超声对颈动脉斑块与脑卒中危险因素关系初探

A primary study of relationship between carotid plaque morphology and risk factors of ischemic stroke in high-frequency ultrasound

目的研究颅外颈动脉硬化性斑块与脑卒中危险因素的关系。方法运用高频超声对142例患者行颅外颈动脉检测。将颈动脉斑块分为七型两大类,比较不同斑块与高血压、糖尿病、冠心病、短暂性脑缺血发作TIA、高血脂、吸烟等危险因素的相关性。结果短暂性脑缺血发作TIA组不稳定斑块、特别透声斑的发生率明显增高,有统计学意义。其余危险因素无论在有斑块组与无斑块组之间,还是在不稳定斑块组与稳定斑块组之间,均无统计学差异。结论高频超声能够检测不稳定斑块,对预防缺血性脑卒中有指导意义。

Objective To analyze the relationship between carotid plaque morphology and risk factors of ischemic stroke. Methods A total of 142 patients were examined with high-frequency ultrasound. Carotid plaque was classified into seven types and two groups. Results The incidence of unstable plaque, especially sonolucent plaque in patients with transient ischemic attack was significantly increased than that of no TIA group. Other risk factors had no statistical significance between plaque group and no plaque group, or unstable plaque and stable plaque groups. Conclusion High-frequency color Doppler ultrasound can identify the unstable plaque,and prevent ischemic stroke to happen.
