        ObjectiveTo share the experience of arterial plasty and reconstruction of variant arteries in living donor liver transplantation.MethodsFrom September 2006 to May 2010,73 living donor liver grafts(64 cases using the right lobe,9 cases using left lobe)were used in patients with end-stage liver disease.The hepatic arteries were evaluated preoperatively with computed tomography and magnetic resonance angiography.Back-table arterial plasty was performed under a microscope or a loupe according to arterial variation.We described technical points based on anatomic variations.There were 13(17.8%)liver grafts with anatomic hepatic arterial variations and all of these cases were subjected to back-table reconstruction with interrupted 8-0 or 9-0 nonabsorbable nylon monofilament sutures according to the diameter of artery.ResultsIn 3 cases,the associate right hepatic arteries that were arisen from superior esenteric arteris(SMA)were reconstructed to cystic arteries.In 2 cases with the associate right hepatic arteries arisen from the abdominal trunk,the right hepatic arteries and associate right hepatic arteries of donors were anastomosed with right hepatic arteries and left hepatic aryeries in recipients respectively.In 2 donors,hepatic arteries had branches,which were reconstructed.All of the arterial plasty were conducted on a back table.No arterial thrombosis was found during a postoperative follow-up period of 6 months.ConclusionLive donor liver transplantation using the right lobe with hepatic artery variation can be performed safely,but there is a potential operative risk of severe complication after transplantation.To minimize operative difficulties and complications,back-table reconstruction should be applied and proper treatment is given according to individual situations to ensure a safe and satisfactory outcome.11 refs,3 figs.
