Summary

Rotary atherectomy effectively treated superficial femoral artery disease, achieving 76% satisfactory permeability. Mid-term results showed 80% permeability at six months, indicating a promising treatment for peripheral artery disease.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Endovascular Therapy

Background:

  • Superficial femoral artery (SFA) disease significantly impacts patient mobility and quality of life.
  • Traditional treatment options for SFA occlusions have limitations, especially in complex or calcified lesions.
  • Rotary atherectomy offers a minimally invasive approach to address challenging SFA obstructions.

Purpose of the Study:

  • To evaluate the efficacy and safety of rotary atherectomy for treating superficial femoral artery occlusions.
  • To assess procedural success rates, including lesion traversal and achievement of residual stenosis.
  • To determine the mid-term patency rates and clinical outcomes following rotary atherectomy.

Main Methods:

  • A cohort of 44 patients with symptomatic SFA occlusions underwent treatment with rotary atherectomy between June 1988 and September 1989.

  • Vascular echography was used pre-procedure to assess intraluminal calcification.
  • Rotary atherectomy was often combined with conventional balloon angioplasty.
  • Follow-up included day-3 angiography and clinical assessment of lower limb/upper limb Doppler index.

    • Main Results:

    • Successful lesion traversal was achieved in 87% of cases (40/46), even in lesions impermeable to traditional guidewires.
    • Satisfactory permeability (residual stenosis <30%) was obtained in 76% of patients at hospital discharge.
    • The mean lower limb/upper limb Doppler index improved significantly from 0.44 to 0.89 post-treatment.
    • Mid-term permeability at 6 months was 80% among primary successes, with a low rate of complications like embolism (2 cases).

    Conclusions:

    • Rotary atherectomy is an effective and safe endovascular technique for treating superficial femoral artery occlusions, particularly in calcified or complex lesions.
    • The procedure leads to significant improvement in limb perfusion and satisfactory mid-term patency rates.
    • This approach represents a valuable alternative to surgical intervention for selected patients with peripheral artery disease.
