Contemporary results with the biosynthetic glutaraldehyde denatured ovine collagen graft (Omniflow II) in femoropopliteal position.

The OCP provides satisfactory medium- and long-term patency and limb salvage in the femoropopliteal position. Aneurysmal degeneration or graft stenosis may develop over time, demanding lifelong duplex ultrasound surveillance and secondary intervention if needed. Its possible infection-resistant behavior in a contaminated field combined with an acceptable graft patency and limb salvage justifies the use of this graft in the absence of autologous vein.
