Abstract

OBJECTIVE: Atherosclerotic stenosis or obstruction of the innominate artery is rare. Traditional surgical management is a technically demanding intervention with acceptable, but not negligible, rates of morbidity and mortality. Endovascular approaches to supraaortic lesions have been successful and are now the preferred treatment for stenoses of the brachiocephalic vessels. The use of cerebral protection devices in subclavian and innominate interventions is less established. CLINICAL PRESENTATION: A 58-year-old woman had Takayasu giant cell arteritis with a history of a left middle cerebral artery stroke 3 weeks after undergoing placement of a left common carotid artery (CCA) stent and right innominate artery stent in 1998. She recently presented with worsening dizziness, ataxia, and right arm numbness and was referred to the endovascular neurosurgery service for management. INTERVENTION: Initial angiography revealed left CCA stenosis and right innominate occlusion. The patient initially underwent left CCA angioplasty, planned as a staged procedure. This was followed by recanalization of the right innominate artery through an approach using both femoral arteries and the right brachial artery. This 3-site technique allowed simultaneous distal protection of both the right cervical vertebral and carotid arteries. CONCLUSION: Reopening a chronically occluded innominate artery risks an embolic shower through both the right vertebral and carotid arteries. Using multiple sites of arterial access, distal protection devices can be deployed in both the cervical vertebral and carotid arteries to reduce the risk of stroke.
