PURPOSE During intracranial meningioma surgery, surgeons experience considerable blood loss. Tranexamic acid (TXA) is used to minimize blood loss in several neurosurgical settings. However, evidence and trials are lacking. Our objective is to establish the most recent evidence on TXA safety and efficacy in intracranial meningioma surgery. METHODOLOGY Based upon Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), the authors collected fully published English literature on the administration of tranexamic acid for patients undergoing intracranial meningioma surgery using the keywords ["tranexamic acid" and "meningioma"] and its synonyms from Cochrane Central Database, the WHO International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, and PubMed. The primary outcome of the current study was total blood loss. The secondary outcomes include individuals requiring blood transfusion, anesthesia duration, surgical duration, and complication rate. Each included studies' quality was assessed using the JADAD scale. RESULTS For qualitative and quantitative data synthesis, we included five RCTs (n = 321) with the mean age was 47.5 ± 11.9 years for the intervention group and 47.2 ± 11.9 years for the control group. Our meta-analysis showed that the administration of TXA is associated with decreased total blood loss of standardized mean difference (SMD) of -1.40 (95% CI [-2.49, -0.31]), anesthetic time SMD -0.36 (95% CI [-0.63, -0.09]), and blood transfusion requirements RR 0.58 (95% CI [0.34, 0.99]). CONCLUSIONS The current study showed that TXA was associated with reduced intraoperative blood loss and intra- and postoperative blood transfusion. However, the studies are small. More RCT studies with a greater sample size are favorable.
