 Abdominal aneurysms are usually asymptomatic but in rare cases can cause lower back pain or lower limb ischemia.Risk factors for an aneurysm include diabetes, obesity, hypertension, tobacco use, alcoholism, high cholesterol, copper deficiency, increasing age, and tertiary syphilis infection.Connective tissue disorders such as Loeys-Dietz Syndrome, Marfan Syndrome, and certain forms of Ehlers-Danlos Syndrome are also associated with aneurysms.
