目的研究与分析症状性颈动脉 狭窄应用64排螺旋CT检查临床价值。方法 将本院所收治的76例脑血管患者按照疾 病类型分组为对照组与观察组，各38例。 对照组为非缺血性脑血管疾病患者；观察 组为缺血性脑血管疾病患者；2组患者均 采用64排螺旋CT检查，并对2组患者双侧 颈动脉斑块类型、狭窄程度进行评价与分 析。结果 经研究发现，观察组患者发生 颈动脉狭窄率为78.95%(30/38)明显高于 对照组36.84%(14/38)(P<0.05)；观察组 各段血管主要以软斑为主，然对照组主要 以硬斑为主。结论 临床采用64排螺旋CT 用于临床诊断可有效判断患者动脉内斑数 量及性质，同时还可有效评估患者血管闭 塞及狭窄情况。因此临床应用64排螺旋CT 诊断症状性颈动脉狭窄具有极其重要的诊 断价值，从而为临床治疗方案选择提供重 要参考。

Objective Research and analysis the 64-slice spiral CT scan clinical value of symptomatic carotid stenosis. Methods The institutes will be admitted 76 cases of patients with cerebrovascular disease types grouped according to the control group and the observation group, 38 cases each. Patients with non-ischemic control group were cerebrovascular disease; observation group for patients were ischemic cerebrovascular disease; group 2 patients were treated with 64-slice spiral CT, and for two groups of patients with bilateral carotid artery plaque type, degree of stenosis evaluation and Analysis. Results The study found that patients with carotid artery stenosis observation group was 78.95% (30/38) significantly higher than 36.84% (14/38) (P<0.05); observation group segments vessels mainly in the soft spot based, However, in the control group mainly hard plaque based. Conclusion Patients with clinical use of 64-slice spiral CT vascular occlusion and stenosis can be effectively used in clinical diagnosis to determine the number and nature of plaque inside the arteries of patients, but also effectively assessed. Therefore, clinical application of 64-slice spiral CT in diagnosis of symptomatic carotid stenosis is extremely important diagnostic value, thus providing an important reference for clinical treatment options.
