Non-invasive evaluation on therapeutic effect of transjugular intrahepatic portosystemic shunt and percutaneous transhepatic varices embolization using acoustic structure quantification method
Objective:To explore the diagnostic value of acoustic structure quantification(ASQ)technique in noninvasive assessment of transjugular intrahepatic portosystemic stent(TIPS)and percutaneous transhepatic varices embolization(PTVE). Methods:Quantitative assessment of 30 normal subjects and 30 patients who underwent TIPS and PTVE for treatment of portal hypertension(PHTN)was held by ASQ. The portal vein pressure was measured while placing the TIPS and PTVE. ASQ parameters of the plural,mean,standard deviation,...
