Abstract:
Objective To explore the clinical value of scanning the initial segment of right subclavian artery routinely in carotid artery ultrasonography, thus to increase the detectable rate of arteriosclerosis.Methods 2 896 subjects who had undergone carotid artery ultrasonography were analyzed retrospectively from November 2010 to June 2015 in Shuishang Park Hospital,Tianjin.The initial segment of right subclavian artery had been examined rou-tinely in carotid artery ultrasonography from February 2013.The detectable rate of arteriosclerosis at the carotid artery was compared in the two groups.The detectable rate of arteriosclerosis at the bifurcation of common carotid artery and the initial segment of right subclavian artery was analyzed and compared in different age -groups from February 2013 to June 2015 ( group B ) .Results The detectable rate of arteriosclerosis at the carotid artery in group B (74.21%) was significantly higher than 57.34%of group A(χ2 =91.82,P=0.000).The detectable rate of arterio-sclerosis at the carotid artery in group B was increased by age ( the initial segment of right subclavian artery χ2 =181.829,P=0.000;the bifurcation of common carotid arteryχ2 =635.298,P=0.000).The detectable rate of arteri-osclerosis at the initial segment of right subclavian artery was higher than that of the bifurcation of common carotid artery in group of age 36-45 years and >45-55 years (the group of age 36-45 years χ2 =8.988,P=0.003;the group of age >45-55 yearsχ2 =19.507,P=0.000).Conclusion It is necessary that examining the initial seg-ment of right subclavian artery routinely in carotid artery ultrasonography to increase the detectable rate of arterioscle-rosis,and the initial segment of right subclavian artery is the important part to find the arteriosclerosis of carotid artery early,it is of guiding significance to prevent cardiovascular and cerebrovascular disease.
