Use of a branch patch with the cystic artery in living related liver transplantation.

Technical aspects in living-related liver transplantation are still under debate: the main pitfall is the arterial reconstruction due to the small diameter and the discrepancy between stumps, with a subsequent increased risk of arterial thrombosis. The gold standard is the microsurgical technique, that reports the lowest risk of thrombosis, but it is a time consuming procedure requiring a long training. Our method of choice reconstructing hepatic artery in right lobe is the use of the cystic artery as a branch patch with the recipient hepatic artery by loop magnification, saving time and with a low incidence of hepatic artery thrombosis

Living donor liver transplantation with left liver graft.

Small-for-size syndrome in LDLT is associated with graft exposure to excessive portal perfusion. Prevention of graft overperfusion in LDLT can be achieved through intraoperative modulation of portal graft inflow. We report a successful LDLT utilising the left lobe with a GV/SLV of only 20%. A 43 year-old patient underwent to LDLT at our institution. During the anhepatic phase a porto-systemic shunt utilizing an interposition vein graft anastomosed between the right portal branch and the right hepatic vein was performed. After graft reperfusion splenectomy was also performed. Portal vein pressure, portal vein flow and hepatic artery flow were recorded. A decrease of portal vein pressure and flow was achieved, and the shunt was left in place. The recipient post-operative course was characterized by good graft function. Small-for-size syndrome by graft overperfusion can be successfully prevented by utilizing inflow modulation of the transplanted graft. This strategy can permit the use of left lobe in adult-to-adult living donor liver transplantation
