Thoracentesis

Pleural Tap

Risks

Thoracentesis is generally a safe procedure. A chest X-ray is usually done right after the procedure to make sure that no complications have occurred. Complications may include:

• A partial collapse of the lung (pneumothorax). This may occur if the needle used to remove the pleural fluid punctures the lung, allowing air to flow into the pleural space.
• Pulmonary edema, which may occur if a large amount of fluid is removed.
• Infection and bleeding.
• Damage to the liver or spleen, though this is rare.
