Abdominal aortic aneurysm refers to a critical disease condition caused in the lower aortic area. Typically enlargement of this major aortic segment is observed in such condition. Due to the importance of this aorta as a premier source of blood supply medium any rupture can become life threatening. At each step the treatment contains medication and proper monitoring of the situation and surgery is generally delayed till the condition becomes worst for the patient or any life risk circumstances arises. Emergency surgery in this regard always remains chancy.
Abdominal aortic aneurysm (AAA) is rare in people aged less than 50 years, but prevalence then rises sharply with increasing age. Abdominal aortic aneurysm affects approximately 4–7% of men and 1–2% of women over the age of 65 years.2–5 Established risk factors for AAA include advancing age, male gender, smoking and family history.
RAAA surgical mortality calculations for RAAA, based on a vascular registry, underestimate the true rate because some cases with fatal outcome tend to escape registration. Because surgical mortality rates may also be skewed by patient selection, total hospital RAAA mortality thus represents the results of RAAA treatment more accurately.
