The most widespread technique for catheterization of the portal venous system is the percutaneous transhepatic with selective catheterization of the portal tributaries. The procedure is most often used for portography in patients with liver cirrhosis, but can also be used for pharmacoligic, metabolic and hemodynamic studies. By selective catheterization of the gastrooesophageal veins varices can be obliterated. Selective catheterization of the pancreatic veins with blood sampling for hormone assay may diagnose and localize endocrine pancreatic tumours.
门静脉系统插管最常用的技术是经皮经肝门静脉分支选择性插管。该操作最常用于肝硬化患者的门静脉造影，但也可用于药理学、代谢和血流动力学研究。通过对胃食管静脉进行选择性插管，可消除静脉曲张。对胰腺静脉进行选择性插管并采血进行激素测定，可能有助于诊断和定位胰腺内分泌肿瘤。
