Intrahepatic portal hypertension contributes to fluid accumulation in the abdominal cavity (ascites) by forcing more fluid across the liver capsule into the abdominal cavity than the body is capable of draining. Acute portal hypertension may cause mild to moderate enlargement of the spleen, but marked enlargement requires sustained portal hypertension over a long period of time. Protein-containing fluid (ascitic fluid) may leak from the surface of the liver and intestines and expand (distend) the abdominal cavity, a condition called ascites. Varicose veins in the esophagus (esophageal varices) and in the upper part of the stomach bleed easily and sometimes massively. Varicose veins in the rectum may also bleed, though this is much less common.
