Comparison of Angioplasty/Drug Coated Balloon/Laser + Drug Coated Balloon for Femoropopliteal Artery In-stent Restenosis

The publication show that there is probably an effectiveness gradient (expressed as a proportion of patients with in-stent restenosis a 18 months after the intervention of the first stenosis reduction): standard balloons would be less effective than active balloons themselves less effective than in combination with the excimer laser. Reducing the risk of In-Stent Restenosis has major implications for the treatment of patients because it reduces the use of arterial bypass or amputation, if unable to perform revascularization.

Based on these promising results of efficiency, we can hypothesize that the active balloons in combination with the Excimer laser would improve the quality of life of patients while reducing the cost of their treatment, this compared to only assets balloons. This same improvement in quality of life with reduced costs of care would be observed for only assets compared to standard balloons. In health economic terms, it is therefore likely that the strategy combining assets balloons and Excimer laser is dominant over assets balloons themselves dominant over standard balloons.
