Ruptured aneurysms of the internal iliac artery. Report of two cases.

Solitary internal iliac artery aneurysms are very rare. Their localisation deep in the pelvis makes diagnosis difficult. Therefore they are not detected until they reach a significant size and produce symptoms. These symptoms are due to compression on the adjacent structures or their rupture. Duplex scan, computerized tomography, and arteriography are the most useful diagnostic procedures. The correct surgical therapy consists of the ligature of the internal iliac artery and endoaneurysmorraphy with obliteration of the tributary branches. We report herein two cases of aneurysms of the internal iliac artery that made their clinical debut with signs of rupture.
