目的探讨偏头痛患者脑血管血流动力学变化。方法采用脑血管血流动力学分析仪对63例偏头痛患者进行脑血管血流动力学检测。结果偏头痛患者脑血流速度、流量明显减少,外周阻力增大,脑血管自身调节及血管壁弹性差,顺应性差。结论偏头痛患者脑血管处于痉挛状态,支持传统血管学说。 Objective To investigate the changes of cerebrovascular hemodynamics in patients with migraine. Methods Cerebral blood flow hemodynamics was measured in 63 migraineurs using the cerebral vascular hemodynamics analyzer. Results In patients with migraine, cerebral blood flow velocity and flow rate were significantly decreased, peripheral resistance increased, cerebrovascular self-regulation and vascular wall elasticity were poor, and the compliance was poor. Conclusions Migraine patients have cerebral vasospasm and support traditional vascular theory.
