Pleural Effusion

Symptoms of a pleural effusion may include:

• Trouble breathing.
• Shortness of breath.
• Chest pain.
• Fever.
• A cough.

A minor pleural effusion may not cause any symptoms.

A pleural effusion is usually diagnosed with an X-ray and a physical exam. The doctor listens to the airflow in your lungs.

A pleural effusion can be treated by removing fluid from the space between the tissues around the lungs. This is done with a needle that’s put into the chest (thoracentesis). A small amount of the fluid may be sent to a lab to find out what is causing the buildup of fluid.

Removing the fluid may help to relieve symptoms, such as shortness of breath and chest pain. It can help the lungs to expand more fully.

If the pleural effusion doesn’t get better, a catheter may be placed in the chest. This is a flexible tube that allows fluid to drain from the lungs. The catheter stays in the chest until the doctor removes it. Some people may get a treatment that removes the fluid and then puts a medicine into the chest cavity. This helps to prevent too much fluid from building up again.

A minor pleural effusion often goes away on its own.

Doctors may need to treat the condition that is causing the pleural effusion. For example, you may get medicines to treat pneumonia or congestive heart failure. When the condition is treated, the effusion usually goes away.

For a pleural empyema, the pus needs to be drained. It may drain from a flexible tube placed in the chest. Or you may have surgery to drain it. You also will get antibiotics.
