Follow-up costs increase the cost disparity between endovascular and open abdominal aortic aneurysm repair

EVAR results in significantly greater hospital costs compared with OR, despite reduced hospital and intensive care unit stays. The inclusion of follow-up costs further increases the cost disparity between EVAR and OR. Because EVAR requires lifelong surveillance and has a high rate of reintervention, follow-up costs must be included in any cost comparison of EVAR and OR. The economic cost, as well as the efficacy, of new technologies such as EVAR must be addressed before their widespread use is advocated.
