急性缺血性脑血管综合征患者颈椎动脉彩色多普勒超声探析

Study on color Doppler ultrasound of carotid arteries in patients with acute ischemic cerebrovascular syndrome

目的探析急性缺血性脑血管综合征患者颈椎动脉彩色多普勒超声临床诊断价值。方法将脑梗死患者、一过性脑缺血患者及无脑血管疾病者分别列为观察A组、观察B组和对照组,分别进行颈动脉多普勒超声检测,对三组颈部动脉的斑块情况,颈动脉脉动指数、血流阻力指数和血速情况,以及颈动脉狭窄情况分别予以比较分析。结果观察A组和观察B组患者中,颈动脉具有斑块者较之对照组明显要多,PI值均高于正常值1,较之对照组RI更高,血速更低,颈动脉整体狭窄率更高。另外,观察A组整体情况相对更差(P<0.05)。结论彩色多普勒超声在急性缺血性脑血管综合征患者诊断中具有重要的临床价值,值得推广应用。

Objective To study the diagnostic value of color Doppler ultrasound of carotid arteries for acute ischemic cerebrovascular syndrome （AICS）. Methods The patients with cerebral infarction, the patients with transient ischemic attack, and the patients without cerebrovascular disease were assigned to observation group A, observation group B, and control group, respectively. Color Doppler ultrasound of carotid arteries was performed for comparative analysis of carotid plaques, pulsatility index （PI）, resistance index （RI）, and blood flow velocity of the carotid arteries, and carotid stenosis. Results Observation groups A and B had significantly more patients with carotid plaques than the control group, and all the patients had a PI above 1. Furthermore, the observation groups had higher RI, lower blood flow velocity, and higher carotid stenosis rate compared with the control group. The condition was even worse in observation group A （P〈0.05）. Conclusion Color Doppler ultrasound has high diagnostic value for AICS and shows promise for clinical application.
