High proportion of known abdominal aortic aneurysm in patients with rupture indicates surveillance deficiency

One-third of patients admitted with a rAAA had a previously detected AAA. The surgeons' decision to deny elective surgery and surveillance deficiency were the two main reasons for nontreatment at time of the AAA diagnosis. Improved patient-specific protocols to reduce the surveillance gaps and new methods of determining rupture risk in each case of AAA could be two possible future strategies to reduce the incidence of rupture.
