Ovine Biosynthetic Grafts for Aortoiliac Reconstructions in Nonsterile Operative Fields.

Abstract

BACKGROUND\n\u2003Prosthetic vascular grafts placed surgically or via endovascular techniques can be subject to the risk of life-threatening graft infections. The Omniflow II vascular prosthesis is a biosynthetic graft that was reported to have favorable properties in resisting infections.\n\n\nMATERIALS AND METHODS\n\u2003We retrospectively reviewed our 3 years experience of using the Omniflow II prostheses for aortoiliac reconstructions in patients considered to carry a substantial risk of subsequent prosthetic graft infections (prevention group) as well as in patients with actively infected prosthetic vascular grafts (treatment group).\n\n\nRESULTS\n\u2003Aorto-bi-iliac (n\u2009=\u20094) and aortobifemoral (n\u2009=\u200912) vascular reconstructions were performed using bifurcated Omniflow II prostheses in nine patients in the prevention group and seven patients in the treatment group. During mean follow-up of 28.6\u2009±\u200917.2 months, there was one case of graft infection (6.3%) and graft thrombosis (6.3%) with subsequent successful thrombectomy. Early and late surgical revisions were required in eight (50%) and two (12.6%) patients, respectively. All graft prostheses were patent at last follow-up.\n\n\nCONCLUSION\n\u2003Using bifurcated Omniflow II vascular prostheses in patients with or at a high risk of vascular graft infection is advisable, and is associated with acceptable reinfection and patency rates.
