Percutaneous small bore catheter drainage in the management of lung abscesses.

For patients with pyogenic lung abscesses who do not respond to medical therapy, thoracotomy with pulmonary resection is the widely-accepted treatment of choice. Six patients with lung abscess who failed to respond to conservative medical management were treated by percutaneous catheter drainage using small catheters (10 Fr or smaller). Five patients showed prompt clinical improvement and the sixth improved after a modification in antibiotic therapy. All patients recovered with radiographic resolution of the abscess and were well at followup periods from two months to two years. In such patients, percutaneous drainage with small catheters provides an excellent clinical result with minimal risk and trauma.
