title: Femoro-popliteal versus femoro-distal bypass grafting for limb salvage in patients with an "isolated" popliteal segment.
abstract: In a prospective, multicentre trial, 59 patients with an ischaemic limb and an "isolated" popliteal segment on angiography were randomised to undergo infrainguinal bypass grafting to either the popliteal segment or to a reconstituted distal vessel lower in the calf. Limb salvage was attained with 88% of the femoro-popliteal grafts and 80% of the femoro-distal grafts. There was no difference in the one year graft patency rate between the femoro-popliteal group (79%) and the femoro-distal group (70%). Mean postoperative increase in ankle/brachial pressure index was similar in the two groups despite the presence of occluded or significantly diseased vessels distal to the popliteal anastomoses. Technical difficulties were encountered in 8% of the popliteal group and 24% of the distal group. Femoro-distal bypass grafting confers no apparent benefit over femoral bypass grafting into a patent popliteal segment, even though the popliteal run-off is impaired or occluded.
