Aneurysms can develop silently due to microscopic changes in the arterial wall, such as inflammation, collagen degradation, and alterations in blood flow. Even in seemingly healthy individuals, factors such as chronic stress, undiagnosed hypertension, or a family history of aneurysms can contribute to their formation and growth.
Myth 5: “All aneurysms rupture.”
Fact: Not all aneurysms rupture, but the risk varies.
Science:
The risk of rupture depends on the size, location, growth rate, and integrity of the arterial wall. For example, larger aneurysms or those located in certain cerebral arteries are more likely to rupture. Doctors may recommend monitoring with imaging tests or preventive treatment (such as surgical clipping or endovascular embolization) based on an individualized risk assessment.
What really happens in an aneurysm?
Essentially, an aneurysm forms when a section of a blood vessel wall weakens and begins to bulge due to pressure. This weakening involves:
Loss of structural proteins (such as collagen and elastin)
Chronic inflammation of the vessel wall
Abnormal blood flow patterns that put pressure on specific points of the artery
