The umbilical vein in adults is patent but collapsed. There is a membranous valve at its entrance into the left portal vein. Cannulation of the portal vein via the umbilical vein permits direct access to the portal system for portography and hepatography. This procedure was performed under local or general anesthesia in 30 patients and was successful in 22. It is useful in the investigation of patients with portal hypertension, and suspected intrahepatic tumours or abscesses. It gives excellent contrast visualization of the liver and definition of lesions as small as 1.0 cm. This technique is superior to both hepatic scanning and splenoportography.
成人的脐静脉是开放的，但呈塌陷状态。在其进入左门静脉处有一个膜性瓣膜。经脐静脉对门静脉进行插管可直接进入门静脉系统以进行门静脉造影和肝脏造影。该操作在30例患者中于局部或全身麻醉下进行，22例成功。它对门静脉高压、疑似肝内肿瘤或脓肿患者的检查很有用。它能使肝脏获得极佳的造影显影，并能清晰显示小至1.0厘米的病变。该技术优于肝脏扫描和脾门静脉造影。
