    Abstract:
    BACKGROUND: Congestion in the right paramedian sector of a right liver graft without a middle hepatic vein (MHV) may lead to graft dysfunction. To solve this problem, we have developed a technique for reconstructing the MHV tributaries of the right liver grafts by using the preserved recipient's native MHV trunk. METHODS: Between 2005 and 2007, among 34 right liver graft liver transplant patients with significant MHV tributaries (>5 mm in diameter), 21 patients underwent right liver graft living-donor liver transplantation: draining MHV tributaries with recipient's native MHV trunk. We evaluated the patency of the reconstructed MHV tributaries, graft regeneration, and graft survival. RESULTS: The 3-month patency rates of the reconstructed V8 and V5 were 92% and 76%, respectively. The 1-year survival rate and the regeneration index of the right paramedian sector 6 months after transplantation were higher in patients with reconstructed MHV tributaries than that for patients without reconstructed MHV tributaries. CONCLUSION: The use of the recipient's MHV trunk for the reconstruction of the MHV tributaries of the right liver grafts is considered to be a valuable and a feasible strategy in right liver graft living-donor liver transplantation.
