Abstract
Isolated aneurysms of the iliac arteries comprise less than 2% of abdominal aneurysms. The internal iliac artery is involved in 10-30% of cases. In most cases patients are asymptomatic, unless rupture occurs. They can be diagnosed by Doppler ultrasonography, magnetic resonance imaging or, preferably, angiotomography. Significant expansion, diameter of 3 cm or greater, and symptomatic cases are indications for surgery. We present the case of a patient with an incidental ultrasonographic finding of bilateral aneurysm of the internal iliac arteries, both with indications for surgery. The patient was successfully treated with endovascular techniques, first repairing the right internal iliac with a branched iliac stent graft, preserving patency, then embolizing the left internal iliac artery. Knowledge of the various different techniques and devices and their limitations is fundamental to adequate planning of endovascular treatment, even in rare cases.
