The safety and feasibility of intraoperative near-infrared fluorescence imaging with indocyanine green in thoracoscopic sympathectomy for primary palmar hyperhidrosis.

• Significant findings of the study. NIR fluorescence imaging with ICG for identifying sympathetic ganglions is relatively safe and feasible. • What this study adds. This technology may take the place of the rib-oriented method as standard practice for the precise localization of sympathetic ganglions, and may improve the effect of sympathectomies.
