Femoral Vein Reconstruction for Aortic Infections.

While rare, abdominal aortic infections remain one of the most technically and emotionally challenging cases that a vascular surgeon may face. Secondary infections of either endovascular, or open aortic reconstructions range from 0.2% to 8%. Primary aortic infections are much more rare. Diagnosis can be elusive, depending upon the virulence of the causative microbes, and extent of the infection. Patients are often brittle, with immunocompromise and malnutrition prevalent in this patient population. The gold standard diagnostic test remains a computed tomographic angiogram. The mainstay of management requires vascular control, and wide debridement of all infected materials and revascularization. Multiple methods exist to reconstruct the vascular supply. The neo-aortoiliac system (NAIS) is attractive as it utilizes the patient's own femoral veins to reconstruct the vascular supply after the infection has been extirpated. The procedure is demanding upon the patient and surgeons alike. Also, the rarity of aortic infections limit experiences the literature to centers of excellence. However, the NAIS resists infection well, leaving the patient without any remaining foreign bodies. No further costs for conduit are incurred. Moreover, multiple experiences show excellent durability. While comparative effectiveness literature remains sparse, we believe the NAIS to be the optimal method of revascularization for select patients. In this article, we will review the use of NAIS for primary and secondary aortic infections. In particular, we will emphasize procedural details to help enable the reader to apply this procedure most effectively to their own patients.
