Abstract: | INTRODUCTION: The number of available cadaveric donor organs has reached a plateau. One current solution has been to increase number of living related liver transplantations. MATERIAL AND METHODS: Since October 1999 in the Department of General, Transplant and Liver Surgery, Medical University of Warsaw, 40 living related liver transplantation have been carried out. RESULTS: In 31 (77.5%) cases, a normal arterial supply was observed: the common hepatic artery arose from a celiac trunk. In two cases (5.0%), there was a partial arterial blood supply by the right accessory hepatic artery originating from the superior mesenteric artery. In two cases (5.0%), a right hepatic artery arose completely from the superior mesenteric artery (replaced artery). In one case (2.5%), a common hepatic artery originated from the superior mesenteric artery. In two cases (5.0%), an accessory left segmental artery originated from the left gastric artery. In two cases (5.0%), the function of an absent left hepatic artery was assumed by a replaced left hepatic artery originating from the left gastric artery. In two (5.0%) cases, there were two separate ducts draining the right hemiliver. There were two (5.0%) cases of an accessory duct draining segment IV, originating within the confluence of the right and left hepatic ducts. In one (2.5%) case, the common hepatic duct showed a trifurcation. CONCLUSION: During harvesting from a living donor knowledge of anatomical variants must be used to optomize the liver graft. |
