Persistent Hypoglossal Artery

Persistent hypoglossal artery is one of the persistent carotid-vertebrobasilar anastomoses. It is present in 0.02-0.26% of individuals ² and overall, is second in frequency to the trigeminal artery which is present approximately six times as often ³.

It arises from the distal cervical internal carotid artery segment, usually between the C1 and C3 vertebral level. After passing through an enlarged hypoglossal canal, it joins the basilar artery inferiorly. If large, the ipsilateral vertebral artery and posterior communicating artery are often hypoplastic or absent.
