Predominant blood supply to the supraduodenal bile duct is derived from
Blood supply of supraduodenal bile duct Axial Blood supply: (98%) The most impoant of these vessels run along the lateral borders of the bile duct and are called the &;3 o clock &; and &;9 o clock&; aeries. 60% of the blood supply occurs from the duodenal (caudal) end of the duct primarily from branches of the retroduodenal aery (posterior superior pancreaticoduodenal aery). 38% of the blood supply occurs from the hepatic (cephalic) end of the right hepatic aery. Non-axial blood supply: only 2% of blood supply to the supraduodenal bile duct from the branches of the hepatic aery proper. Ref: Gray&;s Anatomy 41st edition Pgno: 1176
