脑梗死患者颈动脉粥样硬化超声研究

目的　探讨脑梗死与颈动脉粥样硬化的关系。　方法　检测 5 8例脑梗死患者和 4 0例对照患者颈动脉内膜 -中膜厚度 ,斑块和附壁血栓情况 ,以及收缩期峰值流速和舒张期末流速。　结果　脑梗死组颈动脉内膜 -中膜厚度较对照组明显增厚 (P <0 .0 1) ,脑梗死组颈动脉收缩期的峰值流速、舒张末期流速均明显高于对照组 (P <0 .0 1) ,脑梗死组颈动脉粥样硬化斑块数量明显高于对照组 (P <0 .0 1)。　结论　颈动脉粥样硬化与脑梗死有相关性。超声早期检测颈动脉粥样硬化 ,可为卒中前的干预治疗提供重要依据。

Ultrasonographic study on carotid atheroscleosis in patients with cerebral infarction

Objective To study the relationship between carotid athrosclerosis(CAS) and cerebral infarction with ultrasonography. Methods The quantifiation of intima-medium thickness(IMT),identification of plaques, systolic peak velocity(SPV) and end diastolic velocity(EDV) of the bilateral carotid artery were detected by ultrasonography. Results The mean intima-medium thickness(IMT) in patients with cerebral infarction was significantly increased than that of the control group(P<0.01). In the cerebral infarction group,92 plaques(79.3%) were observed,while only 37 plaques(46.3%) were found out in the control group. The systlic peak velocity and end diastolic velocity were significantly increased in the bilateral carotid artery of patients with cerebral infarction than those of the control group(P<0.01). Conclusion CAS and cerebral infarction are closely related.CAS can be diagnosed in patients with cerebral infarction,which is important to forecast the onset of cerebral infarction.
