Which procedure removes pleural fluid for diagnostic or therapeutic purposes?

• A. Thoracentesis
• B. Pleural effusion drainage
• C. Thoracostomy
• D. Pericardiocentesis

Answer: (A)

Removing pleural fluid for diagnostic or relief purposes is done with thoracentesis. The pleural space sits between the lung and chest wall, and when fluid accumulates, a clinician can insert a needle or small catheter through the chest wall into this space to aspirate fluid. This sample is analyzed to uncover the cause of the effusion (cell counts, cytology for cancer, infection tests, protein and LDH to classify exudate versus transudate), and removing fluid can also lessen shortness of breath in large effusions. Thoracentesis is distinct from chest tube placement, which is used for ongoing drainage in emergencies or when continuous fluid or air removal is needed. Pericardiocentesis removes fluid from the pericardial sac around the heart, not from the pleural space. A vague term like pleural effusion drainage isn’t a precise, standard name for a single procedure, whereas thoracentesis specifically refers to the procedure used to remove pleural fluid for diagnostic or therapeutic purposes.
