Introduction: Variations on the anatomy of the hepatic artery are common, with incidence of 20-50%. In liver transplantation, back-table reconstruction is often necessary for an easier and prompt arterial anastomosis and so, the use of arterial patches has been related to lower the incidence of complications. However, when a right hepatic artery variation from the superior mesenteric artery is present, the reconstruction occasionally produces twisting and flow problems.
Methods: Is described a surgical alternative for right hepatic artery variation reconstruction using a Carrel-patch from the superior mesenteric artery. The patch is anastomosed with the splenic artery stump to allow vertical orientation and improve blood flow.
Results: Among 120 liver transplants, four consecutive cases of right hepatic artery variation were reconstructed using this technique. All of them showed good flow and patency in postoperative period.
Conclusion: The proposed technique proved to be an interesting alternative for the reconstruction of right hepatic artery variation in liver transplantation.
