无先兆型偏头痛患者颅外血管经颅多普勒的检测分析

Analysis of TCD examination of extracranial blood vessels in migraine patients without aura

目的探讨经颅多普勒（TCD）对无先兆型偏头痛患者头痛间歇期顿外血管的血液动力学变化。方法应用经颅多普勒（TCD）对96例无先兆型偏头痛患者的576根颅外血管进行TCD检测，并与29名正常人进行对照。结果在受检的576根颅外血管中，有283根血管峰血流速度异常升高，异常率为49．13％。颅外血管的异常高速血流主要表现为颈总动脉和颈外动脉，较正常人显著升高（P均＜0.01）。结论在偏头痛病人TCD检测中，不仅要考虑颅内血管的血流变化，更要注意观察顿外血管的血液动力学的改变。

The extracranial blood vessels of 96 migraine patients without aura duringheadache intermittence were examined by means of transcranial Doppler (TCD). Results Of 576 examined vessels, the peak flow velocity of 283 vessels increased and the abnormal rate was 49. l3%. Theabnormal high flow velocity in extracranial blood vessels was mainly involved in common carotid artery(CCA) and external carotid artery (ECA). Conclusion Besides considering blood flow change of intracranial vessels, we should more closely observe the hemodynamics alteration of extracranial bloodvessels in TCD examination of migraine patients.
