Brain Aneurysm

About brain aneu​rysms

A brain aneurysm is a bulge in the wall of a brain artery. If this bulge tears and bleeds, nearby cells may be damaged. A brain aneurysm can occur in an artery wall that is weak or has a defect.

Risk factors for brain aneurysms include:

  • High blood pressure
  • Heredity
  • Smoking
  • Acohol abuse
  • Cocaine abuse
  • Head injury

Brain aneurysm treatment options


A brain aneurysm needs to be evaluated immediately and treated if possible. If the aneurysm has bled, treatment may not reverse the resulting brain damage. But, in many cases, surgery may help prevent more bleeding, remove trapped blood in and around the brain or relieve excessive brain pressure.

Treatment plans for patients will be determined by their care team based on age, medical history, type and stage of brain aneurysm and personal preferences. ​
