Spontaneous rupture of a left iliac arterial aneurysm. A case report.

Isolated aneurysm of the iliac arteries is rare. It represents only 1.7% of the aneurysms of the aortic bifurcation involving the arteries (7, 13) and its rupture can be fatal. It is located deep in the pelvis and it is often difficult to detect clinically. The symptoms can mimic genitourinary, gastrointestinal or neurologic disorders. Prompt diagnosis by computerized tomography must be made in cases of emergency. Urgent aneurysmectomy is indicated in case of rupture. The average mortality rate is 50%.
