An abdominal aortic aneurysm, also called aaa or triple a, is a bulging, weakened area in the wall of the aorta (the largest artery in the body) resulting in an abnormal widening or ballooning greater than 50 percent of the normal diameter (width). viagra online The aorta is under constant pressure as blood is ejected from the heart. With each heart beat, the walls of the aorta distend (expand) and then recoil (spring back), exerting continual pressure or stress on the already weakened aneurysm wall. Therefore, there is a potential for rupture (bursting) or dissection (separation of the layers of the aortic wall) of the aorta.    this may cause life-threatening hemorrhage (uncontrolled bleeding). viagra xanax mix The larger the aneurysm becomes, the greater the risk of rupture. buy viagra online without script   sometimes, a tear can occur on the inside layer of the vessel resulting in blood filling in between the layers of the blood vessel wall and creating a dissection.   because an aneurysm may continue to increase in size, along with progressive weakening of the artery wall, surgical intervention may be needed. Preventing rupture of an aneurysm is one of the goals of therapy.   what causes an abdominal aortic aneurysm to form? An abdominal aortic aneurysm may be caused by multiple factors that result in the breaking down of the well-organized structural components (proteins) of the aortic wall that provide support and stabilize the wall. The exact cause is not fully known. Atherosclerosis (a build-up of plaque, which is a deposit of fatty substances, cholesterol, cellular waste products, calcium and fibrin in the inner lining of an artery) is thought to play an important role in aneurysmal disease, including the risk factors associated with atherosclerosis. They include: age (greater than 60) male (occurrence in males is four to five times greater than that of females) family history (first degree relatives, such as father or brother) genetic factors hyperlipidemia (elevated fats in the blood) hy. viagra for sale viagra for sale uk
