Abstract:
CT-body divergence limits the accuracy of electromagnetic navigation bronchoscopy(ENB) in peripheral lung lesions diagnosis. Finding one effective and safe method to eliminating CT-body divergence may improve ENB accuracy. Thus, we developed a modified ENB which combining intraprocedural CT guided Navigation with Ventilatory strategy for Atelectasis to eliminate CT-body divergence. We called it inCTNVA-ENB. We present the case of an 80-year-old female with peripheral pulmonary nodule (without bronchial direct connection). She underwent inCTNVA-ENB, and the navigation probe accurately reached 6mm next to the target lesion without complications. The operation time was 42 minutes, and rapid on-site evaluation showed adenocarcinoma cells. CT data revealed the CT-body divergence caused by atelectasis was reduced.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
