Abdominal Aortic Aneurysm (AAA) Infographic series (1)

What do you need to know about Abdominal Aortic Aneurysm?
Abdominal Aortic Aneurysm (AAA) is becoming more and more common in Hong Kong and is known as a “silent killer” due to its asymptomatic nature. The prevalence of this disease is global. U.S and U.K have seen 15,000 deaths [1] and 6,000 deaths [2] respectively caused by ruptured AAAs. In Hong Kong, more than 1,000 new cases of aortic aneurysm are reported every year. It’s important to increase public awareness and understanding around the disease.


The series will look into:
1: What is Abdominal Aortic Aneurysm (AAA)?
2: How common is AAA?
3: How dangerous is AAA?
4: What are the symptoms?
5: Who will have AAA?
6: How to diagnose AAA?
7: When & how to treat AAA?

An abdominal aortic aneurysm is an abnormally dilated area in the lower part of the aorta within the abdomen [3] . The fact that it is asymptomatic means the aneurysm is often left unnoticed and unattended promptly.

 
How common is AAA?

How dangerous is AAA?

When the aorta becomes dilated, it behaves like blowing up a balloon. When the balloon is too excessively blown up, it will rupture. Usually when the size of aneurysm is >5cm, there is significant risk of rupture. Rupture AAA can cause massive bleeding within short period of time.

The overall mortality rate of a ruptured aneurysm can be as high as 100% and the risk of rupture increases as the size of the aneurysm expands. Once internal bleeding is caused by the rupture of aneurysm, it becomes a life-threatening condition.
