Multi-slice spiral CT angiography before and after liver transplantation

Objective To assess the clinical value of multi-slice CT in the preoperative and postoperative of liver transplantation.Methods Seven patients (6 males, 1 female, mean age 45 years old) performed MSCT multi-phase scanning before and after liver transplantation, multislice CT angiography with volume rendering. CT findings were compared with operation.Results There were 7 hepatocirrhosis, among them 2 cases with serious liver atrophy and 4 with hepatocellular carcinoma, three-dimensional volume rendering combined with MIP and MPR depicted 100% hepatic arteries, hepatic vein, portal vein and main branches. CTA showed 1 case with variation of hepatic artery, 1 case with hepatic artery stenosis and 1 case with portal vein stenosis and 1 case with portal vein thrombosis. After transplantation there was 1 case with hepatic artery complication and haematoma. Conclution Multi-slice spiral CT angiography provided comprehensive parenchymal, vascular, and volumetric evaluation, and thus is a feasible diagnostic tool in pre- and postoperative liver transplantation.
