A brain (cerebral) aneurysm is an abnormal outward bulging or ballooning on the weak area/spot in the wall of an artery that supplies blood to the brain.
Network of blood vessels at the base of the brain called the circle of Willis.
The following risk factors may increase either a person’s risk for an aneurysm or its rupture:
In most of the cases, a brain aneurysm causes no symptoms and goes unnoticed. It may get ruptured (causing a subarachnoid haemorrhage), releasing blood into the skull and causing a stroke, brain damage or even death.
Symptoms of ruptured or unruptured brain aneurysm typically depend upon the location and severity of aneurysm.
The main goal of treatment for brain aneurysm after it gets ruptured is to stop the bleeding and prevent potential permanent damage to the brain and reduce the risk of recurrence. Line of treatment depends upon the age and overall health of the patient, size of the aneurysm and presence of any additional risk factors. Small sized aneurysm are observed as their chances of rupture are low whereas large sized or symptomatic aneurysms need surgery.
The following treatment can be used for both ruptured and unruptured brain aneurysms:
