Medicine
Interventions/Control_1 Standard prescription (Aspirin 100mg/day and Clopidogrel 75mg/day) are started 2 weeks before the endovascular surgery. Platelet function is checked on the day before the surgery. Patient with low~no response to Clopidogrel is changed to Prasugrel (loading dose 20mg, then, 3.75mg/day for 3 days). When stent is used, Prasugrel is contineud for 3 months.
Interventions/Control_2 Clopidogrel is continued for patient with normal response to Clopidogrel (75mg/day for 3 days). When stent is used, Clopidogrel is contineud for 3 months.
