Hi Joy,
An aneurysm is a weakness in the wall of the aorta. This weakness gradually expands, and eventually will blowout,(much like a Ballon bubble on a tire), or it will dissect, or tear along the wall. Aneurysms are often called the silent killer, they often go undected. I believe the normal size of the aorta is 3 cm, My doctor is watching 3 different ones on me. According to the doctors I have spoke with, Aneurysms are monitored, and treated with medication until they reach a size of 5 cm. Once an aneruysm reaches 5 cm or better, it is time to take a more aggressive corrective action which in most cases requires surgery.
You can read up on aneurysms at the following sites.
This site is for people that have had aneurysms. It is composed of narratives from those that have survived. Mine is also on there.
