The comparison of STA-MCA bypass and BMT for symptomatic internal carotid artery occlusion disease: a systematic review and meta-analysis of long-term outcome

Abstract Background Superficial temporal artery (STA)-middle cerebral (MCA) bypass surgery is now being widely used in moyamoya disease, and its therapeutic value SICAO remains divergent. Methods A systematic search was performed PubMed, EMBASE, Cochrane Databases Feb. 2020 updated Jun. 2019. We have strict inclusion exclusion criteria. Bias Risk Assessment Tool to assess the quality of included RCTs. Review Manager 5.3 for analysis results terms comparing STA-MCA BMT. For dichotomous variable outcomes, risk ratios (RRs) 95% confidence intervals (95%CIs) were calculated assessment. Results The total patient cohort consisted 2419 patients, whom 1188 (49.1%) patients had been grouped 1231 (50.9%) divided into BMT group. Mean follow-up 29 months. RR seven studies 1.01, interval .89–1.15, with statistical significance, Z = .13, P .89, sustaining that not superior symptomatic carotid occlusion disease. Conclusions associated similar rates a composite long-term stroke. And overall stroke mildly higher At present, each should receive more precise treatment, by reasonably assessing individual differences reduce recurrence rate
