[ArchivalUser]

sorry ...asymptomatic...

[ArchivalUser]

should we confirm Abdominal Aortic Aneurysm via imaging----

or Physical examination is enough.....

[ArchivalUser]

how can you determine exact size on physical exam ...you need USG fro that

[ArchivalUser]

suppose they measure roughly on Physical exam AAA ---4cm-----then......CTscan/USg

Archer say------CT is for Dx
USG is for Screening & f/U

i a;m confused -----any input

male smoker more 65 y/o one time U/A for screening AAA. first degree family histroy is big predictor of AAA. if AAA less than 4 cm ----- U/A q 2-3 years, If AAA is 4 cm U/A-----U/A q 6 months and if Size 5.5 cm or progress more .5 cm q6 months do elective surgery, If there is sign of rupture, like low back pain,shock, peritoneal sign order CT and send pt to OR with surgery consult.

I suppoused needs to be US just to confirm. Then CT in next follow ups for accurate measures

Aorta is the blood vessels which connects from chest to abdomen. It is the longest and the main blood vessel in our body. The main function of Aorta is it carries blood from the heart and supplies to the rest of the body. The part of the aorta
in your abdomen is called the abdominal aorta. It supplies blood to your stomach, pelvis and legs.

The weakest part of the blood vessel is called aneurysm. When the blood vessels are weak they will swell and look like a bal1oon. If an aneurysm forms on your abdominal aorta and grows too large, your aorta may tear or burst.

Abdominal aortic aneurysms affect 5% of elderly men who have smoked. The relative risk is substantially increased for men with a first-degree family member affected by abdominal aortic aneurysm. The risk tends to be lower in women than in men, although less is understood about the natural history of abdominal aortic aneurysm in women. Common symptoms associated with threat of rupture include back pain, vague abdominal pain, or an abdominal mass that is painful to palpation; however, most patients remain asymptomatic for many years. The mortality rate associated with rupture of an abdominal aortic aneurysm approaches 80%. The annual rate of rupture of abdominal aortic aneurysms smaller than 5 cm in transverse diameter is 5% or less per year. For each increase in diameter of 1 cm, the annual event rate increases by approximately 10%.

Most small aneurysms enlarge slowly, but the rate of expansion increases as aneurysms dilate. For example, most aneurysms less than 4 cm in diameter enlarge by less than 0.2 cm per year. A typical rate for an aneurysm greater than 4.5 cm in diameter is 0.35 cm per year.
