Hepatic artery reconstruction with inferior mesenteric vein graft in pediatric living donor liver transplantation

Abstract

We report a transplant of the left lateral liver segments with two arteries for a pediatric recipient from a live donor. A six-month-old female patient was diagnosed with liver cirrhosis secondary to biliary atresia and scheduled for LDLT (father as donor). Left lateral hepatectomy was performed at the donor site. The dissection of the left HA, which divided immediately after its origin, showed two branches for segments II and III. The artery for segment III was anastomosed to the recipient HA. The artery for segment II was too short for direct anastomosis with the gastroduodenal artery. After an unsuccessful attempt to use of the recipient's saphenous vein, the recipient's IMV was used as an interposition graft. No post-operative complications were observed. The outcome of this case demonstrates that left lateral segments with two arteries can be successfully used if proper surgical techniques are applied. From this experience we can recommend the IMV as an alternative to the saphenous vein for an interposition graft.
