[Technical innovations in femoro-tibial reconstructions].

The literature on reconstructive femoro-tibial surgery includes distal by-pass implantation, personally considered the most interesting and most debated part. Four cases treated with double femoro-popliteal and popliteo-tibial reconstruction, three with the jump-by-pass technique and one with the sequential-by-pass technique are reported. Of these cases, three are complete with fluximetric and angiographic examination before, during and after the operation. Final results are considered satisfactory, notwithstanding certain inconveniences which were dealt with as they arose. Long-term follow-up permits some optimism for the future of this surgery, although the technical difficulties are by no means negligible.
