Background: There is an increasing demand for living donor liver transplants. However, the biliary complication rates are still high. Methods: The anatomy of the communicating arcade (CA) between the right and left livers and its relevance to the blood supply of the hilar bile duct was evaluated using adult cadaveric livers and cast specimens. Results: In all specimens that were of sufficient quality for evaluation, th CA was found to be located extrahepatically in the hilar plate with thin tributaries branching to the hilar bile duct. On the left side, 55% of the CA originated from a segment IV artery. On the right side, 73% of the CA originated from the right anterior hepatic artery. Conclusions: To maintain an adequate blood supply for the hilar bile duct of the donor graft during living donor liver transplantation, the branching point of the CA should be preserved.
