The imaging quality of the portal vein was obviously improved with prostaglandin E1 (PGE1) indirect portal vein digital subtraction angiography (DSA) in 23 cases. The time-density curve showed that the occurrence rate of opposite hepatic blood flow of splenic vein (SV) was the highest (17.4%). The total visualization rate of the left gastric vein (LGV) was 78.3%, and the visualization rate of the short gastric vein (SGV) was 36.4%. 38.9% of the LGV and all the SGV were visualized with indirect portal vein DSA through SA. Indirect portal vein angiography through superior mesenteric artery and that through splenic artery were of equal importance. In portal hypertension patients with hemorrhage of the digestive tract, when LGV and SGV could not be visualized in PGE1 indirect portal vein DSA, the possibility of non-varices vein bleeding should be considered. When opposite hepatic blood flow with obvious dilation appeared in LGV and SGV, devascularization of the pericardial blood vessels would be justifiable.
23例患者采用前列腺素E1（PGE1）间接门静脉数字减影血管造影（DSA）时门静脉成像质量明显提高。时间-密度曲线显示，脾静脉（SV）反向肝血流发生率最高（17.4%）。胃左静脉（LGV）总显影率为78.3%，胃短静脉（SGV）显影率为36.4%。38.9%的LGV和所有SGV通过经脾间接门静脉DSA显影。经肠系膜上动脉间接门静脉造影和经脾动脉间接门静脉造影具有同等重要性。在门静脉高压合并消化道出血的患者中，当PGE1间接门静脉DSA不能显示LGV和SGV时，应考虑非静脉曲张静脉出血的可能性。当LGV和SGV出现明显扩张的反向肝血流时，心包血管去血管化是合理的。
