Los aneurismas degenerativos o arterioscleróticos son los mas frecuentes, la primera causa en el caso de aneurisma aórtico abdominal. Es esta la localización. Cuando un aneurisma aórtico abdominal requiere tratamiento, es posible que el médico recomiende una reparación de aneurisma endovascular (EVAR). An aortic aneurysm is an enlargement (dilation) of the aorta to greater than times normal size. They usually cause no symptoms except when ruptured. Occasionally, there may be abdominal, back, or leg pain. They are most commonly located in the abdominal aorta, but can also be.

Screening for an aortic aneurysm so that it may be detected and treated prior to rupture is the best way to reduce the overall mortality of the disease. The walls of a failing aorta are replaced and strengthened. Decisions about repairing an aortic aneurysm are based on the balance between the risk of aneurysm rupture without treatment versus the risks of the treatment itself.


The diameter of the aneurysm, its rate of growth, the presence or absence of Marfan syndromeEhlers—Danlos syndromes or similar connective tissue disorders, and other co-morbidities are all important factors in the overall treatment. They are most commonly located in the abdominal aortabut can also be located in the thoracic aorta. From Wikipedia, the free encyclopedia. First, there is consideration of the risk of problems occurring during and immediately after the procedure itself “peri-procedural” complications.

Screening with ultrasound is indicated in those at high risk, prevention is by decreasing risk factors such as smoking, and treatment is either by open or endovascular surgery.

Rupture risk is also related to shape; so-called “fusiform” long aneurysms are considered less rupture prone than “saccular” shorter, bulbous aneurysms, the latter having more wall tension in a particular location in the aneurysm wall.
