Two common methods are used to repair an aneurysm:
- Clipping is done during open brain surgery (craniotomy).
- Endovascular repair is most often done. It usually involves a coil or coiling. This is a less invasive way to treat some aneurysms.
If an aneurysm in the brain ruptures, it is an emergency that needs medical treatment and often requires surgery. Endovascular repair is often used when this happens.
Even if there are no symptoms, your doctor may order treatment to prevent a future, and possibly fatal rupture.
Not all aneurysms need to be treated right away. Those that are very small (less than 3 mm) are less likely to break open.
Your doctor will help you decide whether or not it is safer to have surgery to block off the aneurysm before it can break open (rupture). Sometimes people are too ill to have surgery, or it may be too dangerous to treat the aneurysm because of its location.
Treatment of a ruptured aneurysm may involve:
- Being admitted to the hospital's intensive care unit (ICU)
- Complete bedrest and activity restrictions
- Drainage of blood from the brain area (cerebral ventricular drainage)
- Drugs to prevent seizures
- Drugs to control headaches and blood pressure
- Drugs through a vein (IV) to prevent infection
Once the aneurysm is repaired, the person may need to prevent a stroke from a blood vessel spasm.
