Case Reports
External carotid stenting for symptomatic stenosis in a patient with patent EDAS for Moyamoya disease.
Moyamoya disease is characterized by progressive narrowing of the internal carotid artery (ICA). Symptomatic patients typically undergo cerebrovascular intervention via extracranial-intracranial (EC-IC) bypass, most often with the use of the superficial temporal artery. This case of Moyamoya disease is of particular interest as the patient presented with a unilateral atherosclerotic external carotid artery (ECA) stenosis after EC-IC bypass that eliminated the benefit of his original surgery, resulting in a symptomatic presentation. ⋯ This case illustrates that a patient presenting with Moyamoya disease and concurrent symptomatic ECA stenosis post-EDAS can be effectively and safely treated with ECA stenting.
