Outcome Measures

Primary Outcomes (1)

  • National Institutes of Health Stroke Scale score

    Patient's neurologic deficits will be evaluated with the National Institutes of Health Stroke Scale (NIHSS) score 1 year after stent implantation or antiplatelet medication or antiplatelet medication only.

    1 year after treatment

Secondary Outcomes (2)

  • Changes of Barthel index

    0.5, 1, 2, 3 years after treatment

  • Carotid stenosis rate

    1 year after treatment

Study Arms (2)

Enterprise stent implantation group

EXPERIMENTAL

Patients with atherosclerotic ischemic stroke will be randomly allocated to receive Enterprise stent implantation in combination with antiplatelet medication for carotid artery stenosis.

Device: Enterprise stent implantation

Only aspirin medication group

EXPERIMENTAL

Patients with atherosclerotic ischemic stroke will be randomly allocated to receive only antiplatelet medication for carotid artery stenosis.

Drug: Only aspirin medication

Interventions

Enterprise stent system (Johnson \& Johnson (Shanghai) Medical Equipment Co.,Ltd., China) is a closed loop self-expanding stent system that is made of Ni-Ti alloy. It consists of a self-expanding stent and a delivery system.

Also known as: Enterprise self-expanding stent system implantation
Enterprise stent implantation group

Only aspirin medication will be conducted, initial dose is 300 mg/d, 200 mg/d 6 months later, and 100 mg/d 1 year later.

Also known as: Drug intervention
Only aspirin medication group
