紧张型头痛患者椎-基底动脉经颅多普勒超声检查的临床意义

THE CLINICAL SIGNIFICANCE OF TRANSCRANIAL DOPPLER EXAMINATION OF VER-TEBRAL-BASILAR ARTERIES IN PATIENTS WITH TENSION-TYPE HEADACHE

摘要:

目的:观察紧张型头痛(TTH)患者椎-基底动脉血流动力学改变,并探讨其临床意义。方法:TTH患者106例,其中伴有颅周肌障碍TTH(TTH-PM)42例和不伴有颅周肌障碍TTH(TTH-NOPM)64例;对照组48例,为无头痛症状的健康体检者。采用经颅多普勒(TCD)脑血流分析技术测定两侧椎动脉(VA)及基底动脉(BA)平均血流速度(Vm)。结果:TTH患者,尤其是TTH-PM患者椎-基底动脉Vm显著增快,且以右侧椎动脉更为明显。结论:TTH患者有椎-基底动脉血流动力学异常,以TTH-PM者更显著。

Abstract:

Objective: To investigate the changes in hemodynamics of vertebral-basilar arteries in patients with tension-type headache(TTH) . Methods; 106 patients with TTH,42 patients with a pericranial muscle disorder (TTH-PM) ,64 patients without involvement of the pericranial muscle (TTH-NOPM) and 48 normal healthy subjects without headache were studied. Mean velocity (Vm) in vertebral arteries(VA) and basilar arteries(BA) were measured using transcranial doppler(TCD). Results: The Vm of vertebral-basilar arteries in patients with TTH , especially TTH-PM were significantly increased, and the changes in Vm of right VA was more significant. Conclusion; These results support the hypothesis that TTH patients, especially TTH-PM patients, had hemodynanic disorders in vertebral-basilar arteries.
