Retrospective data were obtained on all patients with a diagnosis of RAAA using the Australian and New Zealand Intensive Care Society database as recorded using STATIC software and the patient's medical records.
Epidemiological studies on abdominal aortic aneurysms have shown an increasing incidence of RAAA (6-8).
Several factors were found to be associated with an increased mortality following RAAA.
This may imply that presence of COPD in older patients presenting with RAAA may be a factor that increases mortality.
The impact of delay to surgery on survival in patients with RAAA was evaluated in a retrospective study by Salhab et al (18).
The decreased mortality associated with RAAA when surgery is performed by a vascular surgeon is consistent with published data from Massachusetts that reviewed RAAA in five community hospitals over a 12-year period.
