Cerebral aneurysm

Alternative names:

aneurysm - cerebral

Treatment:

Because symptoms often do not appear until bleeding occurs, cerebral aneurysm may be an emergency condition when it is discovered. The goal of treatment is to control symptoms and prevent further bleeding. Surgery is the primary treatment for cerebral aneurysm. The base of the aneurysm is closed off with clamps, sutures, or other methods that prevent blood flow through the aneurysm.

If surgery is not feasible because of the location or size of the aneurysm or the condition of the person, medical treatment is similar to treatment for subarachnoid hemorrhage. This may include restricting activity (often complete bedrest is advised), treating symptoms such as headache, and prescribing preventive (prophylactic) use of antiseizure medications.

Expectations (prognosis):

The outcome varies. A cerebral aneurysm that does not rupture may not cause any symptoms. However, about 25% of ruptured cerebral aneurysms are fatal within 24 hours. Another 25% are fatal within about 3 months. Of the remaining people with ruptured cerebral aneurysm, more than one-half will have some sort of permanent disability.

Complications:

• subarachnoid hemorrhage
• stroke
• epilepsy
• paralysis of any part of the body
• permanent loss of sensation of any part of the body
• other neurologic deficits (such as vision changes, loss of speech ability)
• communicating hydrocephalus

Calling your health care provider:

Go to the emergency room or call the local emergency number (such as 911) if sudden or severe headache occurs, particularly if accompanied by vomiting, seizures, or other symptoms of cerebral aneurysm.
