[Surgery in combined aorto-iliac and femoro-popliteal occlusive lesions (author's transl)].

In combined chronic occlusive lesions at the aorto-iliac and femoro-popliteal level the partial repair of the central vessel in combination with profundaplasty and lumbar sympathectomy ("triad procedure") represents a simpler and shorter procedure than the previously preferred total correction of both segments. In a retrospective study of 403 limbs (stage II-IV) the triad procedure shows a cumulative patency (life table analysis) of 77% vs. 39% in total repair. The amputation rate in triad procedure--for stage III/IV--was 8% vs. 36% and the frequency of reoperation 7% vs. 23% in total repair. Prerequisites for this type of repair are an optimal technique and a correct selection of patients presenting patient "receiving segment" of the popliteal artery and a sufficient run-off below the knee.
