Preliminary exploration of the application of indocyanine green combined with near-infrared autofluorescence in the identification of parathyroid lesions
OBJECTIVE To explore the application value of indocyanine green combined with near-infrared autofluorescence imaging technique in identifying pathological parathyroid glands during surgery for primary hyperparathyroidism (PHPT). METHODS Data from 40 patients with PHPT treated in Beijing Tongren Hospital,Capital Medical University were collected,including 10 patients in the indocyanine green treated group and 30 patients in the non-treated group. All patients underwent surgical treatment to remove the affected parathyroid glands. Near-infrared autofluorescence imaging was used for image acquisition,and ImageJ software was used for fluorescence intensity analysis. RESULTS The fluorescence intensity of the pathological parathyroid glands in the indocyanine green-treated group was significantly higher than that in the non-treated group(142.7±23.7 vs. 94.5±31.4,t=-4.434,P=0.000);the fluorescence ratio of pathological parathyroid glands/thyroid glands was significantly higher than that in the non-treated group(1.6±0.3 vs. 1.2±0.4,t=-3.162,P=0.004). There was no correlation between the fluorescence intensity of parathyroid glands in the non-treated group and preoperative blood calcium(r=0.029,P=0.088) and preoperative PTH level(r=-0.142,P=0.455),and there was also no correlation between the fluorescence intensity of parathyroid glands in the treated group and preoperative blood calcium(r=0.206,P=0.568) and preoperative PTH level(r=0.160,P=0.658). The detection rate of near-infrared light in the non-treated group was 53.3％(16/30),while that in the treated group was 100％(10/10). The average detection time for the non-treated group was (71.0±16.9)minutes,while that for the treated group was (52.7±11.1)minutes,with a significant difference between the two groups(t=3.187,P=0.003). CONCLUSION The combination of indocyanine green and near-infrared autofluorescence imaging technique is helpful for identifying the diseased parathyroid glands during the surgical treatment of PHPT.
