Abstract:

OBJECTIVE: To explore the reasons, occurrence mechanisms, as well as prevention methods for complications following cerebrovascular stent implantation.
METHODS: A computer-based online search was performed by the first author. The databases of Medline and CNKI were searched with year’s limitation of 1989-2009. According to the inclusive and exclusive criteria, the documents were screened, collected and evaluated from the following aspects: treating progress of cerebrovascular stent implantation; category and biocompatibility of cerebrovascular stent; as well as occurrence and prevention methods for complication following cerebrovascular stent implantation.
RESULTS: A series of complications, such as carotid sinus response, hyper-perfusion syndrome, cerebral angio spasm, bleeding at puncture locus, thrombosis, restenosis, as well as cerebral ischemia, would occur following cerebrovascular stent implantation. The complications were difficult to eliminate, but should be avoided by selecting correct implanting cases, elevating operator’s proficiency, enhancing understanding of complications, obeying perioperative management, as well as correctly and in-time treatment. Polymer stent, coating stent, and drug eluting stent presented superior biocompatibility to metal stent, which could prevent restenosis following implantation.    
CONCLUSION: Cerebrovascular stent implantation is one of the main treatments for cerebrovascular disease. Polymer stent, coating stent, and drug eluting stent exhibit excellent biocompatibility. The complications associate to stent implantation are preventable and remediable via sufficient preoperatively preparation, exactly operation and perioperative management.
