Hepatic Hydrothorax (HH) occurs in 5-10% of cirrhotic patients and remains a significant clinical challenge. Despite medical therapy with diuretics and sodium restriction, many patients still experience intractable, debilitating dyspnea and respiratory compromise. Repeated thoracentesis, while often effective, may affect prohibitively transient symptom relief and exposes the patient to repeated procedures with inherent cumulative risk. Trans-jugular intrahepatic porto-systemic shunt (TIPS), while a valuable treatment for HH, is not always effective or able to be performed. Similarly, liver transplantation although potentially curative, is not available to many patients and may be significantly delayed. Many patients do not experience sufficient or timely relief with current conventional therapy. There exists the need for additional therapies, either as a bridge to transplantation or TIPS, or for palliation when transplantation is not expected.
