Summary
This study introduces a new rotational angioplasty technique for chronic peripheral artery occlusions. The method successfully reopened occlusions in most patients, offering a safe alternative to conventional treatments.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Biomedical Engineering
Context:
- Chronic peripheral artery occlusions (PAOs) significantly impair limb perfusion.
- Conventional angioplasty techniques have limitations in treating long and complex occlusions.
- Postmortem investigations informed the development of a novel rotational angioplasty device.
Purpose:
- To evaluate the safety and efficacy of a new motor-driven rotating catheter for treating chronic peripheral artery occlusions.
- To assess the success rate of rotational angioplasty in reopening completely occluded superficial femoral and popliteal arteries.
- To determine if this technique offers an advantage over conventional methods, particularly in challenging cases.
Summary:
- A flexible, blunt, motor-driven rotating catheter was used in 19 patients with chronic PAOs (mean occlusion length 10.9 cm, mean duration 17.2 months).
- Rotational angioplasty was performed at low speed (up to 200 rpm) via an 8 or 9 F sheath.
- Successful recanalization was achieved in 11 of 14 initial attempts. The technique was also effective in 2 of 3 patients after conventional method failure, with no reported vessel perforations.
Impact:
- The new rotational angioplasty technique demonstrates a high success rate for reopening chronic peripheral artery occlusions.
- This method provides a safe alternative, eliminating the risk of vessel wall perforation.
- The technique is applicable even in cases where conventional angioplasty has previously failed.
