Usefulness of ICG Angiography-Guided Thyroidectomy for Preserving Parathyroid Function

To assess the appearance of postoperative hypoparathyroidism, a systematic determination of PTH and corrected calcium values will be carried out the morning after the intervention. It will be considered that there is hypoparathyroidism when the patient presents symptoms of hypocalcaemia, when he has required the administration of calcium and/or vitamin D prior to this determination or when he presents corrected calcium values \< 1.8 mmol/L.
