简要总结
The purpose of this study is to evaluate the efficacy and safety of the ticlopidine + ginko biloba compared to clopidogrel in clopidogrel resistant patients undergoing carotid artery stent placement. The investigators hypothesized that ticlopidine + ginko biloba is superior than clopidogrel in terms of post-stent ischemic lesions in these patients without serious complications.
