Persistent hypoglossal artery and persistent trigeminal artery presenting with posterior fossa transient ischemic attacks

Abstract

✓ Two patients, one with a persistent hypoglossal artery and the other with a persistent trigeminal artery, presented with transient ischemic attacks in the distribution of the posterior fossa. Both had stenosis and ulcerative plaques at the carotid bifurcation. Their symptoms were successfully relieved after carotid endarterectomy.
