Brief Summary

This study is a prospective, multi-center, real world, observational study, which aims at evaluating the safety, efficacy and economic cost of endovascular treatments for endovascular therapies in tosaka III (totally occluded) in-stent restenosis.It is estimated that 300 subjects diagnosed with tosaka III in-stent restenosis and receive endovascular treatments will be enrolled in nine centers from April 2021 to December 2022 nation-widely. All the subjects will be under follow-up for 24 months. There is no restriction on the endovascular techniques. The primary outcomes include clinical-driven freedom from TLR at 24 months.

Outcome Measures

Primary Outcomes (1)

  • Freedom from clinically-driven TLR

    CD-TLR was defined as any reintervention within the target lesion(s) because of recurrent symptoms. Freedom form CD-TLR were defined as the rates of the number of patients who did not receive reintervention verse the number of patients during the follow-up period.

    24 months

Secondary Outcomes (6)

  • Primary patency

    1month, 6 months,12 months, 18 months ,24 months

  • Technical success rate

    30 days

  • Incidence of major adverse events.

    1month, 3 months,6 months, 12 months ,24 months

  • Freedom from TLR

    1month, 6 months,12 months, 18 months

  • Vascular quality of life questionnaire(VascuQol)

    3 months,6 months, 12 months ,24 months

  • +1 more secondary outcomes

Study Population

The patients with Tosaka III in-stent restenosis lower extremity femoropopliteal artery.

You may qualify if:

  • Tosaka III In-stent restenosis after stent implantation in PAD patients (Including acute and subacute thrombotic lesions).
  • Rutherford grade 2-5.
  • Stents should be located in the femoropopliteal artery.
  • The stenosis of iliac artery on the affected side is less than 30% or the residual stenosis after treatment is less than 30%.
  • Informed consent has been signed

You may not qualify if:

  • Tosaka I or II in-stent restenosis.
  • Stents are located in iliac artery or artery below the knee, or the preoperative CTA showed type 3 or 4 stent fracture.
  • Rutherford Grade 6.
  • Thromboangiitis obliterans (TAO)-based, arteritis-based or connective tissue disorder-based FP-ISR.
  • Intraoperative conversion to hybrid or open surgery.
  • Patients refusing to sign informed consent forms.
  • Life expectancy of patients is less than 12 months.
  • The pregnant or nursing patients.
  • The patients with severe ischemia of lower extremity who would receive major amputation in plan.
  • Patients in whom antiplatelet or anticoagulant therapy is contraindicated.
  • Myocardial infarction or stroke within 3 months prior to enrolment.
  • Patient with known allergy to contrast agents or medications used to perform endovascular intervention.
  • Patients participating in another research study involving an investigational agent (pharmaceutical, biologic, or medical device) that has not reached the primary endpoint.
  • Patients who refuse to cooperate with long-term follow-up or who have difficulty communicating.
