Cerebral Aneurysm

The word aneurysm comes from the latin word aneurysma, which means dilation. An aneurysm is an abnormal local dilation in the wall of a blood vessel, usually an artery. It can be caused by a defect, a disease, or an injury. A cerebral aneurysm is an abnormal focal dilation of an artery located in the brain that results from a weakening of the inner muscular layer called the intima of a blood vessel wall (Brisman, 2014). The vessel develops a blister-like dilation that becomes thin and may rupture without warning. The rupture causes bleeding into the space around the brain which produces a subarachnoid hemorrhage (SAH). This kind of hemorrhage can lead to a stroke, coma , and/or death (Singla & Hoh, 2015).

It is the junction of two carotid arteries and two vertebral arteries. This junction, where the arteries all come together, has a high possibility of forming weak spots that become more prone to fill up with blood and balloon out forming a sac-shaped aneurysm (Wedro, 2016). Smaller arteries branch out from this center and supply oxygenated blood to 80% of the cerebrum (Kantor, 2015).
Cerebral aneurysms are all different. They vary in shape, size, and location. Cerebral aneurysms are classified into three basic types based on their shape. These types are saccular, lateral, and fusiform (Zuccarello, 2016). Saccular aneurysms account for 90% of all aneurysm shape types (Buckley, 2016). This type forms a sac outside the artery that looks like a berry, therefore commonly referred to as a “berry aneurysm” (Brisman, 2014). It is attached by a neck of stem to an artery or a branch of a blood vessel. It is usually located on arteries at the base of the brain. A lateral aneurysm appears as a bulge on one …show more content…

Aneurysms can be present in anybody at any age (Koroshetz, 2015). They usually do not exhibit any symptoms or dangers if unruptured. The following risk factors however may increase your risk for a ruptured cerebral aneurysm. They are age, family history, previous aneurysm, gender, race, high blood pressure, smoking, and drug and alcohol abuse (Koroshetz, 2015). Cerebral aneurysms are rarely developed in infants and children. Manifestation increases directly with age eventually reaching its peak among those between the ages of 55-60 (Liebeskind, 2015). Women are more likely to develop a brain aneurysms or to suffer a subarachnoid hemorrhage than men. African Americans are more prone than whites to suffer from subarachnoid hemorrhage. Those with high blood pressure or habits of smoking also increase their chances of a brain aneurysm rupturing. That being stated, not all aneurysms will rupture. An estimated 50 to 80 percent of all aneurysms never rupture in a person’s lifetime (Liebeskind, 2015). The true danger with a cerebral aneurysm is the possibility of it rupturing and bleeding into the brain. This bleeding can lead to a hemorrhagic stroke, permanent nerve damage, or death. Once an aneurysm bursts it can rerupture and continue bleeding into the brain while forming additional aneurysms. Bleeding into the brain lasts only a few seconds, but if can cause very severe complications. Commonly the
