SAVI SCOUT as a Novel Localization and Surgical Navigation System for More Accurate Localization and Resection of...

Background. Current techniques for localization and resection of lung nodules carry many intraoperative challenges for surgeons. This article proposes a new localization method for diagnosis and treatment of pulmonary nodules, which provides a navigational system for more accurate lung resection. Methods. We report the case of a 77-year-old female with a pulmonary nodule of the right lower lobe. A nonradioactive localization technology, known as SAVI SCOUT (Cianna Medical Inc, Aliso Viejo, CA), was placed by interventional radiology under computed tomography guidance preoperatively. Using the SCOUT Wire-Free Radar Localization System, the pulmonary nodule was robotically localized and resected. SCOUT removal was confirmed using the Trident Specimen Radiology System. The efficacy of this procedure was evaluated in terms of ease of use and procedure time by interventional radiology, surgical resection accuracy, diagnostic accuracy, simplicity, and ease to implement this technology in an existing hospital. Results. The SCOUT system allowed for the first reported case of successful SCOUT placement in lung tissue, targeted the pulmonary nodule intraoperatively, and facilitated accurate lung resection. Conclusions. The SCOUT system shows promising advancements in the ability to eliminate many challenges currently seen with lung nodule localization and resection.
