carotid angioplasty and stenting in a patient with severe internal carotid artery stenosis associated with occlusion of the vertebral and contralateral carotid arteries

Severe internal carotid artery (ica) stenosis is a common cause of cerebrovascular accident (cva) in middle-aged patients. contralateral carotid occlusion (cco) in patients with severe ica stenosis is associated with high risk of cva. carotid endarterectomy (cea) is associated with more complications in patients with cco than those without cco. in this study, we present the case of a 61-year-old patient who presented with multiple transient ischemic attack and severe ica stenosis associated with cco and occlusion of vertebral arteries. the patient was treated successfully with carotid angioplasty and stenting.
