| ［摘要］ 目的 通过70例颈动脉粥样硬化彩色多普勒超声诊断的回顾性分析，探讨其病因病理学改变规律。方法 病人分为糖尿病组11例，高血压组24例，脑梗塞组6例，颈性眩晕或椎基底动脉供血不足组18例，冠心病组5例和其他组6例。病变分为类脂质沉积、软斑、硬斑和复合斑。结果 颈动脉粥样硬化斑块形成和类脂质沉积共32例，疾病集中在60岁以上人群，其中男性20例（62.5%），女性12例（37.5%）。糖尿病组平均年龄67.7岁，颈动脉均有不同类型的粥样硬化斑块；高血压组平均年龄64.25岁，粥样硬化斑块的发生率为37.5%；脑梗塞组的平均年龄为68.2岁，有颈动脉粥样硬化斑块的病人占66.6%；颈性眩晕或椎基底动脉供血不足(VBI)组的平均年龄为62.3岁，粥样硬化斑块的发生率为22.2%；冠心病组平均年龄68.2岁，合并颈动脉粥样硬化斑块的病人达80%；各病例组年龄无明显差异。结论 糖尿病合并颈动脉粥样硬化斑块的发生率最高，依次是冠心病、脑梗塞、高血压和椎基底动脉供血不足。低血流剪切力和高牵张应力是动脉粥样硬化的主要危险因素。血管内皮功能障碍，也是动脉粥样硬化的重要因素。 |

| Abstract: |
| ［Abstract］ Objective To analyse the colore doppler supersonic diagnosis of seventy patients with carotid atherosclerosis disease and to explore the pathological changes regularity.Methods The patients were divided into diabetes mellitus group (n=11), hypertension group(n=24), cerebral infarction group (n=6), cervical vertigo or vertebrobasilar insufficiency group(VBI)(n=18), coronary heart disease group (n=5), other group(n=6). The lessions were lipid storage, the soft, hard and compound plaques.Results There are 32 case of patients with lesions of carotid atherosclerosis plaque and lipid deposition, 20 case of male（62.5%）, 12case of female（37.5%）. The average age of diabetes mellitus group was 67.7years. The average ageof hypertension group was 64.25years. The average age of cerebral infarction group was 68.2years. The average age of cervical vertigo or VBI group was 62.3years. The average age of coronary heart disease group was 68.2years. The prevalence of carotid artery plaque in hypertension and cerebral infarction group were 37.5% and 66.6% respectively. The prevalence of carotid artery plaque in cervical vertigo or VBI and coronary heart disease group were 22.2% and 80% respectively.There was no significant difference between the different age groups.Conclusion The diabetic patients with carotid atherosclerosis have the highest rates, followed by coronary heart disease, cerebral infarction, hypertension and vertebrobasilar insufficiency. Low-flow shear stress and high tretch stress is of atherosclerosis major risk.Vascular endothelial dysfunction is also an important factor. |
