Which intervention is contraindicated in hepatic hydrothorax?

• A. Thoracentesis
• B. Chest tube drainage
• C. Diuretics
• D. TIPS

Answer: (B)

Hepatic hydrothorax occurs when ascitic fluid passes through small defects in the diaphragm into the pleural space, driven by portal hypertension. The aim of treatment is to reduce the source of fluid and portal pressure, not to continually drain the pleural space. Diuretics (to mobilize fluid) and therapies that lower portal pressure, like TIPS, address the underlying mechanism. Thoracentesis can provide temporary relief of symptoms, but repeatedly removing large volumes isn’t curative and carries risks of protein loss and electrolyte disturbance. Draining the pleural space with a chest tube is contraindicated because it creates a conduit that perpetuates drainage of ascitic fluid into the pleural cavity. This can lead to significant protein loss, hypovolemia, electrolyte imbalances, infection risk, and does not address the portal hypertension driving the hydrothorax. It may worsen the patient’s overall condition and fails to treat the root cause.
