title: Arterial vascularisation of the extrahepatic biliary tract.
abstract: The aim of this study was to establish a plan of the arterial distribution to the main supraduodenal biliary tract in order to draw practical conclusions for biliary surgery, especially in bilio-alimentary and bilio-biliary anastomoses and liver transplantation. It was based on a study of 60 fresh subjects and was carried out using four different methods: dissection after injection of colored latex into the superior mesenteric a. (10 subjects), radiography and dissection after injection of Micropaque into the celiac trunk (10), dissection after injection of Indian ink into the common hepatic a. (10) and radiography and dissection after selective injection of the right hepatic a. or the gastroduodenal a. (30). Analysis of the results leads to definition of three types of vascularisation and two territories, superior and inferior, overlapping at the level of the mouth of the cystic duct. The practical implications for biliary surgery and liver transplantation are discussed.
