Value of color doppler ultrasonography on portal vein lesions after liver transplantation

Objective To investigate the clinical value of color Doppler ultrasound on portal vein complications after liver transplantation. Methods Twenty-seven cases of portal vein disease in patients with liver transplantation were selected as portal vein disease group, including 19 cases of portal vein thrombosis, 5 cases of portal vein stenosis, 3 cases of portal vein trunk occlusion; 27 cases without complications after liver transplantation were selected as no portal vein disease group, 30 healthy volunteers were selected as control group. The hemodynamic differences among the 3 groups were observed. Results In the portal vein disease group, the liver artery diameter increased, the maximum flow velocity increased, the resistance index decreased(F=4.258, 15.88, 4.237, P 0.05). There was no obvious change in the hepatic venous flow(P>0.05), the fluctuation index increased(F=8.257, P<0.05). Conclusions Color Doppler ultrasound detection can dynamicly and directly show the abnomality of portal vein disease after liver transplantation, and important clinical value.
