The Importance Of The Ligation The Inferior Thyroid Artery In Parathroid Function Agter Subtotal Thyroidectomy

The parathyroid gland located behind the thyroid gland in the neck produces parathyroid hormones which, along with vitamin D and calcitonin, are important for the regulation of the calcium level in the body. Hypoparathyroidism is the result of a decrease in production of parathyroid hormones. The result is a low level of calcium in the blood. The parathyroids are small glands. Because of their small size, their delicate blood supply, and their usual anatomical position adjacent to the thyroid gland, these structures are at risk of being accidentally removed, traumatized, or devascularized during thyroidectomy. The complication associated with thyroid surgery is the development of acute, transient or chronic parathyroid insufficiency resulting from the removal of the glands or the damage to their vascularisation. The lowest complication rate of chronic hypoparathyroidism is observed in patients subjected to subtotal resection. The ligation of the inferior thyroid artery was not an important causal factor for the occurrence of postoperative hypocalcemia after subtotal thyroidectomy.
