Dissection is catastrophic form of arterial disease. I usually involves the aorta or a portior of it (aortic dissection). Dissection means that layers of the wall of the aorta separate. The inner layer peels off from the remainder of the vessel so that blood can be forced between the layers, extending the dissection along the involved artery.Causes of Dissection. Aortic dissection tends to occur in persons with high blood pressure. There is also some association with diseases that cause general defects in the structural tissue of the body such as a hereditary syndrome called Marfan’s syndrome, abnormalities of the blood vessel walls such as cystic medial necrosis, certain types of atherosclerotic plaques that burrow into the heart vessel wall, certain types of arteritis (inflammation of arteries), bicuspid aortic valve (two cusps instead of the normal three), and pregnancy.Symptoms of Dissection. Dissection of the aorta causes sharp and tearing chest and back pain. Often the pain is focused in the back between the shoulder blades, although it may descend into the lower back as well or feel as if it is “boring” into the chest. Typically the pain is severe and comes on suddenly. It can be vague or like angina, and it is sometimes misinterpreted at first by both patients and doctors as a heart attack.*198\252\8*
