Role Of Duplex Ultrasonography In Correlation With CT Angiography In Assessment Of Vascular Complications In Recipients Post Liver Transplantation

Abstract

Liver transplantation is a successful therapeutic option for patients with multiple irreversible acute and chronic liver diseases. Complications of liver transplantation can be divided into mechanical and non mechanical complications. During liver transplantation four donor structures must be reconnected sequentially from posterior to anterior to the recipient counter part, which are the inferior vena cava (IVC), the main portal vein (MPV), the hepatic artery, and the extrahepatic bile duct. Mechanical complications are encountered related to these Multiple complications can be observed afterliver transplantation. Although there is increasing survival of patientsafter OLT, the risk of complications after surgerypersists. Vascular complications are ones of themost common and life threatening complicationsafter OLT. As there are no specific clinicalfeatures or laboratory markers imaging playsthe main role in making correct diagnosis. Ultrasoundis the first line imaging modality forevaluating transplanted liver vasculature as it hasgood availability and in experienced hands may provide precise diagnosis. Three dimension multi-slice CT angiography with volume rendering can reveal common and potentially lethal vascular complications in patients who have undergone liver transplantation .it is a valuable technique for evaluating the
