Co-axial needle biyopsi with computed tomography at torax mass's (performing, results and evaluation of the complications)

Summary:In this study in Dicle University Radiology Department fromSeptember 2004 to November 2006 performances, complications andresults of co-axial cutter needle biopsy procedure to thoracic masses wereevaluated. 61 needle biopsy were performed to 58 patients between theages 30-70.Pathology studies showed 19 (% 32.8) benign, 39 (% 67.2) malignlesions, and specific diagnoses were provided in 44 (% 75.9) patientswhich contained 9 (%47.4) malign and 35 (% 89.7) benign lesions.Diagnostic specificity was 87.5 percent.Complications of this procedure were determined as pneumothoraxin 9 (% 16.1), paranchymal hemoragie in 5 (% 15.6) and hemopthisia in2 (% 3.6) patients.Incidence of pneumothorax was determined significiantly higher atthe cases in which paranchymal distance passed through was over 2 cm.Masses, defined with irregular contures and lobulations wereresulted with statistically higher malignity rates in pathology studies.In conclusion, at the diagnosis of thoracic masses computedtomography guided needle biopsy with cutter co-axial system is a methodwith easy performance, high diagnostic accuracy rates and lowcomplication rates.
