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
