Endovascular aneurysm sealing (EVAS) is a disruptive technology to treat abdominal
aortic aneurysm (AAA). The use of sac filling rather than endograft fixation was designed
to treat aortic aneurysms in a wide range of morphologic appearances and to reduce
endoleaks. There are few data reporting outcomes beyond postoperative follow-up. This
study reports outcomes up to 5 years for Nellix (Endologix, Irvine, Calif) EVAS.
