In disease surveillance, a tension exists between adequate detection of disease progression and the risk for overdiagnosis and unnecessary use of resources. The goal of imaging surveillance after endovascular aneurysm repair (EVAR) can be stated simply: early detection of asymptomatic problems to avoid potentially severe consequences (ie, post-EVAR aneurysm rupture). Existing guidelines for surveillance after EVAR1 are based largely on expert opinion, and high-quality evidence to inform the ideal post-EVAR surveillance regimen does not exist.
