Systematic review and cost-effectiveness analysis of elective endovascular repair compared to open surgical repair of abdominal aortic aneurysms

The choice of which option to use depends on the health of the patient, their ability to undergo surgery, whether the patient is symptomatic and the size, progression rate and morphology of the aneurysm. [...] The purpose of the evaluation was to review the evidence concerning the effectiveness and cost-effectiveness of EVAR in comparison to OSR. [...] The primary conclusions of the report was that EVAR should be considered as an adjunctive technology to OSR, that no definitive conclusion could be made about the long-term effectiveness of EVAR due to the poor quality of the available evidence and that EVAR may be appropriate for treating a subset of patients with AAA who are unfit for OSR. [...] The report acknowledged the potential of EVAR but stated that the long-term effectiveness and cost effectiveness could not be determined at the time and that further evaluation of the technology was required. [...] Report Purpose The purpose of this report is to present the results of our systematic literature review and an interim analysis to OHTAC to estimate the cost-effectiveness of EVAR versus OSR based 1) on an updated review of the literature, 2) a preliminary analysis of a subset of patients with 1 year follow-up recruited into the LHSC study and 3) a decision analytic model developed to evaluate the
