NCT01359423

  Purpose

Hypothesis: Primary long full coverage stenting is superior to primary short spot stenting in the treatment of long (≥80 mm) femoropopliteal artery lesions.

Study design :

  • Prospective, randomized, multi-center study
  • A total of 220 subjects with symptomatic peripheral artery disease of lower limbs who meet all inclusion and exclusion criteria will be included.
  • Patients will be randomized in a two by two factorial manner according to the strategy of stenting (long versus short stenting) and the additional use of cilostazol. Each randomization of the enrolled subjects will be done 1:1.
  • Patients will be followed clinically for 1 year after the procedure.
  • Angiographic or CT follow-up will be performed at 1 year.

Condition Intervention
Claudication
Drug: Percutaneous transluminal angioplasty of femoropopliteal artery lesions with primary long
Drug: short stenting for the primary outcome and use of cilostazol for 12 months for secondary outcome.

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label

Primary Outcome Measures:
  • The rate of binary restenosis [ Time Frame: 12months after the index procedure ] [ Designated as safety issue: No ]
    The rate of binary restenosis (stenosis of at least 50 percent of the luminal diameter) in the treated segment 12 months after intervention, as determined by computed tomographic angiography (CTA) or catheter angiography according to the stenting strategy


Secondary Outcome Measures:
  • Ankle-brachial index, etc [ Time Frame: at 12 months according to the stenting strategy ] [ Designated as safety issue: No ]
    1. Ankle-brachial index at 12 months according to the stenting strategy
    2. Maximal walking distance at 12 months according to the stenting strategy
    3. The rate of reintervention including repeat endovascular therapy or bypass surgery involving the target lesion
    4. The rate of limb salvage at 12 months according to the stenting strategy
    5. The rate of major adverse cardiovascular events (MACE) at 12 months according to the stenting strategy

Arms Assigned Interventions
Experimental: long coverage
Primary long full coverage stenting
Drug: Percutaneous transluminal angioplasty of femoropopliteal artery lesions with primary long
Patients will be randomized in a two-by-two factorial manner according to the use of IVUS guidance (IVUS guidance vs. no IVUS guidance) for the PCI and the duration of dual anti-platelet therapy (100 mg/day aspirin and 75mg/day clopidogrel for 6 months vs. 12 months) after PCI. Each randomization of the enrolled subjects will be done 1:1.
