title: Percutaneous computed tomography-guided aspiration and biopsy of intrathoracic lesions: Results of 265 procedures.
abstract: BACKGROUND
  Percutaneous computed tomography (CT)-guided needle aspiration and biopsy technique have developed over time as a method for obtaining tissue specimen. Although this is a minimally invasive procedure, complications do occasionally occur.
  
  
  OBJECTIVE
  The aim of the study was to evaluate the diagnostic yield and complications of 265 percutaneous CT-guided aspiration and biopsy procedures performed on various intrathoracic lesions.
  
  
  METHODS
  Data of percutaneous CT-guided aspiration and biopsy procedures of intrathoracic lesions performed over a 4 year period were retrospectively analyzed.
  
  
  METHODS
  Procedure details, radiological images, and pathological and microbiological reports were retrieved from radiology records and hospital information system. Technical success, diagnostic yield, and complication rates were calculated.
  
  
  RESULTS
  Total 265 procedures were performed for lung (n= 179), mediastinum (n= 73), and pleural lesions (n= 13). Diagnostic yield for lung, mediastinal, and pleural lesions was 80.7%, 74.2, and 75%, respectively, for core biopsy specimens. Major complication was noted in only one procedure (0.4%). Minor complications were noted in 13.6% procedures which could be managed conservatively.
  
  
  CONCLUSIONS
  Percutaneous CT-guided aspiration and biopsy procedures for intrathoracic lesions are reasonably safe with good diagnostic yield. Complications are infrequent and conservatively managed in most of the cases.
