Abstract

The field of vascular surgery entered an era of change with the introduction of stent graft for the repair of the abdominal aortic aneurysm (AAA). The first reported case by Dr. Parodi in 1991 sparked an interest in minimal invasive, catheter-driven therapeutic intervention of high-risk patients [1, 2]. The early grafts were physician-made devices employing available stents and vascular graft material. These prototypes were aortic–aortic tube grafts made to treat aneurysms with proximal and distal aortic fixation. The technology limited the number of qualified aortic anatomies suitable for these devices. Nevertheless, these first-generation devices only proved effective in short-term treatment of aneurysms as there was up to a 12% delayed aneurysm rupture within 72 months [3]. This eventually led to the formation of bifurcated devices and modular systems with iliac sealing zones, thus expanding the number of patients that could be treated. Endovascular aortic aneurysm repair (EVAR) did not reach center stage until 1999 when the Food and Drug Administration (FDA) granted approval for two industry-made devices for clinical use (AneuRx and Ancure). These second-generation endografts were designed to improve fixation and sealing leading to the improved outcome of EVAR.
