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.
采用前列腺素E1（PGE1）间接门静脉数字减影血管造影（DSA）检测门静脉高压时门静脉显影率分别为0%、10%、35%和55%。胃左静脉（LGV）、胃短静脉（SGV）、脐静脉（UV）及自发性脾肾静脉分流侧支的显影率分别为80%、45%、25%和5%，并直接显示了LGV的汇合点。时间-密度曲线描绘显示门静脉主干和脾静脉的离肝血流率分别为10%和15%。彩色多普勒不仅显示了门静脉系统的影像学表现，还显示了血流情况。LGV、SGV、UV及自发性脾肾静脉分流侧支的显影率分别为80%、5%、10%和85%。随着门静脉显影等级的提高，门静脉主干血流、脾静脉血流及肠系膜上静脉血流均减少。结果表明向肝血流灌注越差，门静脉系统高血流动力学状态越严重。
