Prospective evaluation of an interactive model for endovascular aortic aneurysm repair (EVAR) developed to allow clinicians to preoperatively predcit the likelihood of individual failure based on perioperative & aneurysm-related mortality, need for reintervention, type I and II endoleaks and 3 year survival.

This trial has updated a risk assessment model which helped inform patients of possible outcomes and complications before they undergo endovascular aneurysm repair (EVAR). The results from the current trial have allowed the development of a new easy-to-use predictive model. Ten preoperative clinical and anatomical factors are entered into the software which then calculates the percentage likelihood of complications after surgery. This knowledge can be used for discussion between the patient and the surgeon at the preoperative consultation to assist in shared-decision making between the patient and surgeon. Of particular note is the finding that self-reported fitness contributes significantly to outcomes after EVAR surgery, with fit patients having a much lower risk of early or late death after EVAR.
