Leaking hepatic artery aneurysm successfully treated with covered stent.

Hepatic artery aneurysm (HAA) is rare with reported incidence of 0.02%. It accounts for approximately 12-20% of all visceral aneurysms. The reported risk of rupture ranges from 14% to 80% of all HAAs. Traditionally, HAA has been treated surgically or by transcatheter coil embolization. There are few published reports of percutaneous HAA stenting. We report a case of a 72-year-old female with leaking HAA who was successfully treated with endovascular stenting. The authors include a review of the relevant literature. 2009 Wiley-Liss, Inc.
