Huge extrahepatic portal vein aneurysm as a late complication of liver transplantation

A 60-year-old male underwent orthotopic liver trans- plantation because of hepatitis C virus related cirrhosis. After 12 d,the patient underwent re-transplantation due to primary graft non function.One year later the patient developed a thrombosis of the main portal vein needing a surgical revision.After 11 years the patient was operated on because of a clinical picture of intestinal occlusion.As an incidental finding,a large aneurysm of the main portal vein was diagnosed.The incidence of intra-and extrahepatic Portal vein aneurysms(PVAs) is not clear.To the best of our knowledge,only one case of intrahepatic PVA in a liver transplant has been reported in the literature.In addition,we have found no documented cases of extrahepatic PVAs in liver transplanted patients.
