Portal vein thrombosis
-
Portal vein thrombosis is blockage or narrowing of the portal vein (the blood vessel that brings blood to the liver from the intestines) by a blood clot.
Most people have no symptoms, but in some people, fluid accumulates in the abdomen, the spleen enlarges, and/or severe bleeding occurs in the esophagus.
Doppler ultrasonography can usually confirm the diagnosis.
The cause is treated if possible, related problems are treated, and drugs may be used to dissolve the clot or to prevent the clot from enlarging or recurring.(See also Overview of Blood Vessel Disorders of the Liver.)
Because the portal vein is narrowed or blocked, pressure in the portal vein increases. This increased pressure (called portal hypertension) causes the spleen to enlarge (splenomegaly). It also results in dilated, twisted (varicose) veins in the esophagus (called esophageal varices) and often in the stomach (called gastric varices). These veins can bleed profusely.
Fluid accumulation in the abdomen (called ascites) is not common. But it may develop when people also have liver congestion (backup of blood in the liver) or liver damage, such as severe scarring of the liver (cirrhosis), or when large amounts of fluids are given intravenously to treat massive bleeding from ruptured varicose veins in the esophagus or stomach. If portal vein thrombosis develops in people with cirrhosis, their condition deteriorates.
