Crossover femoral-popliteal and femoral-tibial bypass.

Crossover femoral-popliteal or femoral-tibial bypass has been employed as an alternative extra-anatomic bypass in 3 patients who had occlusion of an iliac artery with subsequent occlusion of the ipsilateral femoral artery with patency of either a popliteal or tibial artery and a patency of the contralateral common femoral artery. Each patient had a contraindication to a more conventional type of procedure. All procedures were performed with reinforced PTFE grafts. All grafts have remained patent for 6 months to 3 years. This operation should be considered as an alternative extra-anatomic reconstructive procedure in patients with the appropriate anatomy and who are not candidates for more standard types of vascular reconstruction.
