Objective: Recent meta-analyses propose burr hole (BH) drainage as the most efficient choice for treatment of chronic subdural hematoma (CSDH). But recurrence rate after BH drainage varies from 0.35% to 60%. In this study, we investigated the risk factors for the recurrence of CSDH after BH drainage.
Methods: We retrospectively reviewed 182 patients with CSDH treated by BH drainage. Univariate and multivariate analyses were performed to identify risk factors for recurrence of CSDH.
Results: Twenty patients (11%) underwent a reoperation because of the recurrence of CSDH during the study period. Liver disease (p=0.009), bilateral CSDH (p=0.034) and disturbance of consciousness (p=0.036) were related risk factors for recurrence of CSHD. Among them, liver disease (p=0.016) and bilateral hematoma (p=0.046) were independent risk factors for recurrence of CSDH by multivariate analysis.
Conclusion: Liver disease and bilateral hematoma were independent risk factors for recurrence of CSDH. If more data is collected, we can find independent factor for recurrent CSDH among liver disease.
