Abstract:
Objective: To analyze the relationship of hepatic transit time and portal vein pressure in the patients with portal hypertension and esophagogastric varices, and to clarify its clinical significance. Methods: A total of 50 hospitalized patients underwent esophagogastric venous embolization due to portal hypertension and esophagogastric varices were selected as observation group, and 50 patients without history of liver disease and clinical manifestations of liver disease (hospitalized or out-patient) were selected as control group. All patients underwent liver contrast enhanced ultrasound. The free portal pressure (FPP) was measured by ultrasound guided portal vein puncture for operating pathways in the patients in observation group. The hepatic artery-hepatic vein transit time (HA-HVTT), the hepatic portal vein-hepatic vein transit time (PV-HVTT), the liver parenchyma- hepatic vein transit time (PA-HVTT) of the patients were compared between two groups. The correlations between HA-HVTT, PV-HVTT, PA-HVTT and FPP of the patients in observation group were analyzed. Results: The HA-HVTT, PV-HVTT and PA-HVTT of the patients in observation group were significantly shorter than those in control group 0=5.078, P<0. 01; t=\2. 163, P<0. 01; t=2. 649, PC0.01). The HA-HVTT, PV-HVTT and PA-HVTT had negative correlations with FPP in observation group ( r= 0.799, P
