Short Description or Definition
An aneurysm is an abnormal blood-filled dilatation of a blood vessel that can occur in vascular innervated areas (Webster 2006). Cerebral aneurysms are generally located at arterial curvatures and bifurcations that are exposed to major hemodynamic forces (Kulcsár et al. 2011). Aneurysms generally develop due to trauma, infections, congenital defects, or degenerative diseases (Parkin and Leng 1993). Blood from a ruptured brain aneurysm can leak into the brain (i.e., hemorrhagic stroke). If blood leaks into the space between the brain and the thin tissues covering the brain, this type of hemorrhagic stroke is classified as a subarachnoid hemorrhage (Mayo Clinic Staff 2015). An aneurysm can also dissect, which is a split in one or more layers of the artery wall that causes bleeding into and along the layers of the artery wall (NIH 2011). The size and rate of growth of an unruptured cerebral aneurysm will affect signs and...
