between 1998 and 2008. Patients were followed for a mean of 40 months. Results: Eighty six patients had infrarenal aneurysms with or without iliac extension and four had puré iliac aneurysms. Four patients had inflammatory aneurysms Eighty five were treated with open surgery. Of these, nine had ruptured or fissured aneurysms, two had lower limb ischemia, one had an extrinsic compression and one a complete thrombosis of the aneurysm. Five patients, without complications, were subjected to an endovascular repair. Overall 30 days mortality was 4.4%. The figures for ruptured and uncomplicated aneurysms were 11.1 and 2.7% respective ly. No patient subjected to endovascular repair died. One, two and three years survival rates were 90, 79 and 78% respectively. No patient died due to complications of the prosthetic graft. Three patients required an early re-intervention (an embolectomy in one and for a femoro-femoral bridge in two). Nine patients required a late re-intervention (an intestinal obstruction due to adherences in one and incisional hernias in eight). No patient subjected to endovascular repair required a re-intervention. Conclusions: Surgery for aorto iliac segment aneurysms is safe and avoids deaths caused by their complications.
