Hemobilia: transcatheter occlusive therapy and long-term follow-up

Cardiovascular and Interventional Radiology
R UflackerS Lima

Abstract

Eight patients with life-threatening hemobilia were treated by percutaneous transcatheter occlusive therapy. The bleeding was caused by a traumatic pseudoaneurysm of the hepatic artery in 6 cases (auto accident in 4, surgery in 1, biliary drainage in 1) and a true aneurysm of the hepatic artery in 2 (unknown etiology in 1 and mycotic in 1). Arterial catheterization was used in all cases except for one in which a direct percutaneous puncture was performed. Gelfoam alone was used as embolic material in 3 patients. In 1 patient each, the material used was gelfoam plus coils, coils alone, blood clot, n-butyl-cyanoacrylate and an occluding balloon catheter. In all cases the bleeding stopped and did not recur during the follow-up period which ranged from 9 months to 14 years. This experience indicates that transcatheter occlusive therapy is an effective method for the treatment of severe hemobilia.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
