Thoracentesis

Overview

Definition

A pleural effusion is a buildup of fluid in the space between the lungs and the chest wall. This space is called the pleural space. Thoracentesis is a procedure to remove fluid from this area.

There are 2 types of thoracentesis:

  • Therapeutic thoracentesis—to relieve the symptoms of fluid buildup
  • Diagnostic thoracentesis—to test for the cause of the fluid buildup

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Collapsed lung
  • Fluid building up again
  • Bleeding
  • Infection
  • Damage to the lung, liver, or spleen
