Combining intraprocedural CT guided navigation with ventilatory strategy for atelectasis: A modified electromagnetic navigation bronchoscopy.

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 traprocedural guided avigation with entilatory strategy for telectasis 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.
