  • United Hospital offers exceptional care for patients with brain aneurysms and vascular malformations. United's comprehensive team of specialist physicians is led by Eric Nussbaum, MD, a neurosurgeon who specializes in aneurysm surgery. Dr. Nussbaum's patients have far lower complication rates than the national average for this type of surgery.

  • Symptoms

    Brain aneurysms usually have no symptoms until they bleed. Symptoms of a ruptured aneurysm may include:

    • Severe, sudden headache, described as "the worst headache of my life"
    • Neck stiffness
    • Sensitivity to light
    • Nausea and vomiting
    • Loss of consciousness
    • Seizures

    Most people with brain aneurysms realize that something is wrong and go to a hospital emergency room.

    Why aneurysms are dangerous

    Aneurysms that bleed are very serious: half of patients die before reaching a hospital or within the first few days. Of the patients who survive a ruptured aneurysm, half develop a serious disability.

    A ruptured brain aneurysm requires treatment because it is likely to bleed again. Each time a brain aneurysm bleeds, the risk of death or disability is high.

  • Common problems

    The possibility of these medical problems reinforces the need for prompt treatment after a ruptured aneurysm.

  • Vascular malformations

    Specialists in brain aneurysms at United Hospital also care for patients with vascular malformations.

    Vascular malformations are abnormal connections between the arteries and veins in the brain. They are also called arteriovenous malformations (AVMs). These usually form before birth.

    AVMs are located within the brain. Without the normal channels of vessels to handle blood under high pressure, AVMs can bleed. The bleeding causes a blood clot in the brain, which can lead to death or disability.

    Although not as dangerous or common as brain aneurysms, AVMs have significant risks.
