Clinical Information
  • An aneurysm is a bulge or "ballooning" in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death. Most aneurysms occur in the aorta, the main artery traveling from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the brain, heart and other parts of the body. If an aneurysm in the brain bursts, it causes a stroke. Aneurysms can develop and become large before causing any symptoms. Often doctors can stop aneurysms from bursting if they find and treat them early. Medicines and surgery are the two main treatments for aneurysms.
  • Bulging or ballooning in an area of an artery secondary to arterial wall weakening.
  • Pathological outpouching or sac-like dilatation in the wall of any blood vessel (arteries or veins) or the heart (heart aneurysm). It indicates a thin and weakened area in the wall which may later rupture. Aneurysms are classified by location, etiology, or other characteristics.
  • Pathological, blood-filled distension of blood vessel
  • Protruding sac in the wall of a vein, artery, or heart, frequently caused by microbial infection; may present as pain, pressure on nearby organs, or cardiac weakening.
