Abstract
Portal vein thrombosis is a relatively common finding during liver transplantation. The management of portal vein thrombosis during liver transplantation is technically demanding and ensures adequate portal flow to the liver graft. Eversion thromboendovenectomy and bypass using a patent splanchnic vein and cavoportal hemitransposition are the most often used procedures to treat portal vein thrombosis. There have been anecdotal reports of portal vein arterialization. We report a case of portal vein arterialization during orthotopic liver transplantation for decompensated cirrhosis. When thromboendovenectomy failed to restore sufficient portal flow and completion of arterial anastomosis between the recipient hepatic artery and the donor celiac trunk, a calibrated end-to-side anastomosis between the donor splenic artery and the donor portal vein was performed. With a 6-year follow-up, there are no symptoms related to portal hypertension, liver function is normal. However, an aneurismal dilatation of the portal branches has progressively developed. Calibrated portal vein arterialization is a possible option for portal vein thrombosis in liver transplantation, allowing long-term patient and graft survival.
