title: [Hemodynamics monitoring of liver transplantation with color Doppler ultrasound].
abstract: By hemodynamic monitoring of liver transplantation with Color Doppler ultrasound, we observed the hemodynamic changes pre- and post-operatively and the patency of the anastomotic vessels, to detect or exclude the presence of complications, then assess the prognosis. We measured the hepatic blood flow after orthotopic liver transplantation in recent 6 cases, and observed the patency of anastomostic vessels and the hemodynamic improvement of the portal vein and hepatic arteries. The abnormal liquid and solid echoes were not found around the transplantated liver in all 6 cases. The echoes of hepatic parenchyma and tububes were normal. The direction and speed of blood flow were also normal. Five of anastomoses of portal vein in 6 cases were patent. The rest one was a little stenosed, and the speed of local blood flow was a little faster. There were 11 patent ones and 1 mildly stenosed in the 12 anastomoses of inferior venae cavae. The speed index(SI) and resistance index(RI) of hepatic arterial blood flow distal to the anastomoses were all normal. Liver transplantation is the redical therapying of portal hypertension, and the color Doppler ultrasound is the best non-invasived method for monitoring the hemodynamic changes of transplantated liver.
