头晕、头痛患者彩色经颅多普勒(TCD)检测结果与应用价值分析

Dizziness,headachepatients with transcranial color doppler( TCD) detectionresults and The Application of value analysis

目的：探讨头晕、头痛患者彩色经颅多普勒（ TCD）检查结果与临床诊断中的应用价值。方法：对2009年1月∽2011年12月来我中心就诊主诉为头晕或头痛，且无明显神经系统定位体征的患者195例，进行彩色经颅多普勒（ TCD）血流动力学检测，包括双侧颈总动脉（CCA）、颈外动脉（ECA）、颈内动脉（ICA）、大脑中动脉（MCA）、大脑前动脉（ACA）、大脑后动脉（PCA）、椎动脉（ VA）、基底动脉（ BA）的血流速度方向、搏动指数、频谱形态、异常声频等检测。结果：195例头晕、头痛患者血流速度增快81例（41．54﹪），血流速度减慢63例（32．31﹪），两侧同名动脉血流速度不对称20例（10．26﹪）；头痛以动脉血流速度增高和两侧同名动脉血流速度不对称为主、头晕以动脉血流速度减慢为主；青年组以血流增高为主，中老年组以血流减慢为主。结论：彩色经颅多普勒（ TCD）对影像学检查难以获得有诊断价值的头晕头痛提供可靠的诊断依据。

Objective：To study the patients with dizziness , headache transcranial color doppler （ TCD） examination results and the ap-plication of the clinical diagnosis value .Methods：From January 2009 to December 2011 to our center complained of dizziness or head-ache, no obvious nervous system positioning and signs of 195 cases of patients, taking transcranial color doppler （TCD） hemodynamic de-tection, including the bilateral common carotid artery （CCA）, external carotid artery （ECA）, internal carotid artery （ICA） and middle cerebral artery （MCA）, before the cerebral artery （ACA）, posterior cerebral artery （PCA）, vertebral artery （VA） and basilar artery （ BA） direction of blood flow velocity and pulse index , spectrum shape , abnormal audio detection , etc.Results：195 patients with dizzi-ness, headache, 81（41.54﹪） cases of the rapid blood flow, slow blood flow velocity in 63 cases （32.31﹪）, on both sides of the same name artery blood flow velocity asymmetry 20 cases （10.26﹪）;Headache to higher blood flow velocity and on both sides of the same name artery blood flow velocity asymmetry was given priority to , dizziness was given priority to with artery blood flow velocity slowed;Youth was given priority to with blood flow increased , in the elderly group was given priority to with slow blood flow .Conclusion：Transcra-nial color doppler （ TCD） could have diagnostic value on imaging examination is difficult to get dizzy headache to provide reliable diagnos -tic basis.
