Virtual Bronchoscopic Navigation Combined with Ultrathin Bronchoscopy. A Randomized Clinical Trial

American Journal of Respiratory and Critical Care Medicine, 2013
Abstract Rationale In bronchoscopy, an ultrathin bronchoscope can be advanced to more peripheral bronchi. Because virtual bronchoscopic navigation (VBN) is a method to guide a bronchoscope under direct observation using VB images, VBN may be particularly useful when combined with ultrathin ...

Ultrathin Bronchoscopy with and without Virtual Bronchoscopic Navigation: Influence of Segmentation on Diagnostic Yield

Respiration, 2018
<b><i>Background:</i></b> Bronchoscopy is a safe technique for diagnosing peripheral pulmonary lesions (PPLs), and virtual bronchoscopic navigation (VBN) helps guide the bronchoscope to PPLs. <b><i>Objectives:</i></b> We aimed to compare the diagnostic yield of VBN-guided and unguided ultrathin ...

A model of respiratory airway motion for real-time tracking of an ultrathin bronchoscope

SPIE Proceedings, 2007
Deformable registration of chest CT scans taken of a subject at various phases of respiration provide a direct measure of the spatially varying displacements that occur in the lung due to breathing. This respiratory motion was studied as part of the development of a CT-based guidance system for a new electromagnetically tracked ultrathin ...

[A barium marking method using an ultrathin bronchoscope with virtual bronchoscopic navigation].

Nihon Kokyuki Gakkai zasshi = the journal of the Japanese Respiratory Society, 2003
CT scanning of a 77-year-old woman showed a ground-glass opacity pattern shadow (9 x 7 mm) in the lower lobe of the right lung. To allow identification of the location of the lesion during thoracoscopic surgery, preoperative barium marking was performed using an ultrathin bronchoscope and virtual bronchoscopic navigation.

In VivoValidation of a Hybrid Tracking System for Navigation of an Ultrathin Bronchoscope Within Peripheral Airways

IEEE Transactions on Biomedical Engineering, 2010
Transbronchial biopsy of peripheral lung nodules is hindered by the inability to access lesions endoluminally due to the large diameter of conventional bronchoscopes. An ultrathin scanning fiber bronchoscope has recently been developed to advance image-guided biopsy several branching generations deeper into the peripheral airways. However, navigating a

Chronic necrotizing pulmonary aspergillosis successfully diagnosed, treated, and followed by ultrathin bronchoscope

Mycoses, 2007
SummaryWe present a case of chronic necrotising pulmonary aspergillosis (CNPA) successfully diagnosed, treated and followed by ultrathin bronchoscope. A 68‐year‐old man was admitted to the hospital because of a cough and low‐grade fever. A chest computerized tomography (CT) showed cavitary infiltrates in the superior segment of the left upper lobe ...

Effect of virtual bronchoscopic navigation in combination with ultrathin bronchoscopy for diagnosing peripheral pulmonary lesions

European Respiratory Journal, 2013
Background: We have previously shown the usefulness of virtual bronchoscopic navigation (VBN) for diagnosing peripheral pulmonary nodules using endobronchial ultrasound. Ultrathin bronchoscope can be inserted to more peripheral bronchi, and VBN can guide bronchoscope insertion.

Use of an Ultrathin vs Thin Bronchoscope for Peripheral Pulmonary Lesions: A Randomized Trial.

Chest, 2020
When evaluating peripheral pulmonary lesions, a 3.0-mm ultrathin bronchoscope (UTB) with a 1.7-mm working channel is advantageous regarding good access to the peripheral airway, whereas a 4.0-mm thin bronchoscope provides a larger 2.0-mm working channel, which allows the use of various instruments including a guide sheath (GS), larger forceps, and an ...

Bronchoscopic pursuit of the peripheral pulmonary lesion

Current Opinion in Pulmonary Medicine, 2016
Peripheral pulmonary lesions (PPL) are being diagnosed with increasing frequency, especially with the increased use of chest computed tomography (CT). Depending on the location and size, these lesions often present a diagnostic challenge in terms of the low yield of traditional bronchoscopic biopsy techniques or the risks of a percutaneous biopsy ...

Enhancing virtual bronchoscopic navigation route to small peripheral pulmonary lesions using lateral decubitus computed tomography with ultrathin bronchoscope: A single-center retrospective study

Respiratory Investigation
To evaluate the effectiveness of lateral-decubitus position computed tomography (LDCT) for bronchoscopic biopsies of peripheral pulmonary lesions (PPLs) in patients who underwent the procedure.In this retrospective single-center study, we included patients who underwent ultrathin bronchoscopy for PPLs after virtual bronchoscopic navigation (VBN) was ...
