  • What to Expect

  • Reasons for Procedure

    Endovascular embolization can treat many conditions, including:

    • Brain aneurysm—a weakened blood vessel in the brain that collects blood and can bleed
    • Vascular malformations—abnormal connections between arteries and veins (usually present at birth)
    • Tumors

    The procedure can be used alone or with other treatments. It will not fix damaged areas of the brain, but it can improve quality of life by stopping bleeding or preventing rupture.

  • Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

    • Bleeding
    • Weakness
    • Numbness or tingling
    • Speech disturbances
    • Visual changes
    • Confusion, memory loss
    • Seizures
    • Infection
    • Reaction to the anesthesia or contrast solution
    • Blood clots
    • Ruptured aneurysm during surgery

    Factors that may increase the risk of complications include:

    • Smoking
    • Obesity
    • High blood pressure

    Talk to your doctor about these risk factors.
