Clinical significance examining the portal system hemodynamics of po rtal hypertension in patients with cirrhosis by color Doppler ultrasound / 中华超声影像学杂志

ABSTRACT

Objective　To examinate the portal system hemo dynamics of portal hypertension in patients with cirrhosis and analysis the rela tionship between the changes of the portal system hemodynamics and the Child-Pu gh grade.Methods　The portal system hemodynamics of portal hypertension we re examined in 100 patients with cirrhosis and 24 normal subjects used colo r Doppler ultrasound and 100 cirrhosis patients were graded by the Child-Pugh g rade.Results　There were significant changes in the portal system hemo dynamics of portal hypertension between cirrhosis and 24 normal subjects,the di ame ter of the portal vein(Dpv),the splenic vein(Dsv) and the superior mesenteric vein(Dsmv), the speed of the portal vein(Vpv),the spleni c vein(Vsv) and the superior mesenteric vein(Vsmv) ,the flow of the portal vein(Qpv),the splenic vein(Qsv) and the superior mesenteric v ein(Qsmv) were significantly increased (P<0.01),respectively.The Dpv of Child grade C patients were wider than the those of Child grade A a nd B patients(P<0.05), the Vpv of Child grade C patients had mo re decrease than the those of Child grade A and B patients(P<0.05), but Qpv was were no significant difference between Child grade A,B and C gro ups patients(P>0.05). Conclusions　Examination of the portal system hemodynamics of por tal hypertension in patients with cirrhosis can be used to evaluate the degree o f liver function and the portal hypertension in cirrhosis patients.
