Infrarenal aortic aneurysms: New technologies

Nearly two decades after the first successful endovascular aortic repair (EVAR), steady advancements in device technology, deployment techniques, and imaging capabilities have allowed this treatment modality to replace traditional open aortic repair as the treatment of choice for patients undergoing elective abdominal aortic aneurysm (AAA) repair. EVAR now accounts for greater than half of all AAA repairs; however, certain challenges to EVAR remain including anatomic limitations and graft durability. These limitations are now being addressed with new technology and deployment modalities. Surveillance and surgical repair remain the primary focus of therapy for AAA, and this chapter aims to discuss developments in disease surveillance, interventional techniques, and the evolution of endograft devices for EVAR.
