| 目的 探讨中老年人群无名动脉分叉部粥样硬化病变的患病率及超声筛查的意义。 方法 选择在本院接受体检的受检者1619名,根据年龄分为40~49岁组、50~59岁组、60~69岁组和≥70岁组。超声观测各年龄组无名动脉分叉部内膜中层增厚和粥样硬化斑患病率,并与颈动脉各部位及锁骨下动脉起始部病变进行对比。 结果 40~49岁组、50~59岁组、60~69岁组及≥70岁组超声检测无名动脉分叉部内膜中层增厚及粥样硬化患病率分别为10.38%(22/212)、24.63%(50/203)、27.88%(126/452)、53.85%(343/637);单独病变检出率分别为90.91%(20/22)、66.00%(33/50)、32.54%(41/126)、11.37%(39/343)。无名动脉分叉部内膜中层增厚及粥样硬化在40~49岁组及50~59岁组的患病率明显高于颈动脉的各个部位及右锁骨下动脉起始部(P<0.05);60~69岁组无名动脉分叉部内膜中层增厚及粥样硬化斑病变患病率与颈总动脉分叉部相近(P>0.05),但单独出现比例仍然较高。 结论 超声检查中老年患者颈部血管时,检查无名动脉分叉部有利于提高动脉粥样硬化病变的早期检出率,可为缺血性心、脑血管疾病的早期预防提供依据。 |

| Objective To investigate the morbidity of atheromatous lesions of the innominate artery bifurcation in middle-aged and old people and the significance of ultrasonography. Methods Totally 1619 subjects who underwent ultrasound examination of large cervical vessels were enrolled and divided into 40—49 group, 50—59 group, 60—69 group and ≥70 group. The intima-media thickness (IMT) and the morbidity of atheroma of the innominate artery bifurcation were observed with ultrasound, and lesions of all carotid regions and the initiation site of the subclaviam artery were compared. Results The morbidity of midintimal thickening and atheromatous lesions of the innominate artery bifurcation by ultrasonography in 40—49 group, 50—59 group, 60—69 group and ≥70 group was 10.38% (22/212) 24.63% (50/203), 27.88% (126/452) and 53.85% (343/637), respectively, while the individual detectable rate was 90.91% (20/22), 66.00% (33/50), 32.54% (41/126) and 11.37% (39/343), respectively. The morbidities of midintimal thickening and atheromatous lesions of the innominate artery bifurcation in 40—49 group and 50—59 group were significantly higher than those of all carotid regions and of the initiation site of the right subclavian artery (P<0.05), and the morbidity in 60—69 group approximated to that of the common carotid bifurcation (P>0.05), but the individual occurring proportion remained higher. Conclusion During ultrasonic examination of the cervical vessels in middle-aged and old people, adding the examination of innominate arteryl bifurcation is helpful to increasing early detectable rate of atherosclerotic lesions, therefore providing basis for early prevention of ischemic cardio-cerebrovascular diseases. |
