Predicting hypoparathyroidism after thyroidectomy: the value of indocyanine green fluorescence angiography

The location of PTG regarding the thyroid lobe significantly affects the preservation of their vascularization and thus their function after total thyroidectomy. The ICG fluorescence-based scores proposed in this study are a helpful tool to predict postoperative hypoparathyroidism, especially the mean fluorescence score, that does not depend on the number of recognized PTG. The mean fluorescence score may take part of the management of patients after thyroidectomy by guiding the need to use calcium supplementation and time of hospital discharge.
