Variant Neo-Aortoiliac System Operation Using a Composite Conduit of Silver-Coated Dacron Graft and Autologous Femoral Veins: A Report of Two Cases.

Aortic prosthesis infection is associated with significant morbidity and mortality rates. The introduction of the neo-aortoiliac system (NAIS) technique offers a new perspective, as a venous conduit is considered an optimal graft in aortic prosthesis infection because it is autogenous, durable, inexpensive and has low infection rates. Occasionally, the anatomical characteristics of available autologous venous conduits may limit the applicability of this technique.
