Surgical treatment of hyperparathyroidism with a pathologically changed parathyroid gland found in the mediastinum.

Abstract

The most common indication for surgical treatment of parathyroid gland pathology is primary hyperparathyroidism where extirpation of the pathologically changed parathyroid gland is the first-choice treatment. Embryonic development of the lower pair of parathyroid glands is quite complex and is closely related to the tissue of the thymus; for this reason it is not uncommon for a parathyroid adenoma to be located in the mediastinum or directly in the tissue of the thymus. The treatment of primary hyperparathyroidism is becoming a multidisciplinary issue in which radiodiagnostics and nuclear medicine methods play a significant role as they are needed to accurately localize the affected gland and to plan an adequate surgery. In case of intrathoracic localization of parathyroid adenoma, the therapy belongs in the hands of thoracic surgery. At our department, the endocrine surgery program, including parathyroid gland surgery, has a long tradition, and complicated patients are concentrated here, often patients with refractory hyperparathyroidism after a previous procedure. In the last 10 years, almost 2,300 procedures for parathyroid pathology have been performed at the IIIrd Department of Surgery of the 1st Faculty of Medicine, Charles University and University Hospital in Motol, of which some pathologies with mediastinal localization were managed using minimally invasive methods, i.e. videothoracoscopy or robotic-assisted surgery.
