Hi Marietjie,
There is no specific laboratory study that exists to make the diagnosis of abdominal
aortic aneurysm (AAA).
Ultrasonography, plain radiography, CT scan, MRI, and angiography can only aid in the diagnosis of AAA.
If you strongly feel that you have AAA, you must get it checked before it is too late. Yes, it can be dangerous to not be examined.
The causes for it is peripheral
atherosclerotic vascular disease, COPD, coronary artery disease,
hypertension and few other less common causes.
The prognosis is very much guarded for someone who has a rupture outside the hospital. More than 50% do not survive to the emergency department; of those who do,
survival rate drops by about 1% per minute.
I hope this information clarifies your doubts.
Please get yourself evaluated if in doubt.
Take care and regards,
