Identification of the Parathyroid Gland with Vasculature by Intraoperative Carbon Nanoparticles

Background: We aimed to investigate the ability of carbon nanoparticles identify parathyroid glands with vasculature during thyroid surgery. Material and methods: Totally 42 patients various diseases were selected for prospective research nanoparticle injection used in thyroidectomy. Another without receiving as control group. All cases underwent total or subtotal bilateral Before ligation superior inferior poles thyriod lobes, 0.1 mL a suspension was injected into two poles. Important tissues such recurrent laryngeal nerve, gland blood supply artery identified protected. Results: The not stained thus remained primary color all cases, while abnormal black. After 5 minutes, lobes original unchanged. Even parathyroids can be number autotransplantation one test group six At day after surgery, hypocalcemia became detectable four five Twenty-four instances hypoparathyroidism occurred at 1 surgery group, ten Conclusion: Intraoperatvie is an effective safe technique guiding plays important role identifying vasculatural glands, protecting physiologic function
