高频彩色多普勒结合经胸心脏探头检查在锁骨下动脉盗血综合征的诊断价值

Diagnostic value of high frequency color Doppler combined with transthoracic cardiac probe in subclavian steal syndrome

目的探讨高频彩超联合心脏探头检查在锁骨下动脉盗血综合征的诊断价值。方法选择2011年1月至2016年1月我院收治的80例疑似锁骨下动脉盗血患者为研究对象,所有患者依次进行高频彩超及经胸心脏探头检查,对可疑患者均进行束臂试验检查。结果 80例患者进行束臂试验检查后确诊锁骨下动脉盗血者62例。经10L探头超声诊断锁骨下动脉盗血诊断符合率87.1%(54/62),联合M4S心脏探头检查后,诊断符合率98.4%(61/62),二者比较差异有统计学意义(χ2=4.313,P=0.038)。根据Ⅰ、Ⅱ、Ⅲ级盗血诊断标准,Ⅰ级盗血8例,Ⅱ级盗血20例,Ⅲ级盗血34例。10L探头对Ⅰ级盗血诊断符合率25.0%(2/8),显著低于10L+M4S探头对Ⅰ级盗血诊断符合率87.5%(7/8),差异有统计学意义(P=0.041)。Ⅱ级及Ⅲ级盗血诊断符合率比较,差异无统计学意义(P>0.05)。结论高频彩超联合经胸心脏探头超声检查,可提高对锁骨下动脉盗血综合征诊断率,减少漏诊。

Objective To investigate the diagnostic value of high frequency color Doppler combined with transthoracic cardiac probe in subclavian steal syndrome. Methods We selected 80 cases of suspected subclavian steal patients from January 2011 to January 2016 in our hospital as the subjects,the CDFI and M4 S were performed in 80 suspected patients in turn. Results CDFI detection showed that subclavian steal syndrome were54 cases（ showed that I period steal was 2 cases; II period steal was 18cases; III period steal was 34cases）,after underwent additional with M4 S for arteriae subclavia and innominate artery,there were 60 cases diagnosed as subclavian steal syndrome（ I period steal was6 cases; II period steal was 20cases; III period steal was34 cases）.All of the suspected patients were proved to be subclavian artery steal by brachial artery test.Conclusions High frequency color Doppler combined with transthoracic cardiac probe can complement each other and can reduce the erroneous diagnosis or missed diagnosis.
