An Abdominal Aortic Aneurysm is an enlarged area in the lower part of the major
vessel that supplies blood to the body (Aorta). The Aorta runs from the heart through
the center of the chest and abdomen.  

 The Aorta, **the largest artery** in the body, is a blood vessel that **carries
oxygenated blood away from the heart**. It originates just after the **aortic valve**
connected to the left side of the heart and extends through the entire chest and
abdomen.

 The portion of the aorta that lies deep inside the abdomen, right in front of the
spine, is called the **abdominal aorta**. **An Abdominal** **Aortic Aneurysm (AAA,
or “Triple A”) **occurs when this type of vessel weakening happens in the portion
of the aorta that runs through the abdomen.

 Since it is the largest blood vessel in the body, a ruptured **abdominal aortic
aneurysm **can cause **life-threatening bleeding.**

 **AAA** has few noticeable symptoms. Hence, comes in the ultrasound scanning a 
highly accurate way to measure the size of an aneurysm. 

###  **Which ultrasound scanner is used for abdominal aortic aneurysm assessement?**

 A physician may use the **Doppler ultrasound** **[SIFULTRAS-5.34](https://sifsof.com/product/linear-wireless-ultrasound-scanner-sifultras-5-34/)**
to examine blood flow through the aorta.  Portable ultrasound scanners can quickly
and accurately identify an Abdominal Aortic Aneurysm when performed by appropriately
trained emergency medicine providers.    

 Moreover, it is the leading modality in monitoring the** AAA **throughout a period
that usually goes **up to 12 months.**

 Ultrasound imaging of the aorta is useful for measuring its size to screen for 
AAA. In addition to screening, ultrasound is also a useful tool after the diagnosis
of AAA to monitor its size on a regular basis to see if it needs to be repaired.

 This ultrasound shows normal anatomy of the aorta in short axis. Criteria for making
the diagnosis of abdominal aortic aneurysm include the following: focal dilatation
of the abdominal aorta >3.0 cm; increase in the aortic diameter to 1.5 times the
normal expected diameter; and ratio of infrarenal to suprarenal aortic diameter 
≥1.2.

There may be variations in measurement of the aneurysm size depending on technique.
The aneurysmal sac should be measured from outer wall to outer wall with a longitudinal
image. The transverse diameter should be measured perpendicular to the long axis
of the aorta.

aortic aneurysm when performed by appropriately trained [emergency medicine providers](https://sifsof.com/product-category/doctor-specialties/emergency-medicine-specialist/).
