Trigeminal Artery and Hypoglossal Artery

  • A - The most common persistent embryonic carotid-vertebrobasilar anastomosis is the trigeminal artery. A persistent trigeminal artery consists of a connection between the intracranial internal carotid artery and the basilar artery, usually in the basilar midsegment or distally near the origin of the superior cerebellar arteries.
  • B - A rarer variant is the persistence of the hypoglossal artery, which is distinguished from a persistent proatlantal artery because it enters the skull via the hypoglossal canal rather than the foramen magnum.
