Study details
- Retrospective, non-randomized, single-center study
- Vein cuffs were created at the distal anastomosis in five patients; no patches were used
- The 3- and 4-year secondary patency rates for below-knee fem-pop and infrapopliteal bypasses were 83% and 72%, respectively
- The 5-year limb salvage rate was 84%
The primary patency results are especially encouraging in light of the fact that the patients were seriously ill, as indicated by the high rates of Rutherford category 4 to 6 disease, renal insufficiency, and previous treatment for PAD and the low rate of multiple-vessel runoff in the series. — Lösel-Sadée
