Methods and materials
In our study,
we retrospectively evaluated 89 patients who underwent CT-guided FNAB of pulmonary nodules between April 2016 and March 2017.
All procedures were performed using a 22 G Chiba-type needle (length 9-15 cm) in a sterile ambient,
previous cutaneous disinfection and patient free breath.
A pathologist was present in the CT room who performed an extemporary evaluation after the first sampling using the Rapid On Site Evaluation (ROSE) method in order to check the adequacy of the FNAB smears,
cellular quantity and to do a preliminary diagnosis when it was possible.
If necessary a second sample was performed to have more cells used for cell-block analysis,
immunohistochemistry and Papanicolaou coloration. Using this technique a maximum of two punctures were necessary in all our cases.
CT-scans after the procedure were used to evaluate complications such as hemorrhage or Pneumothorax (PNX).
A thoracic drainage was implanted according with the thoracic surgeon in massive PNX cases.
Surgical biopsy and clinical follow-up were considered to evaluate the accuracy of the cytological diagnosis.
We also compared major complications (PNX and hemorrhage) with literature data.
