Analysis of risk factors predicting recurrence of chronic subdural hematoma
Journal Title: Nepal Journal of Neuroscience - Year 2018, Vol 15, Issue 2
Abstract
Recurrences after evacuation of chronic subdural hematoma are seen in 2-33% of cases with various surgical approaches. Various demographical, clinical, radiological, surgical and postoperative management strategies have been explored as the possible predictors of recurrence. We performed a retrospective analysis in 160 patients with chronic subdural hematoma with an aim to analyze the post-operative recurrences and factors associated with it. Various sociodemographic and clinico-radiological parameters were studied against the rate of recurrence after surgery using Chi square/Fischer Exact Test. Factors showing signifi cant association on univarate analysis were then analysed using binary logistic regression. The rate of recurrence of CSDH in our study was 5% and the mean duration of recurrence was 33 days. Chronic alcohol use (p=0.007) and intraoperative brain expansion ((p=0.001) were the two factors associated with recurrence of CSDH. On binary logistic regression chronic alcohol use (wald-6.467, p=0.011) and intraoperative brain expansion (wald= 6.674, p=0.010) were both associated signifi cantly with recurrence of CSDGH with an odds of 7.804 and 0.058 respectively
