describe how portal vein thrombosis cause ascites
Portal vein thrombosis occurs when a blood clot blocks or partially blocks the portal vein, which carries blood from the intestines to the liver. This blockage can lead to increased pressure in the portal vein, causing a backup of blood flow in the veins of the liver. This can result in increased pressure in the liver, leading to decreased blood flow in the liver and decreased production of proteins that help regulate fluid balance in the body.
As a result, fluid may accumulate in the abdomen, causing ascites. Ascites is the abnormal buildup of fluid in the abdominal cavity, which can lead to swelling, discomfort, and difficulty breathing. In cases of portal vein thrombosis, ascites can be a sign of advanced liver disease and can be a serious complication requiring medical attention.
