  • Risk of hemorrhage in pregnant cerebral arteriovenous malformation patients: a systematic review

    ObjectiveTo systematically review the risk of hemorrhage in pregnant cerebral arteriovenous malformation (CAVM) patients. MethodsThe Web of Science, PubMed, Cochrane Library, WanFang Data, VIP and CNKI databases were electronically searched to collect clinical studies related to hemorrhage in pregnant CAVM patients from inception to June, 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 13.1 and R 4.0.4 software. ResultsA total of 13 studies involving 2 273 patients were included. The results of meta-analysis showed that the pooled incidence of hemorrhage in pregnant CAVM patients was 0.18 (95%CI 0.12 to 0.24). The subgroup analyses were carried out based on world regions and the study duration, with the higher pooled incidence of 0.37 (95%CI 0.05 to 0.80) in Europe and 10 to 20 years of study duration of 0.37 (95%CI 0.17 to 0.57). Conclusion Current evidence shows that the incidence of hemorrhage in pregnant CAVM patients is about 18%. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
