'''Portosystemic shunts (PSS)''' are anomalous vascular connections between the portal and systemic venous systems. These vessels shunt blood from the '''hepatic portal vein''' (deriving from the stomach, intestines, [[Pancreas - Anatomy & Physiology|pancreas]] and [[Spleen - Anatomy & Physiology|spleen]]) directly into '''systemic venous system''', bypassing the [[Liver - Anatomy & Physiology|liver]]. | '''Portosystemic shunts (PSS)''' are anomalous vascular connections between the portal and systemic venous systems.
