Abstract：Objective To investigate the relationship between hematoma recurrence and changes in the volume of chronic subdural hematoma (CSDH) during the perioperative period using CT volumetric analysis. Methods The study involved 54 cases of CSDH patients, including 64 hematoma. The association between recurrence rate and CT findings was investigated. Results Eleven patients (20.4%) experienced postoperative recurrence. A higher pre-operative (>120 ml) hematoma volume and/or pre-discharge subdural fluid volume (>22 ml) were significantly associated with higher recurrence. The probability of non-recurrence for values below these thresholds was 92.7%and 95.2%respectively. CSDH with larger preoperative (>15.1 mm) and/or residual widths (>11.7 mm) also had significantly increased recurrence rates. Conclusions Volumetric quantitative CT can provide strong evidence that changes in the residual fluid volume during the"self-resolution"period can be used as significant radiological predictors of recurrence.
