Superior mesenteric angiograms were obtained in a series of dogs before and again after the injection of a 1-ml bolus of prostaglandin E1 (0.1-1.0 mug/kg) through the angiographic catheter. The prostaglandin E1 produced, on the average, a 100% increase in the superior mesenteric arterial blood flow with only minimal changes in the heart rate, systemic arterial pressure, and portal venous pressure. Opacification of the portal venous system was consistently enhanced after the prostaglandin E1. The arterial phase was preserved by increasing the rate of contrast administration.
在一系列犬中，通过血管造影导管注射1毫升前列腺素E1（0.1 - 1.0微克/千克）推注前后分别进行肠系膜上血管造影。前列腺素E1平均使肠系膜上动脉血流量增加100%，而心率、体动脉压和门静脉压仅有微小变化。注射前列腺素E1后，门静脉系统的显影始终增强。通过增加造影剂注射速率来保留动脉期。
