【摘要】BACKGROUND: Novel endovascular stent materials have become the research hot spot in the treatment of ischemic stroke. OBJECTIVE: To analyze the features of endovascular stent materials and the treatment effect on ischemic stroke. METHODS: Related databases were searched by the first author with computer at December 2012 for the related articles published from 2003 to 2012. The Chinese key words were
“ischemic
stroke,
endovascular
stent,
stent
material,
interventional treatment”. A total of 120 articles were screened out, and 24 articles were included for the final review according to the inclusion criteria. RESULTS AND CONCLUSION: Long-term storage of bare-metal stents in the blood may lead to corrosion, metal ions dissolution and coagulation; the surface modification of the metal material could be used to solve the problem of metal material storage in order to improve the blood compatibility of the metal materials. Therapeutic drugs were coated on the surface of stent which can help the drugs release with high concentration continuously, and this method can inhibit restenosis after stent implantation. Film-covered endovascular stent was covered with degradable or non-degradable
