Comparison of Primary Long Full Coverage Stenting vs Primary Short Spot Stenting for Long Femoropopliteal Artery Disease.
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.

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.
