A two-step strategy for enlargement of left arterial branch in a living related liver graft with dual arterial supply.
The use of small caliber arteries is probably responsible for the higher hepatic artery thrombosis rate initially reported after living related liver transplantation. We described a two-step strategy generating flow-induced enlargement of a small diameter artery in case of left graft dual arterial supply. The smaller arterial branch was ligated during a laparoscopic first-step procedure inducing a 30% enlargement of the remaining branch. The second-step donor hepatectomy was performed 1 week later using a larger artery for successful vascular anastomosis. The flow-induced enlargement of donor hepatic artery may help to reduce hepatic artery thrombosis risk after pediatric living related liver transplantation.
