    Author: Peng Z, Dai Z.
    Journal: Zhonghua Yi Xue Za Zhi; 1993 Jul; 73(7):403-5, 447. PubMed ID: 8293341.
    Abstract:
    The portal developing rates of 0%, 10%, 35% and 55% in portal hypertension were detected by prostaglandin E1(PGE1) indirect portal digital subtraction angiography (DSA). The rates of left gastric vein (LGV), short gastric vein (SGV), umbilical vein (UV) and spontaneous splenorenal Vein shunt collateral were 80%, 45%, 25% and 5% respectively and the confluent point of LGV was shown directly. Time--density curve depict showed that the hepatofugal blood flow rates of the main portal vein and splenic vein were 10% and 15% respectively. Color Doppler showed not only the imageology of the portal system, but the blood flow. The developing rates of LGV, SGV, UV and spontaneous splenorenal vein shunt collateral were 80%, 5%, 10% and 85% respectively. Following the improvement of portal developing grades, the main portal vein flow, splenic vein flow, and superior mesenteric vein flow were decreased. The results indicates the more poorly hepatopetal flow irrigation, the more intensive condition in high hemodynamics of the portal system.
