高频彩色多普勒超声对原发性甲状旁腺功能亢进症的诊断及术前定位价值

目的:探讨彩色多普勒超声对原发性甲状旁腺功能亢进症的诊断及术前定位应用价值?方法:回顾性分析1998年8月~2009年4月本院手术的46例原发性甲状旁腺功能亢进患者,应用高频彩色多普勒超声技术检查甲状旁腺及超声为外科手术做术前定位的结果?结果:超声检出41例甲状旁腺肿块共计43个,检出率为89.1%(41/46),二维超声多表现为甲状旁腺区圆形或卵圆形低回声肿块,边界光滑整齐,多有包膜,常为单发,多位于甲状腺下动?静脉后方,彩色多普勒可见丰富的血流环绕肿块或深入肿块内部,血流多来源于甲状腺下动脉;频谱多普勒可探及动?静脉血流频谱?超声检出的甲状旁腺肿块均经手术证实,定位准确率为100%?结论:彩色多普勒超声是诊断原发性甲状旁腺功能亢进症的有效手段,并可作为临床术前定位的最理想方法?

The value of diagnosis and location before operation in primary hyperparathyroidism with high frequency color doppler ultrasound

Objective:To evaluate the value of color doppler sonography in the diagnosis and preoperative assistive positioning of primary hyerparathyroidism. Methods:We retrospectively analyzed the ultrasonographic results of 46 cases,who received surgical operations from 1998.8 to 2009.4. Results:Of all 46 patients,43 lesions were detected in 41 patients. The detection rate was 89.1% (41/46). Those lesions manifested as solitary,well demarcated,round or oval hypoechoic masses. The masses located posterior to the inferior thyroid vessels. In color doppler image,lesions were hypervascular. Arterial and venous flow parttern were detected by spectrum doppler. All the lesions dected by ultrasonography were testified by operation,and the accuracy of preoperation positioning was 100%. Conclusion:Color dopper ultrasonography is an effective method in the diagnosis of primary hyperparathyriodism and can be an optimal choice for the preoperative positioning.
