How I do it: The neoaortoiliac system for treatment of aortoduodenal fistula after endovascular aortic repair

Abstract

The term neoaortoiliac system (NAIS) was coined by Clagett in 1993 to describe the use of the deep veins in the thigh to replace the aorta and iliac arteries in the setting of graft infection. Since that time, the NAIS procedure has been used to treat a wide array of both infectious and noninfectious conditions affecting the aortoiliac segment. In this article, we present a 10-step description of the NAIS procedure to treat an aortoduodenal fistula in a patient with an infected endovascular aneurysm repair.
