Symptomatic internal carotid artery stenosis in the presence of a persistent primary hypoglossal artery.

Treatment of symptomatic carotid artery stenosis in the presence of persistent primitive hypoglossal artery is challenging. Management should be driven by patients' co-morbidities, the anatomical localization of the lesions and local expertise. In the case of a high origin of the persistent primary hypoglossal artery, carotid artery stenting with the use of a proximal cerebral protection device is probably the preferred and simplest approach.
