THORACIC DISEASES: TYPE A DISSECTION
An aortic dissection is a condition that causes sudden and severe pain in the chest, back or belly. It involves the aorta, which is the main blood vessel that comes out of the heart and carries blood to the body. An aortic dissection can happen anywhere in the aorta. When it involves the first part of the aorta close to the heart, the ascending aorta, it is called a Type A Dissection.
In an aortic dissection, there is a tear in the inner wall and blood runs in between the layers that make up the wall of the aorta. This predisposes the aorta to bursting. Change in the pattern of flow due to the tear can result in any of the body’s organs not receiving enough blood flow.
Type A Dissections of the thoracic aorta are a medical emergency requiring immediate intervention. Many people who have a Type A aortic dissection don’t survive, even with treatment.
What are the Symptoms?
Patients have described ripping chest pain from the center of the chest radiating to the back, between the shoulder blades, is a classic symptom of Type A dissections. Sometimes patients may describe mild pain in the chest, back or groin and it is easy to dismiss these cases as being musculoskeletal pain. Fainting can also be a common symptom and is associated with increased mortality.
