Objective To evaluate and investigate the clinical value of transcranial Doppler (TCD)in the di-agnosis of subclavian steal syndrome (SSS),and the relationship with digital subtraction angiography (DSA)examination.Methods The data of 79 cases with SSS were reviewed.Among them,37 patients were underwent DSA examination,the results of TCD and DSA were compared.Results Among 79 pa-tients with SSS,there were 23 cases of phase Ⅰ subclavian steal (29.1%),36 cases of phase Ⅱ subclavian steal (45.6%),20 cases of phase Ⅲ subclavian steal (25.3%).The DSA tests of 37 SSS cases showed that,4 cases (10.8%)was suffered from mild stenosis in subclavian artery (SubA),13 cases with moder-ate stenosis (35.1%),14 cases with severe stenosis (37.8%),6 patients (16.2%)with complete occlusion. There was positive correlation (r =0.81,P <0.001)between stenosis in SubA with DSA examination and the extend of subclavian steal with TCD examination.Conclusion TCD is a noninvasive diagnosis and sen-sitive screening method for SSS.It can provide a reliable avenue for early diagnosis and treatment for SSS.%目的：探讨经颅多普勒超声（TCD）诊断锁骨下动脉盗血综合征（SSS）的临床应用价值及与数字减影血管造影（DSA）检查的关系。方法回顾性分析79例 TCD 诊断为 SSS 患者的临床、超声影像学资料，其中37例患者另行 DSA 检查，对比分析 TCD 与 DSA 的检查结果。结果79例 SSS 患者中Ⅰ期盗血23例（29．1％），Ⅱ期盗血36例（45．6％），Ⅲ期盗血20例（25．3％）；37例 SSS 患者行 DSA 检查结果显示锁骨下动脉（SubA）轻度狭窄4例（10．8％），中度狭窄13例（35．1％），重度狭窄14例（37．8％），闭塞6例（16．2％）。TCD 检查发现的盗血程度与DSA 检查所示的 SubA 狭窄程度呈正相关（r ＝0．81，P ＜0．001）。结论TCD 是诊断 SSS 无创、敏感的首选检查方法，可为临床早期诊断和治疗提供了可靠的依据。
