A rare anomalous origin of left subclavian artery from the circle of Willis in combination with right sided aortic arch: A case report

Abstract

BACKGROUND: One of the rare aortic congenital abnormalities is right sided aortic arch which is occurred in approximately 0.1% of the population. The anomalous origin of the subclavian arteries has also been reported.

CASE REPORT: In this study, a case of a right-sided aortic arch with anomalous left subclavian artery origin from the cerebral arteries is presented which was diagnosed in Computed tomography angiogram (CT angiogram) and angiography of a 10-year-old boy referred due to recurrent chest pains during two weeks before admission and pulselessness of his left upper limb and left carotid artery.

CONCLUSION: Many of the congenital vascular anomalies may have no obvious signs or symptoms and therefore the exact history and physical examination could help us in better diagnosis. Besides, some of these anomalies are associated with other abnormalities of other body organs particularly the cardiac system.
