The Redha-cut atherectomy device safely and effectively removed plaque in femoro-popliteal lesions, significantly reducing stenosis. This innovative tool shows promise for improving peripheral artery disease treatment.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Device Technology

Background:

  • Femoro-popliteal lesions cause significant morbidity.
  • Percutaneous atherectomy aims to remove atherosclerotic plaque.
  • Novel devices are needed to improve safety and efficacy.

Purpose of the Study:

  • To assess the safety, feasibility, and efficacy of the Redha-cut atherectomy device.
  • To evaluate the Redha-cut device for symptomatic femoro-popliteal lesions.

Main Methods:

  • Prospective study of 70 patients with 93 femoro-popliteal lesions.
  • Percutaneous atherectomy performed using the Redha-cut device.
  • Quantitative angiographic analysis before and after procedure.

Main Results:

  • Successful atherectomy sample retrieval in all cases.
  • Mean stenosis reduced from 74% to 26% (p < 0.001).
  • 6-month and 12-month cumulative patency rates were 83% and 66% respectively.

Conclusions:

  • Redha-cut is a safe, feasible, and effective tool for atherectomy.
  • The device facilitates plaque removal and stenosis reduction.
  • Further comparative studies are planned to evaluate long-term outcomes.
