What is a common complication of portal hypertension associated with liver cirrhosis?

Portal hypertension is a significant complication arising from liver cirrhosis, characterized by an increase in blood pressure within the portal venous system. One of the hallmark manifestations of portal hypertension is the accumulation of fluid in the abdominal cavity, known as ascites. This occurs due to increased pressure in the portal veins, which leads to the transudation of fluid into the peritoneal space.

In patients with cirrhosis, the liver's ability to produce albumin is often compromised, contributing to decreased oncotic pressure. This decreased pressure, combined with increased hydrostatic pressure from portal hypertension, facilitates the movement of fluid out of the vascular system and into the abdominal cavity.

Ascites is not only a direct result of portal hypertension but also reflects the overall severity of liver disease. Management of ascites often includes dietary sodium restriction, diuretics, and in some cases, paracentesis or shunting procedures to relieve the pressure. Understanding ascites in the context of portal hypertension is critical for effectively managing patients with liver cirrhosis.
