Persistent hypoglossal artery.
During embryological development, the hypoglossal artery serves as a transient anastomosis between the internal carotid artery and the vertebro-basilar system. This artery occasionally persists into adult life. Two cases of persistent hypoglossal artery we have recently encountered are reported here. The embryology, diagnosis and potential problems for carotid surgery are discussed.
