The aorta is the large, main artery carrying blood away from the heart. Aortic arch syndrome refers to a group of signs and symptoms associated with structural abnormalities in the arteries that branch off from the aortic arch (the top portion of the aorta). The abnormalities are most often associated with atherosclerosis , trauma, blood clots , or malformations that developed before birth. The arteries' defects result in abnormal blood flow to the head, neck, or arms.
