- What is a "Dissection Aneurysm"?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: We recently lost a good friend to a condition called "a Dissection
- Aneurysm". It was sudden and unexpected, and we have been provided very
- little explanation by his family. Would you please discuss this condition,
- and tell us what might have been done to save his life?

- ANSWER: The definition of an aneurysm is "a sac formed by the widening
- (dilatation) of the wall of a vein, artery or the heart". My guess from the
- information contained in your letter was that you friend suffered from an
- aneurysm of the aorta, the largest artery in the body, and died when the
- aneurysm ruptured. This is the most common outcome for such a situation, and
- occurs in about 70 percent of the cases. More astounding, the diagnosis of
- the aneurysm is usually not known before the life threatening crisis occurs.
- There are many causes of aneurysms, most frequently arteriosclerosis in older
- people, but a frequent cause of death in younger people who have Marfan's
- Syndrome. Whatever the underlying reason, the wall of the vessel is weakened,
- and gradually stretches into a balloon-like formation, pushed by the pressure
- of the blood within the vessel. This can occur without symptoms of any kind,
- although pain may be felt in the area of the aneurysm. Sometimes symptoms
- such as hoarseness and wheezing can result from pressure on the nerves or
- other structures caused by the growing sac. X-rays are helpful in diagnosing
- the condition, but it takes a special technique called "aortography" to find
- the location of a suspected aneurysm. A "dissecting aneurysm" occurs when the
- inner lining of the aorta becomes torn. The blood clot which forms pushes its
- way between the layers of the weakened wall of the vessel, separating them or
- "dissecting" them. This can continue over a period of time, until the outer
- wall breaks, and rupture occurs. Dissecting aneurysms are extremely painful
- for most patients, who describe the pain as being of a "ripping" or "tearing"
- character in the chest for thoracic aneurysms, and frequently taken for a
- heart attack. When an acute dissection occurs, the only treatment available
- with any chance of saving the patient is surgery to repair the tear, usually
- with a graft.
