title: Preoperative localization of enlarged parathyroid glands: indication for and criteria in the evaluation of venous sampling.
abstract: The results of 45 non-selective and 26 selective preoperative localization examinations in patients with primary hyperparathyroidism are compared with the findings at operation. First operations are distinguished from re-operations. On the basis of personal observations and data from the literature, indications for preoperative localization examination are established. Criteria are formulated for the evaluation of the result of preoperative localization examination as correct, erroneous or inconclusive.
