前循环缺血性卒中患者颈动脉彩超检查结果分析

目的 评估颈动脉彩超检查对前循环缺血性卒中患者的观测效果.方法 收集2012年3月至2014年12月期间来我院进行检查的颈动脉硬化患者120例,将65例急性前循环缺血性卒中患者作为观察组,55例非急性前循环缺血性卒中患者作为对照组.比较两组患者的颈动脉内膜中层厚度(IMT)的增厚情况、舒张末期流速(EDV)、阻力指数(RI)、收缩期最大峰值流速(PSV)、搏动指数(PI)、收缩早期加速时间(AT)和斑块检测情况,以及颈总及颈内动脉血流动力学参数.结果 观察组患者的IMT增厚情况明显高于对照组,差异具有统计学意义(P<0.05);观察组患者检测出颈动脉中、重度狭窄者22例,颈内动脉闭塞者1例,占35.4%,对照组患者检测出颈动脉中、重度狭窄者4例,占7.3%,两组比较差异具有统计学意义(P<0.05).观察组患者的颈内动脉EDV、PSV参数和颈内动脉AT参数均明显低于对照组,而颈内动脉RI、PI值则明显高于对照组,经统计学分析,差异均有统计学意义(P<0.05).观察组和对照组的血流壁切应力值分别为(12.98±3.052)和(10.61±4.072),TC值分别为(4.85±0.87) mmol/L和(5.34±0.74) mmol/L,差异均有统计学意义(P<0.0.5).结论 前循环缺血性卒中患者颈动脉彩超检查结果能够有效帮助医生确诊,为疾病的治疗赢得宝贵的时间.

Effect of carotid artery ultrasound in patients with anterior circulation ischemic stroke

Objective To evaluate the effect of carotid artery color Doppler ultrasound examination in patients with anterior circulation ischemic stroke. Methods One hundred and twenty patients with carotid atherosclerosis com-ing to our hospital for examination from March 2012 to December 2014 were enrolled in the study, including 65 patients of acute anterior circulation ischemic stroke (observation group) and 55 patients of non-acute anterior circulation isch-emic stroke (control group). The carotid intima-media thickness (IMT), end-diastolic velocity (EDV), resistance index (RI), peak systolic velocity (PSV), pulsation index (PI), acceleration time (AT), carotid plaque, hemodynamic parameters of common and internal carotid artery were compared between the two groups. Results IMT thickening in the observa-tion group was significantly higher than that of the control group (P<0.05). There were 22 cases of moderate to severe stenosis as well as 1 case of internal carotid artery occlusion in the observation group (accounting for 35.4%) and 4 cases of moderate to severe stenosis in the control group (accounting for 7.3%), with statistically significant difference be-tween the two groups (P<0.05). The EDV, PSV and AT of internal carotid artery in the observation group were signifi-cantly lower than those in the control group, and the internal carotid artery RI, PI were significantly higher than those in the control group (P<0.05). The wall shear stress values of blood flow, TC were (12.98 ± 3.052), (4.85 ± 0.87) mmol/L in the observation group and (10.61 ± 4.072), (5.34 ± 0.74) mmol/L in the control group, with statistically significant differ-ences between the two groups (P<0.05). Conclusion Carotid artery ultrasound helps diagnose anterior circulation isch-emic stroke and is of great value in the early treatment of the disease.
