Abdominal Aortic Aneurysms
What is an aneurysm?An aneurysm is an abnormal dilatation of the wall of a blood vessel that is 50% greater than the artery's normal diameter (width). An aneurysm may be located in many areas of the body, such as the blood vessels of the brain, the aorta (the largest artery in the body), the intestines, the kidneys, the spleen, and the vessels in the legs.
An aneurysm may be located in one of these areas and/or may be continuous throughout the aorta. An aneurysm called a thoracoabdominal aneurysm involves a thoracic aortic aneurysm extending down to the abdominal aorta. An abdominal aortic aneurysm is located in the abdomen area.
The shape of an aneurysm is described as being fusiform or saccular, which helps to identify a true aneurysm. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the blood vessel. A saccular-shaped aneurysm bulges or balloons out only on one side. Because an aneurysm may continue to increase in size, along with progressive weakening of the artery wall, surgical intervention may be needed. Preventing rupture of an aneurysm is one of the goals of therapy. The larger an aneurysm becomes, the greater the risk of rupture (bursting). With rupture, life-threatening hemorrhage (uncontrolled bleeding) may result. What are the causes of aortic aneurysms?Thoracic aortic aneurysms may be caused by different disease processes, especially in respect to their location.
Descending Thoracic and Abdominal Aortic Aneurysm - Atherosclerosis is most often associated with descending aneurysms and is thought to play an important role in aneurysmal disease. The following risk factors associated with atherosclerosis such as:

What are the symptoms of an aneurysm?
Aortic disease is often insidious. Most people with aortic aneurysms experience no symptoms; their aortic condition is discovered incidentally while being tested for other reasons.
When present, symptoms may including constant pain in abdomen, chest, back or groin area; a pulsatile mass in the abdomen. The symptoms of an aneurysm may resemble other medical conditions or problems, including heart attacks, pneumonia, and digestive conditions.

How are aneurysms diagnosed?For most people, their aortic condition is discovered incidentally while being tested for other reasons. For patients suspected to have aortic disease, selection of a type of diagnostic examination is related to the location of the aneurysm. In addition to a complete medical history and physical examination, diagnostic procedures for an aneurysm may include any, or a combination, of the following:
|
Aortic Root Aneurysm and Asceneding Aortic Aneurysm on CT Scan
Aortic Root Aneurysm and Ascending Aortic Aneurysm on CT Reconstruction
Aortic root aneurysm on echocardiogram

What are the possible treatment for aortic aneurysms?
Treatment options for an amort aneurysm may include one or more of the following:
-- controlling blood sugar in those with diabetics,
-- weight loss if those overweight or obese and
-- controlling dietary fat intake
-- high blood pressure
Specific treatment will be determined by your physician based on:
- Controlling or modifying risk factors steps such as:
-- controlling blood sugar in those with diabetics,
-- weight loss if those overweight or obese and
-- controlling dietary fat intake
- Medication: to control factors such as:
-- high blood pressure
- Surgery, typically the diseased area of the aorta is replaced with a fabric graft
- Stent graft or endograft which is comprised of a layer of impermeable reinforcement material enclosed by a self-expanding metal support mesh and is placed across the aneurysm site
Specific treatment will be determined by your physician based on:
- age, overall health and medical history
- size and extent of the disease
- signs and symptoms
- tolerance of specific medications, procedures or therapies
- expectations for the course of the disease
- patient preference
How do I prevent an aortic dissection and/or further growth of my aneurysm?
Here are a few tips:

- Control your blood pressure. If you have high blood pressure, get a home blood pressure measuring device to help you monitor and keep your blood pressure well controlled.
- Don't smoke. Or, if you do, take steps to stop.
- Maintain an ideal weight. Follow a low-salt diet, low fat, high fiber diet, and exercise regularly.
- Watch your cholesterol. Keep your cholesterol levels within a range that is recommended by your doctor.
- Continue low-impact exercise (eg brisk walking). If you have an aneurysm or are predisposed, avoid high-impact exercise that significantly increases your blood pressure (eg weight training)
- Wear a seat belt. This reduces the risk of traumatic injury to your chest area.
- Keep your doctor well-informed. If you have a family history of aortic dissection, let your doctor know.
