Medicine
Interventions/Control_1 1.Cilostazol group: Treatment with cilostazol 200 mg/day BID (morning and evening) and aspirin at 100 mg/day will be started 3 to 7 days prior to EVT and continued until the end of the 2-year follow-up period.
Interventions/Control_2 2.Non-cilostazol group: Treatment with aspirin 100 mg/day will be started 3 to 7 days prior to EVT and continued until the end of the 2-year follow-up period.

In both groups, oral treatment with ticlopidine hydrochloride 200 mg/day BID (morning and evening) will be started 3 to 7 days prior to EVT and continued until 4 weeks after EVT (only stenting).
If dose reduction of cilostazol is required due to adverse drug reactions such as headache, the dosage may be reduced to 100 mg/day BID.

Key inclusion criteria Inclusion criteria
Patient criteria
Patients who meet all of the following criteria will be included in the study:
1. Chronic arteriosclerosis obliterans afflicting the femoropopliteal artery area*
(Rutherford classification 2-4) (see Appendix 1)
*Except for patients with acute (within 1 week after onset)/subacute (2 weeks to 1 month after onset) lower limb ischemia
2. Age: 20 years or older at the time of consent
3. Gender: Male or female
4. Patients who can be monitored for at least 2 years after surgery
(Patients who can undergo follow-up angiography 2 years after surgery)
Lesion criteria
1. Angiographically-confirmed new significant superficial femoral artery stenosis or occlusive lesions that are 30 cm long or less if stented
The inferior and superior poles of the superficial femoral artery are defined as the overlap with the bone in the adductor canal in the upper part of the femur, and the origin of the bifurcation, respectively.
2. At least 1 arterial runoff below the knee; stenosis lesions not limiting flow may be included.
In addition, patients with bilateral lesions or aorta-iliac artery lesions may be included. In patients with bilateral lesions, endovascular therapy should be conducted for each limb at an interval of 30 to 45 days.
3. Occlusive lesions may be included.
Key exclusion criteria Exclusion criteria
Patient criteria
Patients who meet any of the following criteria should be excluded from the study:
1.Patients with or at risk of hemorrhagic complications or patients with bleeding* tendency
*Bleeding such as hemophilia, capillary fragility, intracranial hemorrhage, gastrointestinal hemorrhage, urinary tract hemorrhage, hemoptysis, or vitreous hemorrhage may be aggravated.
2.Patients with congestive cardiac failure (NYHA III or IV or EF<30%)
3.Patients with a drug-eluting stent (DES)
4.Patients with creatinine of &#61619;2 mg/dL or patients with a history of serious adverse reaction such as leukopenia, hepatic dysfunction, or renal dysfunction, or hypersensitivity to any component of the study drug.
5.Pregnant or potentially pregnant women
6.Patients with acute lower limb ischemia
7.Patients who are not eligible for the study in the opinion of the attending physician.

Lesion criteria
Lesions that meet any of the following criteria should be excluded from the study:
1.Remnant inflow (aorta-iliac artery lesion)
2.Severe calcification (lesions not expected to be appropriately expanded)
3.No arterial runoff below the knee
