Abstract

Thyroid cancer is the leading cancer in the endocrine system. Over the past few decades, the incidence of this pathology worldwide has increased at a higher rate than other cancers. The main method of treatment for thyroid cancer is surgical. Some of the complications that can result from surgical treatment are tracheomalacia and trachea damage. Tracheomalacia is a pathological softening of tracheal rings resulting from prolonged compression of the trachea resulting in degenerative changes in cartilages. As a result of the removal of the thyroid tumor, a defect of its wall may form. Damage of the trachea can occur when the thyroid isthmus is separated from it. In addition, when separating the thyroid gland from the trachea, performing central lymphodissection, the blood supply of the trachea may be disturbed, which is carried out according to the segmental type, characterized by a lack of the number of collaterals. There is presented a clinical case of successful treatment of a rare complication after thyroid surgery for papillary cancer in the form of trachea in a patient of 49 years. By analyzing the clinical example, taking into account the macroscopic picture of trachea defects, their location and dimensions, it is possible to assume segmental disorder of blood supply of the upper third of the trachea in the postoperative period with the development of ischemic changes and regions of necrosis of ring ligaments. In order to prevent such complications in thyroid operations, it is necessary to preserve the paratracheal vascular anastomotic network by carefully preparing the tracheal branches of the lower thyroid artery.
