title: [Preoperative ultrasonic diagnosis and localization of enlarged parathyroid glands in suspected hyperparathyroidism].
abstract: Since August 1978, the neck of 68 patients with the clinical diagnosis of hyperparathyroidism was examined by ultrasound. The accuracy of the method increased from 61% during the first period of investigation to 82% using a newly-developed ultrasound scanner. These results are comparable with those obtained by invasive methods like angiography or selective venous blood sampling for the assay of parathyroid hormone. Positive preoperative localization of enlarged parathyroid glands confirmed the diagnosis of HPT. Cases involving acute HPT preoperative localization of enlarged parathyroid glands requires prompt surgical management. Preoperative localization of an adenoma allows direct removal of the enlarged gland and exploration of the others within the immediate section from microscopic examination under surgery.
