An animated primer on the physiological causes and effects of portal hypertension, which is defined by increased hydrostatic pressure in the hepatic portal vein. The hepatic portal system routes blood from the digestive tract through the liver to protect our bodies from any potentially dangerous substances we consume. When this system is blocked, pressure builds in the hepatic portal vein, which can lead to varices, hepatic encephalopathy, splenomegaly, and ascites. Treatments focus on managing these effects via medication and non-surgical procedures. If portal hypertension is caused by end-stage liver disease, e.g. cirrhosis, a liver transplant may be required.
