Aortic arch syndromeDefinitionAortic arch syndrome refers to a group of signs and symptoms associated with structural abnormalities in the arteries that branch off the aortic arch (the top portion 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 CausesThe abnormalities are most often associated with atherosclerosis, trauma, blood clots, or malformations that developed before birth. SymptomsThe arteries' defects result in abnormal blood flow to the head, neck, or arms. Symptoms vary according to the affected artery, but may include neurologic changes (such as dizziness, blurred vision, weakness, and transient ischemic attacks), blood pressure changes, reduced pulse, numbness of an arm, and others. TreatmentSurgery is usually required to treat the underlying cause of aortic arch syndrome. Illustrations and Images
