Brief summary
Prevention for the Restenosis of Intracranial artery Stent Implantation Treated with herbal medicine C117--PRISIT Trial
Detailed description
Intracranial artery stenosis (ICAS) is a common cause of ischemic stroke worldwide. At present, percutaneous transluminal angioplasty and stenting serve as a possible treatment option for ICAS patients, however, intracranial in-stent restenosis(ISR) limited its use in clinical practice, which led to recurrent stroke even death, meanwhile, From the point of chinese medicine, in-stent restenosis(ISR) regard as the unhealthy environmental influences with shapes, therefore, we have design two control group on the basis of conventional secondary prevention, one use herbal medicine for blood-acting and stasis-dissolving, and another use the similar looking placebos, after 12 months of treatment, we will evaluate the rate of all-cause stroke and all-cause mortality, moreover, we also record the Vascular restenosis rate which may cause recurrent ischemic stroke, the aim of this study was to evaluate the safety and efficacy of herbal medicine C-117.
Interventions
C117 formula including 2 herbals and 2 insects

Secondary
| Measure | Time frame | Description |
|---|---|---|
| The rate of intracranial in-stent restenosis | After 12 months follow-up period,record the rate of intracranial in-stent restenosis | After drug-use 12 months,observe the rate of intracranial in-stent restenosis where stent implantation.throgh the test of TCD, digital subtraction angiography. |
| The complications of intracranial in-stent restenosis | After 12 months follow-up period,record the complications of intracranial in-stent restenosis | After drug-use 12 months,observe the complications of intracranial in-stent restenosis,including TIA and stroke,even death. |
| NIH Stroke Scale (NIHSS) | After 12 months follow-up period | At the time of 6 and 12 months,we will have a follow-up to assess the patient's NIHSS |
| Bathel index | After 12 months follow-up period | At the time of 6 and 12 months,we will have a follow-up to assess the patient's NIHSS, Bathel index |
| modified RANKIN score. | After 12 months follow-up period | modified RANKIN score. |
