Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Device Technology

Background:

  • Endovascular treatment of peripheral arterial disease (PAD) has expanded significantly.
  • Atherectomy technologies aim to mitigate complications associated with traditional angioplasty, such as dissection and elastic recoil.

Purpose of the Study:

  • To review various atherectomy devices used in endovascular PAD treatment.
  • To discuss the indications, advantages, and limitations of different atherectomy technologies.

Main Methods:

  • Review of established and emerging atherectomy technologies: excimer laser, Rotablator, Diamondback, Silverhawk, Rockhawk, and Jetstream.
  • Analysis of device mechanisms, including photoablation, rotational sanding, directional cutting, and aspiration.
  • Examination of specific applications for different lesion types (calcified, eccentric) and anatomical locations (popliteal, infrapopliteal).

Percutaneous Endoscopic Unilateral-Approach Bilateral Decompression for Lumbar Spinal Stenosis

Published on: February 9, 2024

Main Results:

  • Excimer laser uses photoablation; Rotablator and Diamondback are rotational devices for calcified plaques.
  • Silverhawk is directional for eccentric lesions; Rockhawk targets calcified plaques.
  • Jetstream is a rotational device with aspiration capability for native arteries.

Conclusions:

  • Atherectomy offers diverse options for PAD treatment, each with specific strengths and weaknesses.
  • Device selection should be based on lesion characteristics and anatomical site.
  • Emerging technologies like Jetstream integrate multiple functionalities, potentially improving treatment outcomes.
