Objective  To explore the feasibility of using high-definition thoracoscopy to identify sympathetic ganglia during endoscopic thoracic sympathicotomy for primary palmar hyperhidrosis. Methods The clinical data of patients with primary palmar hyperhidrosis who underwent thoracoscopic sympathectomy in Taikang Xianlin Drum Tower Hospital from June to July 2023 were retrospectively analyzed. At the same time, the operation video of patients with previous fluorescent thoracoscopic surgery was retrospectively analyzed.Results  Finally 100 patients were collected, including 54 females and 46 males, with an average age of 21.92±6.56 years. Five patients were intravenously administered with indocyanine green before operation. During operation, the rate of ganglion display was 92.5% (740/800), the rate of ganglion variation was 32.0% (237/740), and the improvement rate of hand sweat was 100.0% (100/100). In 5 patients with near-infrared fluorescence imaging, the coincidence rate between the ganglion identified under white light and the ganglion displayed by fluorescence was 100.0% (38/38). The display rate of ganglion under white light was 95.5% (107/112), and the display rate under near infrared fluorescence imaging was 96.4% (108/112), and the coincidence rate was 99.1% (107/108). Conclusion  With the wide clinical application of high-definition thoracoscopy, accurate thoracic sympathectomy has the feasibility of clinical application.
