摘　　要：目的 了解北京万寿路地区2121名老年人群颈动脉、下肢动脉粥样硬化病变发病率情况。方法 选择北京市万寿路社区≥60岁的居民进行分层整群随机抽样,共2121例。应用彩色多普勒超声检查每位老年人颈动脉及下肢动脉,分别检测动脉内中膜厚度(IMT)、斑块形成、管腔狭窄情况,进行统计分析。结果 万寿路地区2121名老年居民颈动脉IMT增厚1375例(64.8%)、斑块形成1179例(55.6%),均高于下肢动脉1307例(61.6%)、1100例(51.9%),两者差异有统计学意义(χ2=4.69、5.92,P均<0.05)。颈动脉及下肢动脉均以多发斑块居多。1179名颈动脉斑块居民中,发生在动脉分叉处728名(61.7%),1100名下肢动脉斑块居民中,发生于股总动脉处942名(85.6%)。结论 应用超声检查可早期识别动脉粥样硬化范围和程度,明确血管狭窄部位和狭窄程度,对预测和预防心脑血管疾病的发生有实际临床意义。Objective To investigate the prevalence of carotid atherosclerosis(CAS)and lower extremity atherosclerosis among people of Wanshoulu community in Beijing.Methods A total of 2121 individuals were randomly selected.Each individual received Doppler ultrasonic examination for observation of the internal-media thickness(IMT)and structures of the carotid and lower extremity arteries.Results A total of 1375 cases had increased IMT of the carotid arteries(64.8%,2121) and 1179 cases had plaques in the carotid arteries(55.6%,2121);1307 cases had increased IMT of lower extremity arteries(61.6%,2121) and 1100 cases had plaques in lower extremity arteries(51.9%,2121).The incidences of IMT increasing and plaque formation in the carotid arteries were significantly higher than those in lower extremity arteries(χ2=4.69,5.92,P<0.05).However,most plaques were multiple in the two locations.Carotid plaques always happened where the artery bifurcates(61.7%,728/1179) and most of the plaques in lower extremity arterial(85.6%,942/1100)located at the common femoral artery.Conclusion Ultrasound can evaluate atherosclerosis at different locations,which have clinical significance to predict and prevent the occurrence of vascular complications in carotid and lower extremity.
