OBJECTIVE: To evaluate the outcome and safety of ultrasound-guided percutaneous catheter drainage of exudative pleural effusion.

MATERIAL AND METHOD: The present study was a retrospective analysis of 412 pleural effusions from 373 patients that underwent ultrasound-guided small-bore catheter drainage in exudative pleural effusions between 2004 and 2009.

RESULTS: The two most common causes for drainage were parapneumonic effusion or empyema (52.2%) and malignant effusion (30.3%), while the remains were trauma, iatrogenic, and others. Overall clinical success rate was 76.5%. The success rate was lower among malignant pleural effusion (p = 0.003). Causes of effusion were the only independent predictors related to success. Only five (1.2%) patients developed complication during the procedure. Seventy-five of 412 effusions (15.8%) developed complication during the period of drainage; the majority were drain blockage (9%) and accidental dislodgment (4.1%).

CONCLUSION: Ultrasound-guided small-bore catheter drainage was a safe and efficient procedure for exudative pleural effusions.
