The frequency of radiologically demonstrable subclavian or innominate artery stenosis is approximately up to 17%. Of these, 2.5% have angiographic flow reversal in vertebral artery. Only 5.3% of those with angiographic steal have neurologic symptoms [3]. Treatment is indicated only in this small percentage of symptomatic patients. The symptoms are induced by exercise or exertion using the arm ipsilateral to stenosis. We describe a case with concurrent right vertebral artery (VA) pseudoaneurysm and left subclavian artery (SCA) stenosis, where the pattern of symptoms was suggestive of embolic etiology rather than exercise induced. An unusual presentation of SCA stenosis is highlighted, that resolved with endovascular intervention. The management in the presence of concurrent VA pseudoaneurysm is briefly discussed.
