Those patients who have stenosis of more than 50% of the common carotid artery or internal carotid artery (diagnosed by ultrasonography or angiography), with neurological symptoms (transient cerebral ischemic stroke or cerebral stroke), or who have stenosis of more than 80% of the common carotid artery or internal carotid artery (diagnosed by ultrasonography or angiography) even if there are no neurological symptoms.

NO
To investigate the safety and efficacy of cilostazol as an antithrombotic therapy during CAS.
Safety,Efficacy
Exploratory
Pragmatic
Phase IV
1Cumulative incidence of death, stroke, or myocardial infarction within 30 days after CAS.
2Cumulative incidence of death or ipsilateral stroke between 31 days and 1 year after CAS.
1Cumulative number of target-vessel revascularization at 1 year after CAS.
2Cumulative number of restenosis at 1 year after CAS. Restenosis is defined as 50% or more stenosis diagnosed by angiography when cerebral infarction is suspected.

Treatment
Medicine |
Patients are to be administered concomitantly with aspirin 100 mg once a day and cilostazol 100 mg or 200 mg twice a day from at least 3 days before CAS. The combination therapy is to be continued for 3 months. After that (Month 4 and thereafter), patients are to be administered only with cilostazol twice a day.
When a staged stenting is to be carried out, patients are to be administered concomitantly with aspirin and cilostazol from at least 3 days before predilation. After postdilation, the concomitant therapy is to be continued for 3 months. After that, patients are to be administered only with cilostazol for 9 months.
Patients are to be evaluated for the endpoints (see above) before and during CAS, and 1 and 12 months after CAS.
