64排螺旋CT血管造影对颈部动脉狭窄性病变的诊断价值

Diagnostic value of 64-slice spiral CT angiography in carotid artery stenosing lesion

目的探讨64排螺旋CT血管造影对颈部动脉狭窄性病变的诊断价值。方法对150例经彩色多普勒超声检查发现颈部动脉狭窄患者进行64排螺旋CT血管造影检查，分析颈部动脉狭窄发生部位、狭窄程度、斑块形态及成分。结果本组150例患者进行64排螺旋CT血管造影检查后，共分析颈部动脉900段，发现548处斑块。病变血管中轻度狭窄331段、中度狭窄160段、重度狭窄37段、闭塞20段。结论应用64排螺旋CT血管造影检查能够较准确评价颈部动脉狭窄性病变发生部位和狭窄程度，分析斑块形态及成分，并初步评估斑块的稳定性，能为临床选择适当的治疗方案提供影像学依据。

Objective To explore the diagnostic value of 64-slice spiral CT angiography （CTA） in neck ar- tery stenosing lesion. Methods 64-slice spiral CT angiographies were carried out in 150 patients with ca- rotid artery stenosis diagnosed by color Doppler ultrasound examinations, carotid artery stenosis sites, ste- nosing degrees, plaque morphology and components analyzed. Results After CTA 900 segments of carot- id artery were analyzed and 548 plaques discovered. Of lesion vessels, 331 segments were mild stenosis, 160 moderate, 37 severe, and 20 occlusion. Conclusion The application of 64-slice spiral CTA could eval- uate sites and stenosing degrees of carotid artery stenosis more accurately, analyze plaque morphology and components, evaluate plaques＇ stability initially, and provide imaging basis for selecting proper therapeutic schedule clinically.
