What if an aneurysm ruptures? This happens if the wall of the artery thins excessively or the blood pressure rises significantly. As a reminder, an aneurysm is a bulge in the wall of a vessel (almost always an artery); an aneurysm of the heart is also possible. Since vessels exist at every point in our body, aneurysms may be anywhere. Still, the most common location is in the brain. And if an aneurysm ruptures in it, it will lead to a massive hemorrhage in the tissue of the organ. Such consequences cause serious damage to the brain and have a 70% chance of being fatal☝🏻
