Contemporary Experience of the Neo-Aortoiliac System (NAIS) Procedure: A Case Series with Review of the Literature.

Objectives: Aortic graft infection (AGI) is a life-threatening complication that can result in death, amputation, sepsis, aorto-enteric fistula, and pseudoaneurysm formation. After explantation of the infected graft, options for reconstruction include extra-anatomic bypass or in-line reconstruction using antibiotic-coated prosthetic graft, cryopreserved allograft, or a neo-aortoiliac system (NAIS) using autogenous femoral veins. While the NAIS procedure has shown promising results, there is relatively limited clinical experience due the magnitude and morbidity of the surgery.
