title: CT-guided percutaneous drainage of lung abscesses: review of 40 cases.
abstract: OBJECTIVE
  To evaluate the safety and effectiveness of CT-guided percutaneous drainage of lung abscesses considering success rate versus complications.
  
  
  METHODS
  This retrospective study was carried out at Computed Tomography and Interventional Radiology Department of Sotiria Hospital, Athens, Greece, from 1/1/2007 to 1/1/2010. Forty patients with lung abscesses in which antibiotic therapy failed and were managed with CT-guided percutaneous drainage were included in the study. Catheter placement was carried out using Trocar technique in the majority of the cases.
  
  
  RESULTS
  Lung abscess completely resolved with no residual cavity in thirty three patients. Seven patients had residual cavity and surgery was performed. Thus, the success rate of radiological drainage of the lung abscesses (33/40) was 83%. Five (13%) patients developed pneumothorax. Three developed moderate pneumothorax and chest-tube needed to be inserted and two patients developed mild pneumothorax which was managed with aspiration. These patients were kept under observation and followed-up by chest X-rays. No other complications and no mortality occurred during the procedure for all the forty patients.
  
  
  CONCLUSIONS
  CT-guided percutaneous catheter drainage is a useful and safe procedure for the treatment of patients with lung abscesses who do not respond to medical therapy and should be considered a valuable alternative to open surgery.
