Value of parathyroid hormone assay for preoperative sonographically guided parathyroid aspirates for minimally invasive parathyroidectomy

Purpose. The key to successful parathyroid surgery is accurate preoperative tumor localization. This study investigates the use of ultrasound (US)-guided parathyroid fine needle aspiration (FNA) as a confirmatory diagnostic method in patients with hyperparathyroidism undergoing minimally invasive parathyroidectomy
