Abstract:
Objective To measure the changes of portal venous pressure before and after APS by percutanous portal vein catheterization and to quantitatively analyse the correlation between portal pressure and portal hypertension.Methods All the 18 central arterioportal shunts (APS) patients with hepatocellular carcinoma (HCC) were treated with embolization of APS and TACE, and the pressure of portal vein was measured by percutaneous portal vein catheterization pre- and post-embolization of APS. Color dopplar sonography and endoscopy were employed to investigate before and 2 weeks after embolization in all patients. Results The pressure of portal vein decreased significantly after embolization, and the decreased rate was 5.4%-33.3% with the mean rate 20.1%. After the embolization, the width of portal vein decreased and the blood flow velocity of portal vein increased significantly, P
