Does Fluorescence With or Without Indocyanine Green Improve Parathyroid Identification and Preservation

ICG Administration: All enrolled patients with scheduled thyroidectomy or parathyroidectomy will receive a standard cervical incision that afford access to either side of neck. Following sufficient exposure of thyroid, 25 mg of indocyanine green (ICG), reconstituted in 10 ml of sterile water, will be administered intravenously. A dosage of 1 ml of this solution will be injected into a peripheral IV line, followed by a 5 ml flush of normal saline to ensure the propagation of the dye within the vascular compartment.

Fluorescent Imaging: Approximately 30 seconds post-administration, the parathyroid glands are expected to exhibit fluorescence under near-infrared imaging. The emitted fluorescence is anticipated to persist for approximately 20 minutes, allowing ample time for intraoperative evaluation of parathyroid viability and perfusion
