Visceral angiography was performed in 7 patients with normal portal pressure and in 10 with portal hypertension. Circulation times, size of vessels and portal pressure were determined. At celiac angiography a direct correlation was found between time for maximum filling of portal vein and portal pressure, provided no vascular abnormalities existed. At superior mesenteric angiography such a correlation was not found; loss of flow by shunts in portal hypertension being one explanation. Portocaval shunts are common in the celiac system, but uncommon in the superior mesenteric system.
对7例门静脉压力正常的患者和10例门静脉高压患者进行了内脏血管造影。测定了循环时间、血管大小和门静脉压力。在腹腔动脉造影时，若不存在血管异常，门静脉最大充盈时间与门静脉压力之间存在直接相关性。在肠系膜上动脉造影时未发现这种相关性；门静脉高压时分流导致血流减少是一种解释。门静脉-腔静脉分流在腹腔动脉系统中常见，但在肠系膜上动脉系统中不常见。
