Venous outflow reconstruction is very important especially in right lobe living donor liver transplantation without middle hepatic vein. Various interposition (venous or synthetic) grafts have been recommended for the reconstruction of anterior sector tributaries. According to this study expanded polytetrafluoroethylene graft for venous outflow reconstruction is a feasible option.

Researchers aim to describe a surgical technique and analyze anterior sector venous reconstruction using expanded polytetrafluoroethylene graft. Retrospective analysis of prospectively collected data for 760 primary right lobe living donor liver transplantations were performed. Reconstruction of anterior sector: expanded polytetrafluoroethylene (group A, n = 705) and autologous vein (group B, n = 55).

--Pretransplant characteristics were comparable among both groups. Group A has significantly lower cold ischemia time and anhepatic time compared with group B.

--There was no difference in recovery pattern of liver functions, morbidity, and mortality between the 2 groups.

--One- and 6-month patency rates of interposition grafts were 97.6% and 84.4% (group A) and 96.4% and 78.1% (group B), respectively.

Conclusively, in centers with limited access to homologous or autologous vascular grafts, the use of expanded polytetrafluoroethylene graft for anterior sector venous outflow reconstruction in right lobe living donor liver transplantation is a viable option with excellent patency and patient outcomes.
