TCD评价脑腔隙性梗死的临床意义

Clinical value of TCD in cerebral lacuna infarct

目的探讨经颅多普勒(TCD)检查在脑腔隙性梗死中的应用价值。方法对30例经CT、MRI证实为脑腔隙性梗死患者进行TCD检查,并对TCD的表现差异进行分析。结果30例脑腔隙性梗死患者大部分以头痛头昏、肢体麻木就诊,TCD表现为脑血管痉挛,脑供血不足的血流速度改变。结论TCD检查可以明确以不同临床症状就诊的脑腔隙性梗死患者的脑动脉血流动力学改变。

Objective To investigate the clinical value of transcranial Doppler （TCD） in cerebral lacuna infarct. Methods TCD examination was performed on 30 patients of cerebral lacuna infarct confirmed by CT and MRI. The differenices on TCD were analyzed. Results Most of 30 patients suffered from headache, dizzy and limbs anaesthesia. TCD showed the changes of blood flow velocity due to convulsion of cerebral vessels and shortage of blood supply. Conclusion TCD can detectet the changes of hemodynamics of patients with cerebral lacuna infarct suffered from different symptoms.
