[Pulmonary Nodule Localization by Pleural Marking Using Virtual Thoracoscopic Imaging].

Percutaneous or transbronchial markings are performed to localize pulmonary nodules preoperatively. We present a novel intraoperative procedure that utilizes virtual thoracoscopic imaging-assisted pleural marking. In this procedure, a virtual thoracoscopic image is created preoperatively, and the coordinates of the pleural point above the tumor are determined. The pleural marker is intraoperatively placed on the coordinates, and dye is transferred to the visceral pleura with two lung ventilations. We present the specific procedures and countermeasures for cases when nodules are not palpable. Additionally, we present a comparison between the various methods of preoperative marking and this method.
