An aortic dissection is a tear in your aorta. The aorta is the main blood vessel that carries blood out of your heart to supply the rest of your body. It comes out of your heart and curves around, then goes down through your chest (thoracic aorta) and into your belly (abdominal aorta). The wall of the aorta has inner and outer layers.
Aortic dissection occurs most often in the thoracic aorta. This is more likely to happen if the inner layer of the aorta has a weak spot or gets injured. As the dissection widens and blood flows through it, the aorta becomes “double-barreled.” This means one part of the aorta continues to carry blood. However, the inner wall begins to separate from the rest of the aorta as blood flows through the tear. The torn part of the aorta fills with blood. It swells up like a balloon. This can reduce blood flow through the part of the aorta that is still working. …show more content…
