    What Is a Brain Aneurysm?
    A brain aneurysm is a "bubble" that forms in an artery in the brain; if the artery ruptures, it can be life-threatening. Watch Christopher Koebbe, MD, neurosurgeon at Largo Medical Center, explain.

  • What Are Brain Aneurysms?
    Brain aneurysms are bulging, weakened spots in a blood vessel that can rupture, says Michael Seiff, MD, a neurosurgeon at Sunrise Hospital. In this video, he says that one in 50 people has aneurysms, but many do not rupture.

    A brain aneurysm is an out pouching in a weak spot of an artery of the brain. Most brain aneurysms are asymptomatic. 

    If a brain aneurysm ruptures, it causes bleeding inside the head that can be potentially fatal. The most common symptom of a ruptured aneurysm is severe headache and it should be attended emergently. The larger the aneurysms are, the higher the chance of rupture. 

    Aneurysms can be diagnosed with CTA, MRI/A, and more specifically with femoral cerebral angiogram. Brain aneurysms can be treated by endovascular coil embolization or craniotomy and clip ligation.

    A brain aneurysm is a bleb, or a small bulging, of the blood vessel wall, says Phaniraj Iyengar, MD, a vascular neurologist at Sunrise Hospital. In this video, he describes how dangerous brain aneurysms are if they rupture, and how they are treated.

    A brain aneurysm (also called a cerebral aneurysm) is a blister-like bulge in a weak part of a blood vessel in the brain. It can go unnoticed for a long time. In fact, 1% to 6% of Americans have an aneurysm they don't know about. If left untreated, however, the pressure of the blood causes that area of the wall of the blood vessel to become even weaker, which allows the aneurysm to grow. Eventually the aneurysm may burst, which causes a stroke.
