Summary
Peripheral arterial disease (PAD) patients experienced improved walking distance after Simpson atherectomy. This minimally invasive procedure effectively treated stenoses, enhancing limb perfusion and functional capacity in PAD patients.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Peripheral Arterial Disease
Background:
- Peripheral arterial disease (PAD) significantly impacts patient mobility and quality of life.
- Atherectomy is a key intervention for treating arterial stenoses in PAD.
- The Simpson atherectomy catheter offers a minimally invasive approach for plaque removal.
Purpose of the Study:
- To evaluate the efficacy of the Simpson atherectomy catheter in treating PAD.
- To assess improvements in walking distance and hemodynamic parameters post-procedure.
- To analyze the safety and outcomes of atherectomy in different stages of PAD.
Main Methods:
- Ten patients with PAD (8 Stage II, 2 Stage IV) underwent atherectomy using the Simpson catheter.
- Diagnosis involved clinical assessment, oxillography, Doppler ultrasound, treadmill testing, and angiography.
- Stenoses were located in iliac, superficial femoral, or popliteal arteries.
Main Results:
- Treadmill walking distance increased significantly, from 24-67m to 105-115m, a 35%-126% improvement.
- Ankle/arm ratio improved by a mean of 0.15 (Doppler ultrasound).
- No significant changes were observed at the stenosis site in follow-up angiography (3-6 months).
Conclusions:
- Simpson atherectomy is effective in improving walking distance and limb perfusion in PAD patients.
- The procedure demonstrates positive functional outcomes and hemodynamic benefits.
- Atherectomy provides a safe and effective treatment option for PAD, with sustained results.
