An aneurysm (AN-u-rism) is a balloon-like bulge in an artery. Arteries are blood vessels that carry oxygen-rich blood to your body. Arteries have thick walls to withstand normal blood pressure.However, certain medical problems, genetic conditions, and trauma can damage or injure artery walls.n aneurysm can grow large and rupture (burst) or dissect. A rupture causes dangerous bleeding inside the body. A dissection is a split in one or more layers of the artery wall. The split causes bleeding into and along the layers of the artery wall. Both rupture and dissection often are fatal.
The word aneurysm comes from the Latin word aneurysma, which means dilatation. Aneurysm is an abnormal local dilatation in the wall of a blood vessel, usually an artery, due to a defect, disease, or injury. Aneurysms can be true or false. A false aneurysm is a cavity lined by blood clot.The 3 major types of true intracranial aneurysms are saccular, fusiform, and dissecting.hown here is a CT scan of an aneurysmal subarachnoid hemorrhage.
