Applicability of prostaglandin E1 indirect portal vein angiography in patients with portal hypertension.
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.
