Bilateral ruptured isolated internal iliac artery aneurysms--report of a case and review of the literature.

We present herein, a rare case of a 78-year-old man who experienced rupture of an isolated internal iliac artery aneurysm on 2 separate occasions. He underwent successful embolization with ligation of the right aneurysm at our institution, where only 2 such cases have ever been seen. Embolization with ligation proved very effective in clotting the intraaneurysmal blood in this case and would appear to be the treatment of choice for very large aneurysms. A review of the English and Japanese literature follows this case report.
