The diagnosis of these lesions is most easily established by CT scan. Biplane arteriography is necessary in order to clearly analyze the aortic arch and its branches. Surgical resection is usually indicated. Numerous procedures have been proposed to treat these lesions and controversy exists concerning the best surgical technique.
