ABSTRACT
OBJECTIVE:
To investigate therapeutic progress of cerebral intravascular stent, and to evaluate biocompatlbility with host.METHODS:
Articles were collected from CNKI and Medline database with the keywords of "cerebrovascular disease, stent, and therapy" in both Chinese and English from 1989 to 2009. Among 53 articles, 22 were included according to inclusion and exclusion criteria; while the included articles were summarized in the fields of therapeutic progress of cerebral intravascular stent,complication following cerebral intravascular stent implantation, and biocompatlbility of cerebral intravascular stent in order to investigate the biocompatibility of various stents.RESULTS:
Cerebral intravascular stent was mainly used to treat cerebral artery stenosis, cerebral aneurysm, venous sinus stenosis, and thrombus. Complications following cerebral intravascular stent implantation included carotid sinus syndrome,hypertransfusion syndrome, cerebral angiospasm, thrombosis, and restenosis. Pre-enlargement prior to implantation in the stenotic region played an important role in avoiding deformation and displacement of stent. Restenosis correlated to stent types following cerebral intravascular stent implantation. For example, metal stent could promote thrombosis; however, polymer which had an excellent biocompatibility to vessel wall was superior to metal stent, thus it could prevent endomembrane proliferation following implantation. Metal-coated stent could inhibit aggregation of platelet; additionally, drug stent could effectively prevent restenosis via high-concentration drug release for a long term.CONCLUSION:
Cerebral intravascular stent is considered as an ideal tool to treat cerebrovascular disease. Metal stent has a poor compatibility, but polymer stent, coating stent, and drug stent have a good compatibility.
