1:1 scale model of a dissected thoracic aorta.
The ascending aorta, the aortic arch (with the origin of the brachiocephalic trunk, the left common carotid artery and the left subclavian artery) and the descending aorta are depicted. Along all the length of the aorta runs the false lumen, between the inner 2/3 and the outer 1/3 of the vascular wall.
