Percutaneous computed tomography-guided aspiration and biopsy of intrathoracic lesions: Results of 265 procedures.

Abstract

Context: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.Aims: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.Settings and Design:Data of percutaneous CT-guided aspiration and biopsy procedures of intrathoracic lesions performed over a 4 year period were retrospectively analyzed.Subjects and 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.
