Angiographic or scintigraphic localization of parathyroid adenomas is successful in only a small number of patients with hypercalcaemic hyperparathyroidism. This report is concerned with the preoperative localization of parathyroid adenomas by regional catheterization of the thyroid veins in patients with hypercalcaemic hyperparathyroidism (n = 7). PTH was determined radioimmunologically, using an antiserum specific for PTH1-84 and the carboxyl-terminal fragment of the hormone. Determination of regional differences in the plasma concentration of PTH permitted the preoperative localization of PTH secreting adenomas. The preoperative localization of parathyroid adenomas was confirmed in each instance by surgery. Thus, the regional determination of plasma PTH represents a tool to improve the preoperative localization of parathyroid adenomas in patients with hypercalcaemic hyperparathyroidism and, hence, to reduce the risk of an unsuccessful operation.
甲状旁腺腺瘤的血管造影或闪烁显像定位仅在少数高钙血症性甲状旁腺功能亢进患者中成功。本报告关注的是通过对高钙血症性甲状旁腺功能亢进患者(n = 7)的甲状腺静脉进行区域导管插入术来对甲状旁腺腺瘤进行术前定位。使用针对PTH1 - 84和该激素羧基末端片段的抗血清,通过放射免疫法测定甲状旁腺激素(PTH)。测定血浆PTH浓度的区域差异可实现分泌PTH腺瘤的术前定位。每次甲状旁腺腺瘤的术前定位均通过手术得到证实。因此,血浆PTH的区域测定是一种改善高钙血症性甲状旁腺功能亢进患者甲状旁腺腺瘤术前定位的工具,从而降低手术失败的风险。
