Application of Bronchoscopic TransParenchymal Nodule Access in tuberculous bronchial occlusion.

Bronchoscopic TransParenchymal Nodule Access (BTPNA) technology is mainly used for sampling or ablative treatment of lung parenchymal lesions that cannot be reached by bronchoscopy and its appendages, generally for palliative treatment of some lung tumors. We used BTPNA to treat a 32-year-old young woman with pulmonary tuberculosis and successfully perforated her occluded left main bronchus. Her left atelectasis was recovered, and a silicone stent was inserted to preserve the shape of the left main bronchus.
