[Isolated aneurysms of the internal iliac artery. A clinical contribution]

Five patients with isolated aneurysms of the internal iliac artery were identified and submitted to surgical procedure. Two patients were operated on in election, three in emergency with aneurysmatic rupture. The natural course of this pathology is one of progressive expansion and rupture. This lesion is often asymptomatic, but sometimes we found associated, compression symptoms of genito-urinary, intestinal tract and venous and neurological structures. Echography, CT scan and angiography are the most common and useful diagnostic procedure. Endoaneurysmectomy with proximal and distal suture of the stumps is the appropriate treatment in the majority of the cases.
