A case report of uniportal video-assisted thoracic surgery left lower lobe wedge resection: guided by negative fluorography based on pre-block of watershed pulmonary arteries

Background: Accurate intraoperative localization of the nodules was key point sub-lobectomy resection. Percutaneous computed tomography (CT)-guided hook-wire most widely used method to locate pulmonary nodules, however, it associated with high rates pneumothorax and parenchymal hemorrhage. In recent years, surgeons were continuously seeking innovative approaches cover limitations CT-guided hook-wire. this article, we introduced an approach that based on topographic anatomy segments.
