An Aortic Dissection is a serious condition in which the inner layer of the aorta, the large blood vessel branching off the heart, tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate (dissect). If the blood-filled channel ruptures through the outside aortic wall, aortic dissection is often fatal.Aortic dissection is relatively uncommon. The condition most frequently occurs in men in their 60s and 70s. Symptoms of aortic dissection may mimic those of other diseases, often leading to delays in diagnosis. However, when an aortic dissection is detected early and treated promptly, the chance of survival greatly improves.
-Aortic dissection symptoms may be similar to those of other heart problems, such as a heart attack.
Typical signs and symptoms include:
- Sudden severe chest or upper back pain, often described as a tearing, ripping or shearing sensation, that radiates to the neck or down the back
- Sudden severe abdominal pain
- Loss of consciousness
- Shortness of breath
- Sudden difficulty speaking, loss of vision, weakness or paralysis of one side of your body, similar to those of a stroke
- Weak pulse in one arm or thigh compared with the other
- Leg pain
- Difficulty walking
- Leg paralysis
When to see a doctor
-If you have signs or symptoms such as severe chest pain, fainting, sudden onset of shortness of breath or symptoms of a stroke, seek emergency medical assistance.These signs and symptoms don't always indicate a serious problem, but it's best to get checked quickly. Early detection and treatment may help save your life.
-An aortic dissection is a medical emergency requiring immediate treatment. Therapy may include surgery or medications, depending on the area of the aorta involved.
Type A aortic dissection
-Treatment for type A aortic dissection may include:
- Surgery. Surgeons remove as much of the dissected aorta as possible, block the entry of blood into the aortic wall and reconstruct the aorta with a synthetic tube called a graft. If the aortic valve leaks as a result of the damaged aorta, it may be replaced at the same time. The new valve is placed within the graft used to reconstruct the aorta.
- Medications. Some medications, such as beta blockers and nitroprusside (Nitropress), reduce heart rate and lower blood pressure, which can prevent the aortic dissection from worsening. They may be given to people with type A aortic dissection to stabilize blood pressure before surgery.
Type B aortic dissection
-Treatment of type B aortic dissection may include:
- Medications. The same medications that are used to treat type A aortic dissection may be used without surgery to treat type B aortic dissections.
- Surgery. The procedure is similar to that used to correct a type A aortic dissection. Sometimes stents â€” small wire mesh tubes that act as a sort of scaffolding â€” may be placed in the aorta to repair complicated type B aortic dissections.
-After treatment, you may need to take blood pressure lowering medication for life. In addition, you may need follow-up CTs or MRIs periodically to monitor your condition.
