How serious is a small aneurysm in the brain?
A ruptured aneurysm quickly becomes life-threatening and requires prompt medical treatment. Most brain aneurysms, however, don’t rupture, create health problems or cause symptoms. Such aneurysms are often detected during tests for other conditions.
Why aneurysm is common in circle of Willis?
Aneurysms associated with subarachnoid hemorrhages tend to occur in a circle of arteries that supply blood to the brain. These are known as the circle of Willis . In some people, a congenital anomaly leads to weak and thin blood vessel walls, increasing the risk of an aneurysm.
Can a small brain aneurysm go away?
Aneurysms develop over a lifetime,” he says. “Another is that an aneurysm can disappear or heal itself. This is very rare and only happens in aneurysms that are considered benign because the flow of blood is so slow it eventually forms a clot and seals off the bulge.”
