This 3D medical animation show the cause, and potential locations of aortic aneurysms and the formation of an aortic dissection. The aorta is the largest artery in your body. Your aorta is divided into two main sections: the thoracic aorta and the abdominal aorta. The thoracic aorta has four parts: the aortic root, ascending aorta, aortic arch, and descending aorta.
Over time, degenerative disease may cause the media layer to break down, weakening the wall of your aorta. Blood pumping against the weakened area may cause it to bulge outward like a balloon, forming an Aortic Aneurysm. Further damage to the intimate can allow blood to move through the intimate separating it from the media, forming a flap called the septum between the true aortic channel and the false channel.
From there the blood may break through the outer layer of the aortic wall, causing a life threatening condition or it may re-enter the aorta through another tear in the intima.
