What Actually Happens in an Aneurysm?
At its core, an aneurysm forms when a weakened section of a blood vessel wall begins to bulge outward under pressure. This weakening involves:
- Loss of structural proteins such as collagen and elastin
- Ongoing inflammation in the vessel wall
- Abnormal blood flow patterns that place stress on specific areas of the artery
Over time, the wall may become so thin that it ruptures, leading to potentially life-threatening bleeding.
