Role of Multi-slice CT and MRI in the Diagnosis of Complications after Liver Transplantation

Objective:To study the CT and MRI findings and the value of imaging in the diagnosis of complications following liver transplantation.Methods:The clinical materials of 78 patients underwent orthotopic liver transplantation (OLT) were reviewed,the CT and MRI appearances in patients with complications after liver transplantation proved by surgery,liver biopsy or cholangiography were analysed retrospectively.Results:Stenosis of main portal vein anastomosis (n=2),of hepatic arterial anastomosis (n=3),of inferior vena cava anastomosis (n=2) and inferior vena cava thrombosis (n=1) were assessed on CT and MRI.Stenosis of bile duct anastomosis (n=9) were revealed on MRI,stenosis of bile duct anastomosis (n=3) was depicted by CT.Complications included transplant rejection (n=3);other hepatic complications (n=4) including liver abscess (n=1),hepatocholangitis (n=2) and focal hepatic necrosis (n=1);complications of other organic systems (n=7) .Conclusion:Most of the complications after liver transplantation could be assessed on CT and MRI,which are effective in the diagnosis.
