Variations in the utilization of endovascular aneurysm repair reflect population risk factors and disease prevalence

While there was substantial regional variation in the use of EVAR, utilization of the less morbid procedure was well correlated with higher risk populations (number of diabetic patients and deaths secondary to heart disease). Contrary to other studies of regional discrepancies in the utilization of some surgical procedures, it appears that the utilization of EVAR was not associated with physician distribution, socioeconomics, or other non-medical factors.
