Percutaneous transthoracic needle biopsy of the lung : review of 612 lesions

摘要: Purpose The results and complications of 651 pulmonary fine-needle aspiration biopsies (FNABs) were reviewed. number needle passes size correlated to pneumothorax chest tube placement rates. Materials Methods FNAB the lung was performed on occasions in 612 patients with 18- 22-gauge Franseen needles. Diagnostic rates calculated. used evaluated for their association subsequent placement. Results accuracy 94% sensitivity malignancy 95%. Positive negative predictive values 99.5% 90%, respectively. Pneumothorax occurred 26.9% 9.2% requiring Increasing numbers larger sizes did not increase or Conclusions has excellent diagnostic remains procedure choice diagnosing lesions. This large study contradicts perceptions that decrease thinner needles fewer passes.
