Autologous alternative veins may not provide better outcomes than prosthetic conduits for below-knee bypass when great saphenous vein is unavailable

“…Previous studies of infrageniculate bypass have shown conflicting outcomes when prosthetic grafts are compared with AACs. 8,15,16 In contrast to our study, Kreienberg et al 16 showed secondary patency was significantly better for composite vein conduits compared with prosthetic grafts in a small prospective randomized study. It should also be noted that a recent study comparing GSV, AAC, and NAC showed that AACs carried no advantage over prosthetic bypasses to infrageniculate targets in primary assisted patency, secondary patency, and limb salvage at 2 years of follow-up, which is consistent with the findings in our study.…”

“…Other studies have monitored participants for a greater duration. 15 We also note that we could not perform a subgroup analysis among NAC and AAC groups. NAC, for example, is composed of >80% PTFE, 2% Dacron (DuPont, Wilmington, Del), and 16.4% nonautologous biologic veins.…”

“…Aihara et al reported been previously reported. 13, 14 In the present study, one-third of tibial artery bypasses with a vein graft cases were performed using a spliced vein graft, which greatly decreased the patency rate of the vein graft. The percentage of composite grafts with a vein in the report of Conte et al was 2.7%, 6 and Byrne et al 5 reported that 70% in-situ vein grafts and 30% excised vein grafts were used in their study.…”

“…Finally, Avgerinos et al. [ 18 ] reported on the retrospective analysis of a collective comprising a total of 407 infrainguinal bypasses including 116 popliteal (29 %), 226 tibial (56 %) and 65 pedal (16 %). Of these bypasses 96 % were in CLI patients whereby GSV grafts were performed in 63 % ( n = 255), alternative autologous vein grafts (upper extremity veins and composite vein segments) in 26 % (106) and prosthetic grafts in 11 % ( n = 47), of which 41 were heparin-bonded PTFE grafts.…”
