【摘要】：目的探讨经颅多普勒超声检查(tcd)对脑动脉供血不足的临床诊断价值。脑动脉供血不足在中老年人群中多发,主要为反复性头晕和头痛,因患者个体差异,某些患者伴随视力模糊、四肢麻木等临床症状。在临床上较难诊断。方法选取2011年1月-2016年2月在本院诊断为脑动脉供血不足的患者72例为观察组,选取同时期80例健康体检正常者为对照组,分别检测大脑前、基底、椎、大脑中等动脉,检测频谱形态、血流速度和血流方向。结果经TCD检查,P均0.05;差异有统计学意义(P均0.05);结论经颅多普勒超声的诊断方法,对颅内椎基底动脉和颅外椎动脉进行全面检测,能提高准确率。
[Abstract]:Objective to investigate the clinical diagnostic value of transcranial Doppler ultrasonography (TCD) in the diagnosis of cerebral artery insufficiency, which is mainly recurrent dizziness and headache in the middle-aged and elderly population. Due to individual differences, some patients with blurred vision. Methods 72 cases of cerebral artery insufficiency diagnosed in our hospital from January 2011 to February 2016 were selected as observation group. In the same period, 80 normal subjects were selected as control group. The anterior, basal, vertebrae and middle cerebral arteries were detected, and the frequency spectrum, blood flow velocity and blood flow direction were measured. Results the results were examined by TCD. P both 0.05; The difference was statistically significant (P < 0.05). Conclusion the diagnostic method of transcranial Doppler ultrasound can improve the accuracy of detecting intracranial vertebrobasilar artery and extracranial vertebral artery.

【正文快照】： 脑动脉供血不足在临床上较为常见,但其病因不十分明确,且诊断困难。近年来,我们对我院5年间收治的72例患者进行经颅多普勒超声检查,并对结果进行分析,以明确病因诊断。TCD用2MHz的低发射频率与脉冲多普勒技术结合,通过颅骨特定的声窗,获得颅底主要动脉生理及病理的血流动力学
