Study summary

Peripheral arterial disease (PAD) is a widespread pathology affecting over 200 million adults globally and is primarily caused by atherosclerosis. It leads to peripheral arterial stenosis, commonly in the lower extremities, resulting in symptoms ranging from intermittent claudication to chronic limb-threatening ischemia (CLTI). Endovascular interventions are currently considered first-line treatment approaches for PAD. Laser atherectomy offers a minimally invasive endovascular option to effectively debulk atherosclerotic steno-occlusive lesions prior to balloon angioplasty, minimizing vessel dissection and the need for stenting. Additionally, recent multicenter randomized controlled trials have demonstrated that sirolimus-coated balloon (SCB) angioplasty is a safe and effective treatment method for PAD. Although safety and efficacy of both laser atherectomy and SCBs are recognized, their combination for the treatment of patients with CLTI has not been adequately investigated. This research pilot study aimed to evaluate the safety and efficacy of combined laser atherectomy and SCB angioplasty for the treatment of CLTI. Key endpoints of the study include technical success rate, major adverse events, rates of limb salvage and target lesion reintervention, clinical improvement and overall patient survival rate.

Study population

Patients suffering from Rutherford-Becker 4 to 6 CLTI, due to infrainguinal arterial disease, scheduled to undergo endovascular treatment using laser atherectomy and SBC angioplasty based on MDT decision.

No restrictions to lesion length, grade of calcification and extent of tissue loss, as long as the limb was jugded salvagable by the hospital's multidisciplinary CLTI team.

Inclusion criteria

  • Rutherford-Becker 4 to 6 CLTI
  • MDT decision for endovascular treatment using laser atherectomy and SBC angioplasty
  • Infrainguinal arterial disease (de-novo stenosis or occlusions, restenosis, instent-restenosis) including the common femoral artery, the femoropoliteal artery and infrapopliteal arteries (including distal infrapopliteal segments and pedal arch disease)
  • Patients with patent iliac artery inflow to the target limb
  • No restrictions to lesion length, grade of calcification and extent of tissue loss, as long as the limb was jugded salvagable by the hospital's multidisciplinary CLTI team

Exclusion criteria

Exclusion Criteria:

  • Acute limb ischemia including acute on chronic events
  • Iliac artery disease or bypass angioplasty stenosis
  • Subintimal lesion crossing
  • Standard contraindications to endovascualr treatment
  • Pre-scheduled majore above the knee amputation
  • Contraindication to antithrombotic therapy

What researchers measure

Primary outcomes

  1. Limb salvage

    No major (above the knee) amputation

    Time frame: 6 months

  2. Clinically-driven target lesion reintervention (CD-TLR)

    Any repeat intervention (endovascular or open surgical) performed at the target lesion due to a recurrence, deterioration, or lack of improvement in clinical symptoms, or in the presence of a new or worsening ischemic lesion.

    Time frame: 6 months

  3. Major adverse events (MAE)

    A composite of device- or procedure-related major complication, death, unplanned major amputation of the target limb, and clinically driven target lesion reintervention (cd-TLR) occurring through 6 months post-procedure.

    Time frame: 6 months

Secondary outcomes

  1. Complete wound healing

    Complete wound healing of ischemic tissue loss (gangrene, ulcer, surgical wound6) of the target limb following intervention

    Time frame: 6 months

  2. Survival

    Patients' mortality rate

    Time frame: 6 months

  3. Technical success

    Uncomplicated endovascular recanalization of the target lesion(s) without flow-limiting dissection (≥ type C) and without bail-out stenting

    Time frame: 1 hour after the index procedure

  4. Clinical improvement

    Imoprovement by at least one stage in Rutherford-Becker classification

    Time frame: 6 months
