Transjugular intrahepatic portosystemic stent-shunt placement has shown great promise as a means of portal decompression in patients with severe portal hypertension. Passage of a needle from the hepatic venous system into the portal venous system during this procedure may be technically difficult; while it would be advantageous to precisely target the portal vein, most methods of localization are themselves technically difficult, risky, or time-consuming. The authors describe a method of localization of the portal vein that, when feasible, appears to be both safe and technically simple. This method involves percutaneous catheterization of a paraumbilical portosystemic collateral vein under sonographic guidance.
