  1. The cost-effectiveness of endovascular repair versus open surgical repair of abdominal aortic aneurysms : A decision analysis model. Discussion.

    Article, Communication - En anglais

    Annual Meeting of the New England Society for Vascular Surgery. Toronto, ON, CAN, 1998/09/24.


    Endovascular repair (EVR) is a less-invasive method for the treatment of abdominal aortic aneurysms (AAAs) as compared with open surgical repair (OSR).

    The potential benefits of EVR include increased patient acceptance, less resource utilization, and cost savings.

    This study was designed to determine whether the EVR of AAAs is a cost-effective alternative to OSR.


    A cost-effectiveness analysis was performed using a Markov decision analysis model to compute long-term survival rates in quality-adjusted life years and lifetime costs for a hypothetical cohort of patients who underwent either OSR or EVR.

    Probability estimates of the different outcomes of the two alternative strategies were made on the basis of a review of the literature.

    The average costs of (1) the immediate hospitalization ($16,016 for OSR, $20,083 for EVR), (2) the complications that resulted from each procedure, (3) the subsequent interventions, and (4) the surveillance protocol were determined on the basis of average resource utilization as reported in the literature and from our hospital's cost accounting system.

    Our measure of outcome was the cost-effectiveness ratio. (...)
