Subclavian steal syndrome (SSS) is a manifestation of vertebrobasilar artery insufficiency due to stenosis of the proximal subclavian artery. It is a common vascular disorder; however, most patients are asymptomatic, and the disorder is commonly found incidentally during imaging. Nevertheless, some patients may present with arm ischemia or signs and symptoms of vertebrobasilar insufficiency, such as vertigo, dizziness, diplopia, ataxia, dysarthria, and syncopal episodes. We present a case of a male patient who presented with sudden onset dizziness, syncopal episodes, and blood pressure discrepancy between his arms. Diagnosis was a challenge, and the patient underwent several investigations, including basic bloodwork, electrocardiography (ECG), echocardiography, brain computed tomography (CT), and coronary CT angiography (CTA). Narrowing in the proximal left subclavian artery was found during coronary CTA, which confirmed the diagnosis of SSS.
锁骨下动脉窃血综合征（SSS）是由于近端锁骨下动脉狭窄导致椎基底动脉供血不足的一种表现。它是一种常见的血管疾病；然而，大多数患者无症状，该疾病通常在影像学检查时偶然发现。尽管如此，一些患者可能会出现手臂缺血或椎基底动脉供血不足的体征和症状，如眩晕、头晕、复视、共济失调、构音障碍和晕厥发作。我们报告一例男性患者，他突然出现头晕、晕厥发作以及双臂血压差异。诊断颇具挑战性，患者接受了多项检查，包括基础血液检查、心电图（ECG）、超声心动图、脑部计算机断层扫描（CT）和冠状动脉CT血管造影（CTA）。冠状动脉CTA检查发现左锁骨下动脉近端狭窄，这证实了锁骨下动脉窃血综合征的诊断。
