Abstract:
Abdominal aortic aneurysm (AAA) rupture causes 2% of all deaths among men aged 65 years or more. Since aneurysmectomy is associated with an operative mortality reaching 5%, the risk of rupture determines whether prophylactic surgery should be performed or not. Many studies have been carried out to estimate the risk of rupture, but the results vary greatly. Thus, the rupture risk of an AAA with a diameter of 4.0-4.9 cm ranges from 1% to 23% per year. The most likely rupture rates are assumed to be < 1% per year for AAAs < 4.0 cm, 1-2% per year for AAAs of 4.0-5.0 cm, and at least 10% per year for AAAs > 5.5 cm.
