Different types of vascularizaton of supraduodenal biliary tract. [A] Axial type with single arch along the left border of bile duct. [B] Axial type with two arches along the right and left borders of the bile duct The arches are formed by posterior superior pancreaticoduodenal artery (PSPDA) from below and by right hepatic artery (RHA) and cystic artery from above. [C] Single Ladder type along the left border. Small horizontally directed branches arising from RHA, proper hepatic artery (PHA), gastroduodenal artery (GDA), and supraduodenal artery supply the bile duct. [D] Ladder type, Two ladders along the right and left borders of the bile duct. [E] Mixed type, Ladder type along the left border and axial type with single arch along the right border. CHA = Common hepatic artery; LHA = Left hepatic artery; RHA = Right hepatic artery; MHA = Middle hepatic artery; GDA = Gastroduodenal artery; PSPDA = Posterior superior pancreaticoduodenal artery.
