Utility of using Indocyanine green to locate parathyroid adenoma and predict hypocalcemia

Abstract

Introduction: Secondary hypocalcemia due to hypoparathyroidism is a frequent complication of parathyroidectomy, which has certain difficulties in terms of intraoperative localization of the gland, since the surgeon uses his sight, touch and experience, to reach the task of the surgical act. Clinical case: 62-year-old woman, who started her current condition 8 months ago when she was diagnosed with osteoporosis, with hypercalcemia and significant elevation of parathyroid hormone. Cervical ultrasound and 99mTc-MIBI scintigraphy were requested, showing a nodular image compatible with parathyroid adenoma in the left lower thyroid lobe. The patient underwent left inferior parathyroidectomy with the use of indocyanine green. Conclusion: The identification of a parathyroid adenoma intraoperatively with the aid of fluorescence appears to be a reproducible, safe and easy way to use when treating this type of endocrine pathology.
