title: Primitive hypoglossal artery and carotid endarterectomy.
abstract: A patient with transient ischemic symptoms in the carotid and vertebrobasilar distribution is reported. His arteriogram demonstrated a persistent primitive hypoglossal artery which in part may explain the clinical picture. The embryology, radiology, clinical manifestations, and surgical considerations of this rare anomaly are discussed.
