Summary:
Hepatic hydrothorax is defined as the development of significant pleural effusion in a patient with cirrhosis without primary pulmonary or cardiac disease. This complication is seen in 4-10% of patients with cirrhosis. The pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm. We report two patients with posthepatitis cirrhosis presenting with a significant pleural effusion. The peritoneopleural communication was demonstrated by peritoneal scintigraphy. The role of the peritoneopleural pressure gradient is discussed.
