Should Usual Criteria for Intervention in Abdominal Aortic Aneurysms Be “Downsized,” Considering Reported Risk Reduction with Endovascular Repair?

: Two randomized trials have demonstrated the safety of waiting until abdominal aortic aneurysm (AAA) diameter reaches 5.5 cm for repair in most patients. Other recent randomized trials have demonstrated lower perioperative mortality and morbidity with endovascular aneurysm repair (EVAR) compared to open surgery. Therefore, it is logical to assume that endovascular repair may change the appropriate threshold for intervention. However,...
