These results suggest that DCB are safe and effective in delaying rather than preventing restenosis in long, complex lesions and restenosis of the femoropopliteal tract. Further studies are recommended to confirm these results.

Restenosis-rate after angioplasty of extensive infrapopliteal arterial disease is high and occurs early after treatment. Despite this the clinical results are excellent, especially given the length of the arterial segments diseased.

The early restenosis rate of long-segment infrapopliteal disease is significantly lower after treatment with DEBs compared with historical data using uncoated balloons. Randomized trials are required to show whether this difference will lead to improvement in clinical outcomes.
