Title: Assessment of portal vein embolism in the liver transplant candidates:comparison of ultrasound and spiral CT portography
Abstract: Objective To investigate the accuracy of ultrasound and spiral CT portography in detecting portal vein embolism in the liver transplant candidates.Methods One hundred and thirty-five patients before liver transplantation,underwent ultrasound and spiral CT portography.Among them,31 patients were subjected to contrast-enhanced ultrasonography.Results The accuracy of ultrasound and spiral CT portography in detecting portal vein embolism was 91.1%(123/135)and 86.7%(117/135),respectively.Co-examination improved the accuracy(96.5%)(P<0.05).The accuracy of contrast-enhanced ultrasound to differentiate between benign and malignant portal vein thrombosis was 100%,which was higher than that of ultrasound(58.6%),and spiral CT portography (73.9%)(P<0.05),respectively.Conclusions Both ultrasound and spiral CT portography had high accuracy in the diagnosis of portal vein embolism,and the accuracy of CO-examination was higher.contrast-enhanced ultrasonography could differentiate portal vein blood thrombosis from tumor thrombosis,and give more information.
