Assessment of risk factors for postoperative complications in meningioma / 实用放射学杂志

ABSTRACT

Objective To investigate the risk factors that may affect postoperative complications in patients with meningiomas. Methods Of all 300 patients with diagnosed pathologically intracranial meningiomas undergoing resection were retrospectively ana-lyzed in terms of clinical datas and radiological features of preoperative MRI.These patients were divided into two groups according to whether postoperative complications occurred after tumor resection.Both univariate and multivariate regression models were used to analyze the effect of patient age and several MRI characteristics on postoperative complications.Results There were several signif-icant differences between the two groups in patient age,tumor location,tumor size,shape of tumor,wrapping around nerves and blood vessels,and tumor enhancement (P <0.05).According to the results of multivariate Logistic regression analysis,tumor loca-tion,tumor size,wrapping around nerves and blood vessels,and tumor enhancement were independently identified risk factors in the prediction of postoperative complications associated with meningioma resection.Conclusion The features of preoperative MRI may be useful for clinicians in predicting postoperative complications of intracranial meningiomas,and can provide imaging evdience for effective treatment and prognostic assessment in patients with meningiomas.
