PRELIMINARY-RESULTS OF A PROSPECTIVE RAND OMIZED STUDY REGARDING FEMOROPOPLITEAL BYPASS MATERIAL

In case of insufficient or missing greater saphenal vein or if the sap henal vein might he of important use for future bypass grafts, the que stion arises which alternative bypass material is the more appropriate choice, A literature review to that topic produced only unsatisfactor y results, In a prospective randomized controlled clinical study (n=25 0 patients) we compare the patency rates of either PTFE or Dacron as b ypass material for femoropopliteal P-I-Bypass in chronic arterial occl usive disease, A preliminary evaluation of n=103 patients (PTFE n=52; Dacron n=51) reveals an operative and immediate mortality rate of 0% a nd a loss of limb rate of 3.9% (PTFE) and 3.8% (Dacron), The secondary cumulative patency rate after 540 days of observation is 79.6% (PTFE) and 87.1% (Dacron), We so far find no statistically significant diffe rence between both graft materials.
