Portal vein arterialization for liver transplantation with extensive portomesenteric vein thrombosis: a case report.

We report herein a case of extensive thrombosis of portal venous system including mesenteric vein in a 70-year-old man who suffered from end-stage post-hepatitis C cirrhosis and who underwent orthotopic liver transplantation. There was no way to divert portal blood flow to the new liver because such an extensive thrombosis of portomesenteric venous system. There are some case reports of portocaval hemitransposition with some success but high mortality. We decided to arterialize the portal vein of the liver allograft with the recipient hepatic artery and the donor hepatic artery was anastomosed to the supraceliac aorta. He recovered slowly from the operation. At 1 year after the transplantation, he is doing well with perfect liver function tests. This case challenges our belief that portal blood flow is essential for the liver because of hepatotrophic factors.
