Abstract:
Objective To analyze the relationship between CT characteristics of chronic subdural hematoma (CSDH) and its recurrence, as well as relevant pathological mechanism. Methods The study involved 178 patients with CSDH who underwent surgery, of whom 38 patients (40 lesions) experienced recurrence of CSDH. Univariate and multivariate logistic analyses were performed to assess the correlation among CT characteristics ( including side, density, width, subtype and midline shift of the hematoma) and CSDH recurrence. Results ( 1 ) The width of hematoma, midline shift, type of hematoma were found to be correlated with the recurrence of CSDH in the univariate analysis. The odds ratio (OR)and 95% confidence interval (CI) value of patients with hematoma width ＞30 mm, midline shift ＞10 mm and the separated type were 18. 400 (2.024-167. 301 ), 4. 643 ( 1. 815-11. 877 ) and 14. 385 (3. 601-57.467 ), respectively. (2) The midline shift and type of hematoma were found to be correlated with the recurrence of CSDH in the multivariate analysis, when the OR and 95% CI value of patients with hematoma midline shift ＞ 10 mm and separated type were 5. 280 ( 1. 339-20. 823) and 19. 125 (4. 175-87.619), the OR and 95% CI value of patients with hematoma width ＞30 mm was 14. 838 ( 1. 353-162.698). Conclusions Type of hematoma and midline shift are found to be independently correlated with the recurrence of CSDH, and the width of hematoma is also related with its recurrence.
