Value of cortical atrophy scale and cerebral atrophy index in predicting chronic subdural hematoma in elderly patients / 中华老年心脑血管病杂志

ABSTRACT

Objective To study the value of CAS and brain atrophy index (BAD in predicting CSDH in elderly patients.Methods Two hundred and sixty-eight elderly head trauma patients were divided into CSDH group (n=40) and CSDH-free group (n=228).Their CSF volume,intracranial volume,brain volume,ventricular volume,subarachnoid space volume were measured by MR scanning,their BAI,Evans index,FHI,CAS score and clinical data such as gender and age were recorded,their clinical data and laboratory parameters were compared.Relationship between different factors in elderly CSDH patients was analyzed.The risk factors for CSDH in head trauma patients were analyzed by univariate and multivariate logistic regression analysis.Results The BAI and CAS score of moderate and severe brain atropy were significantly higher in CSDH group than in CSDH-free group (P＜0.01).Correlation analysis showed that BAI was negatively related with brain volume and positively related with ventricular volume and subarachnoid space volume,ventriclular volume was positively related with subarachnoid space volume and Evans index,subarachnoid space volume was positively related with Evans index (r=0.35,P=0.02),Evans index was positively related with FHI (r=0.23,P =0.03).Univariate and multivariate logistic regression analysis showed that BAI≥7.15％ on admission and CAS score of moderate and severe brain atrophy increased the risk of CSDH in elderly head trauma patients (P＜0.05).Concluson CAS score and BAI can predict the occurrence of CSDH in elderly head trauma patients.
