Cerebral aneurysm


Overview: The phrase cerebral aneurysm refers to the bulging of a weakened area in the wall of an artery in the brain, resulting in abnormal ballooning. Because there is a weakened spot in the aneurysm wall, there is a risk for rupture (bursting) of the aneurysm. A cerebral aneurysm more frequently occurs in an artery located in the front part of the brain that supplies oxygen-rich blood to the brain tissue. Arteries anywhere in the brain can develop aneurysms. The most common type of cerebral aneurysm is called a saccular, or berry, aneurysm, so named because the deformity looks like a “berry” with a narrow stem. Fusiform and dissecting are the other two types of aneurysm—the former bulges out on all sides forming a dilated artery and are often associated with atherosclerosis. A dissecting aneurysm results from a tear along the length of the artery in the inner layer of the artery wall, causing blood to leak in between the layers of the wall. This may cause a ballooning out on one side of the artery wall, or it may block off or obstruct blood flow through the artery. Dissecting aneurysms usually occur from traumatic injury, but they can also happen spontaneously. The shape and location of the aneurysm may determine which treatment is recommended. Smaller aneurysms may have a lower risk of rupture.
