Aortic arch syndrome

  • Definition

    Aortic arch syndrome refers to a group of signs and symptoms associated with structural problems in the arteries that branch off the aortic arch. The aortic arch is the top part of the main artery carrying blood away from the heart.


    Alternative Names

    Subclavian artery occlusive syndrome; Carotid artery occlusion syndrome; Subclavian steal syndrome; Vertebral-basilar artery occlusive syndrome


    Causes, incidence, and risk factors

    Aortic arch syndrome problems are most often associated with trauma, blood clots, or malformations that develop before birth. The arteries' defects result in abnormal blood flow to the head, neck, or arms.

    In children, there are multiple types of aortic arch syndromes, including:

    • Congenital absence of a branch of the aorta
    • Isolation of the subclavian arteries
    • Vascular rings
