Currently available conduits for in situ reconstruction after excision of infected aortic grafts have significant limitations. The Omniflow II vascular prosthesis is a biosynthetic graft associated with a low incidence of infection that has succesfully been used in the treatment of infected infrainguinal bypass. We report on the first use of the Omniflow II prosthesis for in situ reconstruction after aortic graft infection.

A bifurcated biosynthetic bypass was created by spatulating and anastomosing two 8-mm tubular Omniflow II grafts. This bypass was used for in situ reconstruction after excision of infected aortic grafts in three cases. After a mean follow-up of 2.2 years, no occlusion, degeneration, or rupture of the Omniflow II grafts was observed. Although one patient suffered from graft reinfection, the bypass retained structural integrity and no anastomotic dehiscence was observed.

Treatment of aortic graft infection by in situ reconstruction with the Omniflow II vascular prosthesis is feasible. Its resistance to infection and off-the-shelf availability make this graft a promising conduit for aortoiliac reconstruction.
