Aneurysm - cerebral; Cerebral aneurysm
Two common methods are used to repair an aneurysm:
If an aneurysm in the brain ruptures, it is an emergency that needs medical treatment and often requires surgery. Endovascular repair is more often used when this happens.
Even if there are no symptoms, your doctor may order treatment to prevent a future, 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 it is safer to have surgery to block off the aneurysm before it can break open (rupture).
Someone may be too ill to have surgery, or it may be too dangerous to treat the aneurysm because of its location.
Treatment may involve:
Once the aneurysm is repaired, prevention of stroke from blood vessel spasm may be necessary. This may include intravenous fluids, certain medications, and letting the blood pressure get high.
The outcome varies. Patients who are in deep comas after an aneurysm rupture generally do not do as well as those with less severe symptoms.
Ruptured cerebral aneurysms are often deadly. About 25% of people die within 1 day, and another 25% die within about 3 months. Of those who survive, about 25% will have some sort of permanent disability.
Go to the emergency room or call the local emergency number (such as 911) if you have a sudden or severe headache, especially if you also have nausea, vomiting, seizures, or any other neurological symptoms.
Also call if you have a headache that is unusual for you, especially if it is severe or your worst headache ever.
