Osmosis video - Portal hypertension

Portal hypertension is hypertension in the hepatic portal system, which is composed of the portal vein and its branches and tributaries. This can lead to serious complications, such as the development of enlarged veins in the esophagus and stomach, called varices, which can rupture and cause bleeding. It can also lead to ascites, an accumulation of fluid in the abdomen, and liver failure. Treatment involves medications to reduce pressure in the portal vein, such as beta-blockers like propranolol.
