Treatment for a symptomatic aneurysm is to repair the blood vessels. Clipping and coiling are two treatment options.

• Clipping: A neurosurgeon can operate on the brain by cutting open the skull, identifying the damaged blood vessel and putting a clip across the aneurysm. This prevents blood from entering the aneurysm and causing further growth or blood leakage.
  
  
• Coiling: A neurosurgeon or interventional radiologist can thread a tube through the arteries, as with an angiogram, identify the aneurysm, and fill it with coils of platinum wire or with latex. This prevents further blood from entering the aneurysm and resolves the problem.

Both these options have the risk of damaging the blood vessel and causing more bleeding, damaging nearby brain tissue, and causing the surrounding blood vessels to go into spasm; depriving brain tissue of blood supply and causing a stroke.

Prior, during, and after surgery, attention is paid to protect the brain and its blood vessels from potential further damage. Vitals signs are monitored frequently, and heart monitors are used to watch for abnormal heart rhythms. Medications may be used to prevent blood vessel spasm, seizure, agitation, and pain.

Brain aneurysms are deadly. About 10% of patients with a ruptured aneurysm die before receiving medical care. If untreated, another 50% will die within a month, with 25% of patients sustaining another bleeding episode within a week. Aside from the bleeding issues, there is significant risk of artery spasm leading to stroke.

Survival rates are increased by early presentation to the hospital, early aneurysm repair, and control of potential blood vessel spasm with medications.
