A man aged 51 with dextrocardia and right common and internal carotid artery agenesis is described. Cerebral blood flow is allowed internally by the left carotid and left vertebral antegrade flow, while right artery has only the function to drain the blood from the left side of vertebral system. A small external right carotid does exist, but it is separated from the cerebral hemodynamics. Diagnosis of dextrocardia was made on the basis of the standard chest X-ray, that of carotid agenesis on the basis of selective digital arteriography, color-Doppler and magnetic resonance. The diagnosis of congenital agenesis was based on the absence of a foramen caroticus and of a canalis caroticus. Large anasthomosis between the left and right side of cerebral system permit a normal perfusion to left cerebral hemispherium and a quite normal life.

Abstract
A man aged 51 with dextrocardia and right common and internal carotid artery agenesis is described. Cerebral blood flow is allowed internally by the left carotid and left vertebral antegrade flow, while right artery has only the function to drain the blood from the left side of vertebral system. A small external right carotid does exist, but it is separated from the cerebral hemodynamics. Diagnosis of dextrocardia was made on the basis of the standard chest X-ray, that of carotid agenesis on the basis of selective digital arteriography, color-Doppler and magnetic resonance. The diagnosis of congenital agenesis was based on the absence of a foramen caroticus and of a canalis caroticus. Large anasthomosis between the left and right side of cerebral system permit a normal perfusion to left cerebral hemispherium and a quite normal life.Pubblicazioni consigliate
