Cerebral Aneurysm

A cerebral aneurysm occurs when a weak or thin spot in a blood vessel inside the brain fills with blood and starts to balloon outward. The expanding vessel can create pressure within the brain tissue or on a nerve and may begin to leak or rupture, causing blood to spill into the brain tissue.

A small cerebral aneurysm may not produce any symptoms.  As it expands, symptoms may include headache, numbness in the face and vision problems. A ruptured cerebral aneurysm may cause a sudden, severe headache, nausea, vomiting, vision problems and loss of consciousness.

Early diagnosis is important.  Surgical treatment may include placing a clip on the aneurysm, or inserting a metal coil through a catheter in the groin, similar to the approach for some cardiac procedures, to create a clot at the aneurysm site.
