HEMATOMA, RECURRENCE
Early cessation of subdural drain production after single burr hole evacuation of CSDH seems to be associated with an increased risk of recurrent hematoma. Patients with early cessation of drainage did not benefit from further drain time. This group of patients is highly interesting, and a better understanding of the reasons for early drain cessation could significantly reduce the overall recurrence rate for CSDH. The findings of the present study, calls for a randomized trial to determine the potential beneficial effects of individual, personalized drainage time compared to a fixed drainage time in CSDH patients.
