Abstract

Electromagnetic navigational (EMN) bronchoscopy is a novel approach to the diagnosis of pulmonary nodules and masses. The EMN allows the bronchoscopist to perform biopsies under virtual computed tomography guidance. This avoids the obstacles associated with real-time computed tomography guidance and the complications associated with percutaneous transthoracic needle aspiration. After diagnosis, if the lesion is found to be malignant, it is possible to implant coiled linear radiotherapy monitoring devices (RMDs), fiducial markers, into the lesion. This is carried out by using a 5-french angulated catheter. The catheter allows RMD placement in a radial pattern, which is ideal for focused radiotherapy. RMD implantation can allow fluoroscopic guidance for surgical resection as well. This technical vignette describes a therapeutic utility of EMN bronchoscopy in the implantation of RMDs into malignant lung nodules.
