Level of parathyroid hormone in the early postoperative period as a prognostic factor for persistent manifestations of clinical hypocalcemia

Objective — to determine the level of parathyroid hormone (PTH) in early postoperative period patients after thyroid gland surgery, which enables define risk persistent hypoparathyroidism with clinical manifestations hypocalcemia.
 Materials and methods. The study involved 303 who were operated Ukrainian Scientific Practical Center for Endocrine Surgery, Transplantation Organ Tissue due various pathologies January, 2020 through June, 2021. scope operation was thyroidectomy with/without lymph node dissection. PTH blood serum determined all morning surgery (16 22 hours later). Clinical signs hypocalcemia (PTH < 15 pg/ml) revealed 147 (48.5 %) subjects. Moving forward, such examined levels 3 months (first stage examinations) 6 (second examinations).
 Results. After months, normalization no defined 126 (85.7 %); 21 (14.3 had low (< hypocalcemia. use ROC‑analysis predict cut‑off threshold 2.8 pg/ ml. 136 (92.5 patients, whereas 11 (7.4 subjects demonstrated reduced Results prediction post‑surgery, 1.6 pg/ml.
 Conclusions. Postoperative > pg/ml established be a predictor levels. A can considered hypoparathyroidism, allows physician recognize possible long‑term specific treatment.
