What Are the Risks of Thoracentesis?
The risks of thoracentesis are usually minor and
will get better on their own, or they're easily treated. Your doctor may do a
chest x ray after the procedure to check for lung problems.
The risks of thoracentesis include:
- Pneumothorax.
This is a condition in which air collects in the pleural space (the area
between the lungs and chest wall). Sometimes air comes in through the needle,
or the needle makes a hole in a lung. Usually, a hole will seal itself. If
enough air gets into the pleural space, however, the lung can collapse. Your
doctor may need to put a tube in your chest to remove the air and let the lung
expand again.
- Pain, bleeding, bruising, or infection where the
needle or tube was inserted. In rare cases, bleeding may occur in or around the
lungs. Your doctor may need to put a tube in the chest to drain the blood. In
some cases, surgery may be needed.
- Liver or spleen injury. These complications are
very rare.
