Objective  To explore the accuracy and efficiency of indocyanine green fluorescence (ICGF) imaging in evaluating blood perfusion of parathyroid gland (PG) during total thyroidectomy. Methods  Seventy patients who underwent total thyroidectomy and bilateral central lymph node dissection for papillary thyroid carcinoma (PTC) from March 2021 to December 2021 were enrolled and randomly divided into experimental group (ICGF imaging, n=35) and control group (normal treatment, n=35). Blood perfusion of PGs was evaluated by ICGF imaging and naked eye in each group respectively. The perfusion of PGs, incidence of hypoparathyroidism, and number of autotransplanted PGs were analyzed between the two groups. Results  There was no difference between two groups in the incidence of transient hypoparathyroidism (P=0.339), and no one occurred permanent hypoparathyroidism. More PGs were autotransplanted in the experimental group compared to the control group (P<0.001). At least one PG with good perfusion in the experimental group predicted an extremely high rate of normal parathyroid hormone levels of the patients postoperatively than the control group (P=0.003). Conclusion  ICGF imaging can evaluate the blood perfusion of PGs accurately and guide their autotransplantation.
