Thoracic empyema: management with image-guided catheter drainage

Area of Science:

• Thoracic Surgery
• Interventional Radiology
• Pulmonology

Background:

• Thoracic empyema, a serious pleural space infection, often requires drainage.
• Conventional surgical chest tube placement may fail in some cases.
• Minimally invasive image-guided catheter drainage offers an alternative treatment modality.

Purpose of the Study:

• To evaluate the efficacy and safety of image-guided catheter drainage for thoracic empyema.
• To determine the success rate of image-guided catheter drainage as a primary treatment.
• To identify factors associated with treatment failure and complications.

Main Methods:

• Retrospective analysis of 43 patients with thoracic empyema treated with image-guided catheter drainage.
• Drainage procedures utilized ultrasound, computed tomography, or fluoroscopy guidance, individually or in combination.
• Assessment of treatment success, failure, and complications, including need for subsequent thoracotomy.

Main Results:

• Image-guided catheter drainage was successful in 31 of 43 patients (72.1%) as the primary treatment.
• Three patients (7%) required thoracotomy due to persistent pleural peel despite initial drainage.
• Procedure failure occurred in eight patients (18.6%) due to tube clogging, pneumothorax, or pleural peel progression.

Conclusions:

• Image-guided catheter drainage is a successful primary treatment for the majority of thoracic empyema cases.
• The procedure is associated with a low rate of major complications.
• Successful management requires understanding empyema pathogenesis, drainage principles, and image guidance techniques.
