Abstract

Introduction

Liver grafts can at times have two hepatic arterial stumps. This can result in a dilemma whether to reconstruct single or both the arteries. Hepatic artery (HA) thrombosis is the most dreaded complication in pediatric living donor liver transplantation (LDLT) as it can result in biliary complications and subsequent graft loss. We herein report the feasibility of reconstructing single hepatic artery in pediatric living donor liver transplantation having two arterial stumps in the liver graft.

Materials and methods

From 2008 to 2010, 87 pediatric patients undergoing LDLT were divided into three groups. Group 1 (n = 20): two HA stumps with two HA reconstruction, Group 2 (n = 22): two HA stumps with one HA reconstruction and Group 3 (n = 45): one HA stump with one HA reconstruction. The decision regarding the reconstruction of single or multiple HAs was made depending on the pre-operative radiological and intraoperative assessments.

Results

The incidence of HA thrombosis (p = 0.126) and biliary complications (p = 0.617), was similar in the three groups.

Conclusion

Single HA reconstruction does not increase the risk of biliary strictures in pediatric LDLT recipients having dual hepatic arterial stumps in the liver graft.
