  • Intracranial Angioplasty with Gateway-Wingspan System for Atherosclerotic Stenosis: A Meta-analysis of Single rate

    ObjectiveTo systematically review the safety and validity of the treatment of intracranial atherosclerosis diseases (ICAD) by using Wingspan stents, and to provide the reference for clinical practice and research. MethodsDatabases such as the PubMed, The Cochrane Library, EMbase, Cochrane Central Register of Controlled Trials, CBM, CNKI and VIP were searched for studies concerning the safety and validity of the treatment of intracranial atherosclerosis diseases (ICAD) by using Wingspan stents from January 1st, 2005 to January 10th, 2014. Randomized controlled trials (RCTs), non-randomized controlled trials, case-control studies, cohort studies and case series were all included. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data. Then, meta-analysis was performed by using the R software. ResultsA total of 34 studies (2 RCTs, 22 cohort studies, and 10 case-control studies) involving 2 511 patients were included. The results of meta-analysis showed that:operation success rates was 96.75% (95%CI 95.82% to 97.48%), 30 day rates of the end point events was 8.75% (95%CI 7.61% to 10.04%), 1 year rates of the end point events was 13% (95%CI 11.47% to 14.70%), total mortality was 2.98% (95%CI 2.16% to 4.10%), incidence of in-stent restenosis was 21.76% (95%CI 18.27% to 25.71%), the ratio of the patients with symptomatic restenosis and total patients was 6.50% (95%CI 4.89% to 8.60%), and the ratio of the patients with symptomatic restenosis and total patients with restenosis was 26.06% (95%CI 19.94% to 33.29%). ConclusionCurrent evidence shows that treatment of ICAD by using Wingspan stents is effective and safe. However, this conclusion should be approved by further higher quality RCTs.
