title: [The PTFE plastic prosthesis as an arterial replacement: experiences over a 5-year period].
abstract: Unilateral iliac femoral reconstructions with PTFE are yielding good results-similar to those with Dacron, with patency rates of 75, 67, and 65% at 1, 2 and 3 years, respectively (Kaplan-Meier). PTFE has additional advantages compared with other materials: a) no need of preclotting; b) smooth inner surface-easy thrombectomy in case of thrombosis and c) good handling characteristics. In view of the above-mentioned facts PTFE can be recommended without restriction for unilateral pelvic reconstructions. The functional early results of bilateral aorto-femoral Goretex-Y bifurcation grafts in 50 cases after 2 years are encouraging. Long-term results are still pending. Reports of other groups using this material as aorto-bifemoral substitute are not yet available. The functional results with PTFE for femoro-popliteal grafts are not satisfactory: 35% after 2.5 years. Extra-anatomical bypasses yielded 70% one-year functioning rate. Especially the ring-or spiral-armoured PTFE grafts seem to be suitable for these reconstruction procedures.
