Abstract: The classical method for arterial reconstruction in pediatric living donor liver transplantation using left lateral segment consists of end‐to‐end anastomosis between the donor left hepatic artery and the recipient right hepatic artery. In the present case, an intra‐operative hepatic artery thrombosis occurred because of extensive intima wall dissection of the recipient hepatic artery. The patient was a 6‐yr‐old boy with fulminant hepatic failure, who underwent living donor partial liver transplantation with left lateral segment from his father. The graft was irrigated by a left hepatic artery and an accessory left hepatic artery from gastric artery, both arteries with diameter of <2 mm. These arteries were anastomosed to the recipient right and left hepatic arteries, respectively. Before performing the bile duct reconstruction it was noted that these anastomoses were occluded by clots of blood. An extensive subintimal dissection of the recipient hepatic artery was the cause of this problem. The creation of a new anastomosis by using a more proximal part of this artery without subintimal dissection was judged impossible. Then, the right gastroepiploic artery was mobilized and an anastomosis was performed with the donor left hepatic artery in an end‐to‐end fashion. Arterial blood flow to the graft was established successfully and the patient's postoperative recovery was excellent. Fifteen days after the transplantation, an angiotomography demonstrated a good hepatic arterial blood flow. The patient is now alive and well, 4 months after the transplantation. In conclusion, the method of hepatic graft arterialization described here is an important option for patients who undergo living donor or split liver transplantation.
