Abstract：Objective To investigate the clinical effect of minimally invasive drainage in the treatment of chronic subdural hematoma after brain injury,and to analyze the influence of complications.Methods 82 cases of patients with chronic subdural hematoma of brain injury were treated in our hospital from April 2016 to April 2020.They were randomly divided into two groups,the control group and the observation group.The control group was treated with drilling and drainage,and the observation group was treated with minimally invasive drainage.The clinical efficacy and the incidence of complications of all patients were observed and compared.Results all patients were reexamined by cranial CT on the 5th day after operation.The residual amount of hematoma,operation time and hospitalization time of the observation group were higher than those of the control group,and the Glasgow Coma index(GCS)score of the patients was significantly higher than that of the control group.After 3 months of follow-up,the clinical symptoms of subdural hematoma of all patients were eliminated.In terms of complications,the incidence of complications in the observation group was only 4.88%,which was significantly lower than 26.83% in the control group.Conclusion in the treatment of chronic subdural hematoma after brain injury,the effect of minimally invasive drainage is more significant than that of drilling drainage,which is helpful to prevent the increase of postoperative complications.
