Routine chest roentgenograms after thoracentesis are not always necessary. Individualizing their use and adhering to protocols can minimize risks like iatrogenic pneumothorax, especially when performed by trainees.
Area of Science:
- Pulmonology
- Thoracic Surgery
- Medical Procedures
Background:
- Thoracentesis is a common procedure for pleural effusion management.
- Iatrogenic pneumothorax is a potential complication of thoracentesis.
- Current guidelines on post-procedure imaging vary.
Purpose of the Study:
- To evaluate the necessity of routine chest roentgenograms following thoracentesis.
- To determine the incidence of iatrogenic pneumothorax after a protocolized procedure.
- To assess factors influencing pneumothorax development.
Main Methods:
- Prospective study of 104 thoracentesis procedures in 76 patients.
- Procedures followed a standardized protocol.
- Chest roentgenograms were obtained within 6 hours post-procedure.
- Physician questionnaires collected patient and effusion data.
Main Results:
- Two cases (2%) of pneumothorax occurred post-thoracentesis.
- Neither pneumothorax required pleural drainage.
- Pneumothoraces were observed in patients with parapneumonic effusions.
Conclusions:
- Routine post-thoracentesis chest roentgenograms may not be universally indicated and should be individualized.
- Protocol adherence and physician training can reduce pneumothorax risk.
- Further studies could refine indications for post-procedure imaging.

Pneumothorax-II
Clinical Manifestations:
Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
