What are the treatment options for a brain aneurysm?

Brain aneurysms don't always need to be treated. But it is sometimes a good idea to close them off using a or surgery, to prevent them from rupturing (bursting) at some point.
Whether and how a brain aneurysm should be treated depends on the individual case. People without symptoms who have a low risk of complications don’t necessarily need treatment. But it is recommended that you see a doctor for a check-up every one to three years.
To minimize the risk of rupture, it also helps to
- lower your blood pressure if it's too high – for example by changing your diet in order to lose weight, by getting regular exercise, or taking medication,
- not smoke, and
- drink only a little alcohol, or none at all.
These recommendations apply to anyone who has an aneurysm – regardless of whether the risk of complications like bleeding in the brain is high or low.
If the risk of the aneurysm bursting is high, treatment is usually recommended. Various surgical or catheter-based procedures can be used to close off the aneurysm. The choice of treatment depends on different factors – like the position, shape, and size of the aneurysm and the age and general health of the person.
