A cerebral aneurysm is a weak spot on an artery in the brain that balloons or bulges out and fills with blood. The bulging aneurysm can put pressure on the nerves or brain tissue. It may also burst or rupture, spilling blood into the surrounding tissue (called a hemorrhage).
Most cerebral aneurysms do not show symptoms until they either become very large or rupture causing hemorrhage.
A larger aneurysm that is steadily growing may press on tissues and nerves causing:
When an aneurysm ruptures , patient always experiences a sudden and extremely severe headache (e.g., the worst headache of one's life) and may also develop:
Sometimes an aneurysm may leak a small amount of blood into the brain (called a sentinel bleed). Sentinel or warning headaches may result from an aneurysm that suffers a tiny leak, days or weeks prior to a significant rupture. However, only a minority of individuals have a sentinel headache prior to rupture.
If you experience a sudden, severe headache, especially when it is combined with any other symptoms, you should seek immediate medical attention.
Most cerebral aneurysms go unnoticed until they rupture or are detected during medical imaging tests for another condition.
Usually patient will undergo diagnostic tests like to know the exact characteristics of aneurysm
It will be decide a variety of factors when determining the best option for treating an aneurysm, including:
There are a few surgical options available for treating cerebral aneurysms. These procedures carry some risk such as possible damage to other blood vessels, the potential for aneurysm recurrence and rebleeding, and a risk of stroke.
