Parathyroidectomy is the leading treatment for drug-refractory secondary and tertiary hyperparathyroidism in patients with chronic kidney disease. Difficulties in performing this surgery are mainly associated with the anatomical features of the parathyroid glands, in particular with the variability of their number and topographic anatomy. Ectopic parathyroid glands are one of the most common causes of persistence or recurrence of secondary hyperparathyroidism after surgery. One of the common variants of ectopia is the localization of the parathyroid gland in the anterior-superior mediastinum. The article discusses the features of surgical treatment of secondary hyperparathyroidism in patients with end-stage chronic kidney disease with this ectopia. A new method of treating hyperparathyroidism in patients with an atypical location of the parathyroid gland in the anterior-superior mediastinum is presented. This method is characterized by low invasiveness of access, ease of implementation without using special equipment and instruments. The proposed method was used in the treatment of a patient with secondary hyperparathyroidism due to chronic renal failure as a result of chronic glomerulonephritis. The duration of hemodialysis at the time of the surgery was more than 17 years. In the presented clinical case, ectopia of one of the pathologically altered parathyroid glands in the anterior-superior mediastinum was found at the preoperative stage. As a method of surgical treatment, we carried out total parathyroidectomy with autotransplantation of a fragment of parathyroid tissue into the brachioradialis muscle. Thanks to this method, it was possible to remove the atypically located parathyroid gland from the cervicotomy access and to discharge the patient within the standard terms for a given volume of surgery.
