Objective: To study the clinical significance of doppler color flow imaging in monitoring the hemodynamic changes in portal system of patients with hepatic cirrhosis, and its influence on prognosis of the disease. Methods: Using doppler color flow imaging to measure the diameters of portal vein and splenic vein, blood stream velocity, and blood flow quantity of patients with hepatic cirrhosis that had and hadn’t ascitic fluid (ASC and no-ASC groups), and that had the complication of hemorrhage of upper digestive tract (HEM group). In the same time, hepatic function of the patients were detected, and a group of healthy people were checked as normal control (COL group). Results: The diameters and blood flow quantity of portal vein and splenic vein of the patients were larger than those of control group (P0.01). The blood stream velocity of portal vein of the patients was slower than that of control group (P0.01). The blood stream velocity in portal vein of the patients in HEM group was slower than those of patients in ASC and no-ASC groups (P0.05). The blood flow amounts in veins of patients in ASC and HEM groups were smaller than that of no-ASC group (P0.05), while the blood stream velocity in splenic vein of patients of HEM group was faster than those in ASC and no-ASC groups (P0.01). Conclusions: The increase of splenic vein blood flow quantity is an important cause resulting portal hypertension and hepatic function damage. The hepatic cirrhosis patients with faster splenic vein blood stream velocity could easily caught complication of superior digestive tract hemorrhage.
