Factors Deciding Outcome of Chronic Subdural Hematoma

Abstract

Background: C.S.D.H is a common condition in neurosurgical practise found widely in elderly people. Recurrence following surgical decompression is not uncommon and depends on mode of surgery. Objective: To identify the best mode of treatment in view of recurrence prevention. Methods: Cases of C.S.D.H operated at our hospital between 2018 - 2020 were reviewed prospectively. Data included preoperative and postoperative symptoms, type of surgical treatment, use of surgical drain and clinical outcome. Results: A total of 240 cases were analysed. And overall recurrence was 9.5 %. The risk of recurrence was higher in patients who undergone surgery without drain application, twist drill aspiration of hematoma and septate CSDH operated with burr hole craniotomy. Conclusion: Burr hole craniostomy with drain had lower recurrence rate in comparison to twist drill aspiration. Septate SDH may need craniotomy to prevent recurrence.
