ABSTRACT

Objective Application of near-infrared fluorescent thoracoscope in visualizing thoracic sympathetic ganglions,to explore the effectiveness and safety of the technique.Methods Patients received near-infrared fluorescent thoracoscopic surgery was continuously in rolled from September 2015 to September 2016.The patient was infused indocyanine green 5 mg intravenous 24 hours before surgery.The thoracic sympathetic ganglions were observed under white and fluorescence model during surgery.The videos and photos were analyzed and the relationship between sympathetic ganglions and ribs was recorded.Results 31 patients was in rolled,including 12 males and 19 females.The average age was 47 years.The sympathetic ganglion of each patient was well visualized under fluorescence model.The signal to background ratio was 1.67.As we found that 48.8％ ganglions located in the upper edge of lower rib.Besides,26.9％ of T2 ganglions and 23.1％ of T3 ganglions located on the rib.Conclusion Near-infrared fluorescent thoracoscope was effiective and safety to visualize the thoracic sympathetic ganglions.The sympathectomy of palmar hyperhidrosis could be done by near-infrared fluorescent thoracoscope more precisely.
