Congenital septation of the aortic arch with carotid stenosis

Department of Cardiac Surgery, Oxford Heart Centre, England.
A 14-year-old white boy presented with syncope and a left carotid bruit.
Arch aortogram showed narrowing of the distal aortic arch, left carotid
stenosis, and small left subclavian and vertebral arteries. When aortic
arch replacement was carried out a vertical septum was found in the distal
arch. Histologic examination suggested this was ductal in origin.
