Multislice computed tomography imaging of vascular complications in the recipients after living donor liver transplantation

Abstract

Objective: The purpose of this study is to describe the imaging characteristics of multi-slice computed tomography (MSCT) during the follow-up of liver transplant recipients in the first month.

Subject and method: Sixty-seven recipients after living donor liver transplantation at 108 Military Central Hospital were examined with triphasic hepatic computed tomography. Examinations were performed using a multi-slice computed tomography.

Result: In 67 patients (54 males & 13 females), the average age of patients was 55 years old, the youngest was 10 and the oldest was 75 years old. Indications for liver transplantation are mostly hepatocellular carcinoma (38.8%), acute liver failure (35.8%), and cirrhosis (23.9%). Arterial complications were found in 06 cases: hepatic artery thrombosis (02 cases), hepatic artery stenosis (03 cases), 01 case of synchronous pseudoaneurysm and hepatic artery thrombosis. We documented 12 cases of hepatic vein thrombosis and 01 case of inferior vena cava thrombosis.

Conclusion: MSCT is a non-invasive diagnostic method and very useful in detecting vascular complications in the recipients after LDLT, it provides synchronous evaluation of the hepatic vasculature, liver parenchyma. MSCTA is the best option to confirm suspicions of vascular complications on ultrasound. The detection of complications on MSCT greatly contributes to diagnosis and treatment.
