Abstract
Conventional arteriography in an 11-month-old boy with cardiopathy, aortic arch coarctation and haemangiomas showed the absence of the right internal carotid and vertebral arteries, hypertrophy of the right external carotid artery, with enlargement of the internal maxillary and ophthalmic arteries that supplied the right cerebral hemisphere. An MRI study showed an infarcted area in the posterior zone of the left cerebral hemisphere vascularised by the middle cerebral artery that was caused by a thrombosis during a severe bout of gastroenteritis. MRA studies performed at 16 and 23 years of age revealed progressive narrowing of the left carotid and vertebral arteries, persistence of the proatlantal and trigeminal arteries, and poor cerebral vascularisation that, at adult age, was entirely supplied through collateral arteries, branches of both external carotids, the presence of unilateral duplication of the vertebral arteries and ascending pharyngeal artery.
