Ischemic Stroke and Subclavian Steal Syndrome: More than just an incidental finding

Abstract

Introduction: Subclavian steal syndrome occurs due to retrograde flow secondary to ipsilateral subclavian stenosis which leads to hemodynamic changes causing cerebrovascular lesions, specifically in the posterior arterial territory. Case: A patient with acute weakness and hypoesthesia. MRI revealed a stroke in the left middle cerebral artery territory. Further studies reported subclavian steal syndrome. Conclusion: Subclavian steal syndrome is associated with cerebrovascular disease, particularly in the posterior territory, hence, neurologists should be aware of the clinical picture, diagnosis approach and treatment options.
