A brain aneurysm forms within the brain. It is a protrusion in a blood vessel due to the weakening in its wall, usually where it branches. When blood moves via this weakened area, the blood pressure causes a small region to protrude outwards the same as a balloon.
Most brain aneurysms only cause noticeable indications if they rupture. Once this occurs, it is called as subarachnoid hemorrhage which is a critical condition due to the extensive brain damage it causes. This is a medical emergency that requires immediate medical attention.
Why does it develop?
It is still vague what causes the blood vessel wall to weaken, but certain risk factors have been identified such as:
- High blood pressure
- Smoking
- Family history of brain aneurysm
Most brain aneurysms only cause noticeable indications if they rupture.
In some instances, a brain aneurysm forms due to weakening in the blood vessel wall at birth.
Management of a brain aneurysm
If a brain aneurysm is detected before it breaks, the treatment is aimed in preventing its rupture in the future. Most aneurysms do not rupture; thus, treatment is only required if the risk for rupture is exceedingly high.
Certain factors that affect whether treatment is required include:
- Age
- Size and position of the aneurysm
- Family medical history
- Presence of other health conditions
In case treatment is suggested, this generally involves filling the aneurysm with miniature metal coils or an open surgery to seal it using a small-sized metal clip
If the individual is considered low-risk, regular check-ups is necessary to monitor the brain aneurysm. Medications are also given to lower the blood pressure. The individual is also instructed on ways to reduce the risk for rupture such as cessation of smoking.
