Abdominal Aortic Aneurysm
The aorta is the largest blood vessel in
the body and is called the abdominal aorta
as it passes through the abdominal cavity.
An abdominal aortic aneurysm (AAA) occurs
when the walls of the aorta weaken and
become dilated or enlarged. When an
abdominal aortic aneurysm becomes critically
enlarged (greater than 5 cm or about 2
inches) the risk of rupture increases.
Unfortunately, abdominal aortic aneurysms may
not produce symptoms as they enlarge. If a
AAA ruptures the chances of survival is low
with 80 to 90% of all ruptured aneurysms
resulting in death. These deaths can be
prevented if an aneurysm is detected and
treated before it ruptures.
WHAT CAUSES AN ABDOMINAL AORTIC ANEURYSM?
An AAA is most commonly caused by a vascular
disease called atherosclerosis or “hardening
of the arteries”. A number of risk factors
are associated with developing AAA
including:
- High blood pressure
- Tobacco use
- Diabetes
- High cholesterol levels
- Family history of vascular disease
- Obesity
- Physical inactivity
- Male gender
Your risk of developing AAA can be
reduced by modifying or controlling your
risk factors through lifestyle changes and
behavior changes.
FACTS ABOUT AAA
- AAA affects 5-7% of people over
the age of 60
- Males are five times more likely to
have AAA than women
- AAA is the 13th leading cause of
death in the U.S. accounting for
approximately 15,000 deaths each year
- Those at highest risk for AAA are
males over the age of 60 who have a
history of smoking or a history of
atherosclerosis or “hardening of the
arteries “
WARNING SIGNS AND SYMPTOMS
Unfortunately, AAA can develop and enlarge
for years without signs or symptoms until
the aorta is dangerously enlarged. Symptoms
can include:
- severe, intense or sudden back or
abdominal pain
- fast pulse or heart beat
- nausea and vomiting
- weakness and shock
DIAGNOSIS
AAA can be difficult to detect by physical
examination even if the aorta is dangerously
enlarged. Often AAA is detected incidentally by
a medical
imaging test. AAA can easily be
detected by SafeHeart Health Screens
ultrasound screening tests even at an early
stage.
