This model was created and internally validated using 4431 VSGNE patients¹ who had elective AAA repair and subsequently validated in external sample of 16,989 VQI sample after excluding the patients from VSGNE sample²

1. COPD is defined as yes or no. Any COPD is considered a risk factor.

2. Cerebrovascular disease is history of prior CEA/CAS

3. This model can be used for both open and endo; for endo risk score starts at zero and for open it starts at 2 if clamp position is planned infra-renal or 4 if clamp is placed supra-renal. Clamps placed above one renal and below another (intra-renal are considered infra-renal clamps)
