摘要
目的探讨动脉粥样硬化所致的锁骨下动脉盗血综合征(SSS)椎动脉内血流动力学改变。方法选取中国科学技术大学附属第一医院2018-01—2019-11经超声检查发现SSS患者47例,测量锁骨下动脉狭窄程度并比较各型之间椎动脉管腔内径及收缩期峰值血流速度(PSV)。结果Ⅰ型、Ⅱ型及Ⅲ型SSS病变部位比较差异无统计学意义(P>0.05)。各型SSS与患侧锁骨下动脉狭窄程度呈正相关(P<0.05),相关系数rs为0.1195%CI(0.07~0.15)。Ⅰ型及Ⅱ型SSS管腔内径健侧大于患侧,PSV健侧快于患侧;Ⅲ型SSS管腔内径健侧与患侧差异无统计学意义(P>0.05),但PSV健侧快于患侧反向PSV。健侧各型SSS之间管腔内径比较差异无统计学意义(P>0.05),PSV比较Ⅲ型快于Ⅰ型。患侧各型SSS之间管腔内径两两之间比较Ⅲ型大于Ⅰ型,PSV比较Ⅲ型快于Ⅰ型。结论锁骨下动脉狭窄程度与SSS的类型呈正相关,SSS的类型与盗血通路通畅性密切相关。
Objective To investigate hemodynamic changes in vertebral arteries of atherosclerotic subclavian artery steal syndrome(SSS).Methods A total of 47 cases of SSS were selected from the First Affiliated Hospital of University of Science and Techology of China from January 2018 to November 2019.The degree of subclavian stenosis was measured by ultrasonography,and the vertebral artery lumen diameter and peak systolic blood flow velocity(PSV)were compared among types.Results There was no significant difference in the types of SSS of typeⅠ,typeⅡ,and typeⅢ(P>0.05).Each type of SSS was positively correlated with the degree of stenosis of the ipsilateral subclavian artery(P<0.05).The correlation coefficient rs was 0.11(95%confidence interval(0.07~0.15)).Luminal diameter of typeⅠand typeⅡwas larger than that of affected side,and PSV of nomal side was faster than that of affected side.Luminal diameter of TypeⅢwas not significantly different from that of affected side(P>0.05).Howerer,PSV of normal side was faster than that of affected side PSV.There was no significant difference in the luminal diameter between the different types of SSS on the normal side(P>0.05),but the PSV of typeⅢwas faster than the typeⅠ.The luminal diameter of typeⅢon the affected side was larger than that of typeⅠ,and the PSV of typeⅢwas faster compared with typeⅠ.Conclusion The degree of subclavian arterial stenosis is positively correlated with the type of SSS,and the type of SSS is closely related to the patency of blood stealing pathways.
