Literature evaluation and current status of extracranial vertebral artery stenting in China / 中国脑血管病杂志

ABSTRACT

Objective To summarize the development and current status of the technology of extracranial vertebral artery stenting(VAS) in China based on published Chinese literatures. Methods Using computer retrieval and manual retrieval method,China National Knowledge Infrastructure (C N K I),Wanfang Database, Weipu, and Sinomed were searched. Data were collected form identified domestic literatures on VAS published until June 2018. Two researchers independently read and screened the articles according to inclusion and exclusion criteria, and then the data were checked by a third researcher. A comprehensive evaluation of VAS in China was performed according to regional distribution, department distribution, anesthesia type,stent use, surgical effect,clinical outcome, complications, medication and restenosis. Results (1) A total of 1 429 relevant literatures were retrieved and 178 articles with low overall quality were recruited,including 2 randomized controlled trials ( 100cases and follow-up > 1 year. The incidence rate of restenosis was 25.4% (430cases). Conclusions VAS technology has been widely used in China. However, VAS treatment should be completed by qualified hospitals with corresponding technical operation specifications. The guidance of VAS in China should be based on and further supported by rigorous clinical trials with high-quality research designs.
