Branch patch reconstruction in living donor liver transplantation: arterialization of grafts with replaced type arteries.
We developed a hepatic arterialization technique in living donor liver transplantation. The technique was indicated in patients with a left graft from donors with a right hepatic artery originated from superior mesenteric artery or a right graft from donors with a left hepatic artery from left gastric artery. The donor common hepatic and gastroduodenal arteries were split. On the recipient side, left and right hepatic arteries or branches of the right hepatic artery were split, received patch plasty, and anastomosed with the graft arteries under loupe observation. Livers from 25 donors were procured (16 right livers and 9 left livers) using this technique. There were no vascular complications in the donors. Three recipients died due to infectious disease with arterial patency. The remaining 22 recipients survived without hepatic arterial thrombosis. In limited situations, this technique can be adapted for living donor liver transplantation without increasing donor complications.
