Abstract
Objective: Anatomic variations in the hepatic arteries were studied in donor livers that were used for orthotopic transplantation. Summary Background Data: Variations have occurred in 25% to 75% of cases. Donor livers represent an appropriate model for study because extrahepatic arterial anatomy must be defined precisely to ensure complete arterialization of the graft at time of transplantation. Methods: Records of 1000 patients who underwent liver harvesting for orthotopic transplantation between 1984 and 1993 were reviewed. Results: Arterial patterns in order of frequency included the normal Type 1 anatomy (n = 757), with the common hepatic artery arising from the celiac axis to form the gastroduodenal and proper hepatic arteries and the proper hepatic dividing distally into right and left branches; Type 3 (n = 106), with a replaced or accessory right hepatic artery originating from the superior mesenteric artery; Type 2 (n = 97), with a replaced or accessory left hepatic artery arising from the left gastric artery; Type 4 (n = 23), with both right and left hepatic arteries arising from the superior mesenteric and left gastric arteries, respectively; Type 5 (n = 15), with the entire common hepatic artery arising as a branch of the superior mesenteric; and Type 6 (n = 2), with the common hepatic artery originating directly from the aorta. Conclusions: These data are useful for the planning and conduct of surgical and radiological procedures of the upper abdomen, including laparoscopic operations of the biliary tract.
