Recanalization of the ligamentum teres creates a portosystemic venous collateral. In portal hypertension, the fibrous ligamentum teres (the remnant of the fetal umbilical vein) can reopen to reestablish a connection between the portal system and systemic veins via the paraumbilical and abdominal wall veins. This provides an alternate route for portal blood to reach systemic circulation, often visualized as a collateral along the ligamentum teres toward the umbilicus. The other structures listed are not formed by this process: the hepatic artery is an arterial supply, the biliary canal carries bile, and hepatic veins drain the liver into the IVC—none arise from recanalization of the ligamentum teres.
