An aortic dissection is an emergency with your aorta, which is the largest blood vessel in your body and the main artery that takes blood from your heart to the rest of your body. During an aortic dissection the inner layer of your aorta tears, letting blood in where it usually doesnât go.
Aortic dissection is a serious condition in which there is a tear in the wall of the major artery carrying blood out of the heart (aorta). As the tear extends along the wall of the aorta, blood can flow in between the layers of the blood vessel wall (dissection). This can lead to aortic rupture or decreased blood flow (ischemia) to organs. Causes. When it leaves the heart, the aorta first moves up through the chest towards the head (the ascending aorta). It then bends or arches, and finally moves down through the chest and abdomen (the descending aorta). Aortic dissection most often happens because of a tear or damage to the inner wall of the aorta.
