摘要
目的应用颈动脉超声筛查颈动脉狭窄,并探讨脑卒中高危人群颈动脉狭窄的发病率。方法选择356例患者,以60岁为界分为≤60岁组83例,>60岁组273例,其中高血压196例、冠心病145例、下肢动脉疾病97例、糖尿病134例,采用双功能彩色多普勒行颈动脉超声检查,并分析。结果与≤60岁组比较,>60岁组患者高血压、糖尿病、冠心病和下肢动脉疾病比例明显升高,差异有统计学意义(P<0.05)。颈动脉狭窄≥50%103例,占28.9%,其中颈动脉狭窄≥70%33例,占9.3%。年龄>60岁(OR=2.281,95%CI:1.191～5.673,P=0.013)、冠心病(OR=2.312,95%CI:1.162～4.593,P=0.018)、下肢动脉疾病(OR=2.135,95%CI:1.093～4.985,P=0.011)是颈动脉狭窄的影响因素。结论老年男性、冠心病、下肢动脉疾病人群是颈动脉重度狭窄的主要危险人群,也是颈动脉超声筛查的主要对象。
Objective To study the application of carotid artery ultrasonography in screening of ca- rotid artery stenosis（CAS） and the incidence of CAS in populations at a high risk of cerebral stroke. Methods Three hundred and fifty-six patients were divided into ≤60 years old group（n： 83） and 〉60 years old group（n=273）. Of these patients, 196,145,97 and 134 were diagnosed with hypertension, coronary heart disease（CHD）, lower extremity artery disease and diabestes mellitus（DM）, respectively. The patients received double functional color Doppler ultrasonogra- phy and analyzed. Results The incidence of hypertension,DM,CHD and lower extremity artery disease was significantly higher in 〉60 years old group than in≤60 years old group（P〈0.05）. Among the 356 patients,the CAS was ≥50%and ≥70%,respectively,in 103（28.9%）and 33 （9.3%）. Age 〉60 years（OR=2. 281,95%CI.1. 191-5. 673,P=0. 013）,CHD（OR=2. 312,95% CI;1. 162-4. 593,P=0. 018） and lower extremity artery disease（OR=2. 135,95%CI. 1. 093- 4. 985,P=0. 011） were the factors influencing CAS. Conclusion The elderly males with CHD and lower extremity artery disease are the main population at a high risk of severe CAS. Carotid artery ultrasonography is the principal method for screening of their CAS.
