title: [New intraoperative diagnostic methods in parathyroid surgery: intraoperative measurement of parathyroid hormone].
abstract: In thirty-seven patients undergoing parathyroidectomy from November 1999 to July 2000 with diagnosis of primary hyperparathyroidism the intraoperative intact parathyroid hormone level were studied. Preoperative samples of blood were taken from a peripheral vein before the beginning the operation. The second sample was taken 5 minutes after removal of parathyroid adenoma. The plasma intact parathyroid hormone concentration was measured by quick IRMA method. The preoperative high PTH levels reduced after excision of adenoma to the mean 18%. 33 patients had normal PTH levels after 5 minutes of removing. The total measuring time of quick PTH assay was about 30 minutes. The QPTH assay was a quantitative adjunct for the surgeon to ensure a successful parathyroidectomy. When the intraoperative QPTH level is not reduced to 50%, then the exploration should be continued and the probability of reoperation is decreased. They propose the application of the routine intraoperative measurement of QPTH level in all parathyroidectomy.
