THERAPEUTIC EMBOLIZATION OF POSTCHOLECYSTECTOMY HEPATIC-ARTERY ANEURYSM

A "sandwich" technique employing steel coils and gelfoam embolization was applied in two cases of hepatic artery aneurysms. Immediate cessation of the bleeding was evident clinically and the post-embolization angiogram showed occlusion of the vascular lesion. Cholecystectomy is one of the most common abdominal operations and it is generally well tolerated particularly in young and middle-aged patients. Morbidity rates of 5 % to 32 % and mortality rates of 0.4 % to 2.5 % have been reported, depending on such factors as age, underlying illness, etc. (1-4). The most frequent complications of cholecystectomy are wound infection, abscess, ductal injury or ligation, and bleeding. This paper describes two cases of hepatic pseudoaneurysm following iatrogenic damage during cholecystectomy which was treated with transarterial embolization.
