CTA联合TCD评价锁骨下动脉盗血综合征血流动力学变化与诊断价值

Evaluation of Hemodynamic Changes and Diagnostic Value of CTA Combined with TCD in Subclavian Steal Syndrome

目的:观察锁骨下动脉盗血综合征(SSS)采用CTA联合TCD检查的诊断价值,分析血流动力学变化。方法:选取2018年7月~2019年8月拟诊SSS患者48例,均进行数字减影血管造影(DSA)、经颅多普勒超声(TCD)、CT血管造影(CTA)检查,分析检查结果。结果:48例患者中,有44例经DSA检查确诊为SSS。CTA诊断锁骨下动脉或无名动脉狭窄程度同DSA的诊断结果一致性较高(P<0.05)。TCD诊断SSS分期同DSA对锁骨下动脉或无名动脉狭窄程度诊断为正相关(P<0.05)。结论:CTA联合TCD可对SSS血流动力学变化进行准确评价。

Objective:To observe the diagnostic value of subclavian artery steal syndrome(SSS)with CTA combined with TCD,and to analyze hemodynamic changes.Methods:A total of 48 patients with SSS from July 2018 to August 2019 were selected,all of whom were examined by digital subtraction angiography(DSA),transcranial Doppler ultrasound(TCD),and CT angiography(CTA)for analysis and inspection result.Results:44 cases were diagnosed as SSS by DSA.The degree of stenosis of subclavian artery or innominate artery diagnosed by CTA was consistent with DSA(P<0.05).The SSS stage of TCD Diagnosis was positively correlated with DSA diagnosis of subclavian artery or innominate artery stenosis(P<0.05).Conclusions:CTA combined with TCD can accurately evaluate the hemodynamic changes of SSS.
