Summary
Retrograde Auth Rotablator atherectomy via pedal artery open approach successfully treated severe infrapopliteal artery disease. This technique improved limb salvage by maintaining arterial patency and preventing complications.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Regenerative Medicine
Background:
- Severe, diffuse atherosclerotic disease of infrapopliteal arteries poses challenges for conventional vascular surgery and balloon angioplasty.
- High-speed rotational atherectomy (Auth Rotablator) has shown limited success due to poor long-term patency and the non-reflow phenomenon.
Observation:
- A case of critical limb ischemia due to long occlusion of three infrapopliteal vessels was managed.
- The anterior tibial artery was treated using a retrograde Auth Rotablator atherectomy approach through an open pedal artery arteriotomy.
Findings:
- The retrograde atherectomy resulted in full patency of the treated anterior tibial artery.
- Skin lesions healed, indicating successful limb salvage.
- Microparticulate debris was effectively drained via the pedal arteriotomy, mitigating complications associated with antegrade atherectomy.
Implications:
- This retrograde approach offers a promising alternative for limb salvage in complex infrapopliteal arterial disease.
- Minimizing debris-related complications may improve outcomes for Auth Rotablator procedures.
- Further research into retrograde atherectomy techniques is warranted for challenging vascular cases.
