Introduction Subclavian steal syndrome is a phenomenon of arterial flow reversal secondary to occlusive disease in proximal subclavian arteries, occasionally resulting in neurologic sequelae. Case Presentation The authors present the case of a 67-year-old man with stroke risk factors and a history of receiving head and neck radiation therapy who developed subclavian steal physiology leading to a transient ischemic attack and posterior circulation stroke. He was medically optimized without substantial progression or recurrence of disease. Conclusion This case illustrates a case of vertebrobasilar transient ischemic attack and posterior circulation stroke from subclavian steal syndrome in the setting of prior radiation therapy manifesting as extremity weakness and discoordination. Further research on therapeutic radiation dosages and subsequent incidence of arterial disease which could contribute to subclavian steal syndrome is necessary.
介绍 锁骨下窃血综合征是由于近端锁骨下动脉阻塞性疾病导致的动脉血流反向的现象，偶尔会导致神经后遗症。
病例介绍 作者报告了一例 67 岁男性病例，有中风危险因素和接受头颈部放射治疗的病史，发生了锁骨下窃血生理现象导致短暂性脑缺血发作和后循环卒中。他经过药物治疗优化后，疾病没有实质性进展或复发。
结论 本病例说明了一例由于先前的放射治疗导致的锁骨下窃血综合征引起的椎基底动脉短暂性脑缺血发作和后循环卒中的病例，表现为肢体无力和协调障碍。需要进一步研究治疗性放射剂量和随后可能导致锁骨下窃血综合征的动脉疾病的发生率。
