Signs and symptoms
Portal vein thrombosis can cause fever, symptoms of indigestion, and gradually worsening abdominal pain. However, it can also develop without causing symptoms, leading to portal hypertension before it is diagnosed. Other symptoms can develop based on the cause. For example, if portal vein thrombosis develops due to liver cirrhosis, bleeding or other signs of liver disease may be present. If portal vein thrombosis develops due to pylephlebitis, signs of infection such as fever, chills, night sweats may be present.
