Nonruptured Cerebral Aneurysm


A cerebral aneurysm is a bulging or weak area in an artery that brings blood to your brain. The area fills with blood and expands. The aneurysm can expand so much that blood bursts through the artery. This is a hemorrhagic stroke. An aneurysm that has not burst can be managed or treated to prevent it from rupturing. An aneurysm can happen anywhere in your brain. They most commonly form between the brain and the base of the skull.


Call 911 for any of the following:

  • You have any of the following signs of a stroke:
    • Numbness or drooping on one side of your face
    • Weakness in an arm or leg
    • Confusion or difficulty speaking
    • Dizziness, a severe headache, or vision loss
  • You lose consciousness or have a seizure.

Seek care immediately if:

  • You have a stiff neck or trouble walking.
  • You have nausea or are vomiting.
  • You have blurred or double vision, or you are sensitive to light.
  • You suddenly feel weak.

Contact your healthcare provider if:

  • You have questions or concerns about your condition or care.

Follow up with your healthcare provider as directed:

You may need ongoing tests to check the size and condition of the aneurysm over time. Write down your questions so you remember to ask them during your visits.

Manage a nonruptured aneurysm:

  • Control high blood pressure. Keep your blood pressure at the level your healthcare provider recommends. If you are a woman, ask your healthcare provider if birth control pills are safe for you. Birth control pills can also increase blood pressure.
  • Do not smoke. Nicotine can damage blood vessels and make it more difficult to manage your blood pressure. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your healthcare provider for information if you currently smoke and need help quitting.
  • Do not drink alcohol or use illegal drugs. Alcohol and illegal drugs such as cocaine can increase your blood pressure. Ask your healthcare provider for information if you need help quitting.
  • Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, beans, lean meats, fish, and low-fat dairy products. Your healthcare provider or dietitian can help you create a meal plan to help control high blood pressure or cholesterol. You may also need to limit sodium (salt).
  • Exercise as directed. Exercise can help control your blood pressure and cholesterol level. Ask your healthcare provider how much exercise you need each day and which exercises are best for you.
