Contrast-enhanced ultrasound in evaluation of intrahepatic hemodynamic changes after operation in patients with portal hypertension

Objective To explore the value of CEUS in evaluation of intrahepatic hemodynamic changes after operation in patients with portal hypertension.Methods Totally 17 patients with portal hypertension underwent CEUS before and after the operation.The CEUS related parameters were recorded,i.e.hepatic artery arrival time(HAAT),portal vein arrival time(PVAT)and hepatic vein arrival time(HVAT),and then the hepatic artery to hepatic vein transit time(HAVTT)and portal vein to hepatic vein transit time(PV-HVTT)were calculated.The differences of CEUS parameters before and after operation were compared statistically.Results HAVTT and PV-HVTT lengthened significantly after the operation(both P0.05).There is no significant difference of HAAT,PVAT and HVAT before and after the operation(all P0.05).Conclusion CEUS related parameters,such as HAVTT and PV-HVTT can be used to assess the intrahepatic hemodynamic changes in patients with portal hypertension after operation,and which provide a new non-invasive method to assess the short-time effects.
