[Biliary hemorrhage due to a false aneurysm of the hepatic and gastroduodenal arteries (author's transl)].

Two cases of biliary hemorrhage due to false aneurysms are presented, one on an abnormal hepatic artery, the other on the gastroduodenal artery. Half of the cases of biliary hemorrhage have an intrahepatic etiology. Extrahepatic cases are equally divided between the main biliary duct and the gallbladder. Among the diagnostic investigations most authors agree on the choice of selective arteriography of the coeliac trunk. Controle of intrahepatic biliary bleeding can be obtained by partial hepatectomy or by ligation of the hepatic artery which is well tolerated. Treatment of extrahepatic bleeding is more diverse and takes into account both anatomical and surgical possibilities.
