CONGENITAL ABSENCE OF THE INTERNAL CAROTID ARTERY ASSOCIATED WITH CEREBRAL HEMIATROPHY, ABSENCE OF THE EXTERNAL CAROTID ARTERY, AND PERSISTENCE OF THE STAPEDIAL ARTERY

Unilateral congenital absence of the internal carotid artery, either partial or total, has been rarely demonstrated. We are presenting 1 case of each entity.

The case of partial absence is unique in that it is felt to represent the first known case of demonstration of a vascular etiology of primary cerebral hemiatrophy in a living patient.

The case of unilateral total absence of the internal carotid was associated with contralateral absence of the external carotid artery and persistence of the stapedial artery which were incidental findings in a patient who presented with a subdural hematoma following head trauma.
