hepatic venous outflow obstruction

Hepatic venous outflow obstruction is a condition where blood cannot flow properly out of the liver through the veins. Normally, blood from the liver drains into the larger veins and then back to the heart. When this flow is blocked or restricted, it causes increased pressure in the liver, which can lead to liver swelling, pain, and sometimes fluid buildup in the abdomen (ascites). This can result from various causes such as blood clots, scarring, or external pressure on the veins. Proper diagnosis and treatment are important to prevent further liver damage and related complications.
