Abstract:

BACKGROUND: Imaging detection has been widely used in clinical ischemic cerebrovascular disease, which is noninvasive, simple and rapid.
OBJECTIVE: To observe imaging morphological changes following endovascular stent implantation to explore safety and values of endovascular stent in ischemic cerebrovascular disease.
METHODS: A computer-based online search was performed for related articles published from January 1993 to October 2009 with the key words “vascular stent; scaffold; restenosis; endothelialization; imaging evaluation”. Articles related to imaging morphological evaluation of intracranial target vascular restenosis following stenting of different materials. Repetitive studies or Meta analysis was excluded. A total of 30 articles were selected to discuss safety and imaging evaluation of different materials of stent for ischemic cerebrovascular disease.
RESULTS AND CONCLUSION: Intracranial target vascular restenosis following stenting of different materials was observed during follow-up by imaging to identify restenosis and confirm cause, which facilitates evaluation of risks and effect of stent materials. Imaging is sensitive, specific and accurate to identify morphological changes following different materials of stent implantation to help material selection and evalution of embolus shedding at lesioned site.
