Assessment of recurrence risk factors in patients with chronic subdural hematoma: regarding surgical treatment

Abstract

Background and Purpose: Burr hole craniostomy for symptomatic chronic subdural hematoma (CSDH) is safe and effective with recurrence rate of up to 33%. The purpose of this study is to analyze the postoperative recurrence risk factors for the CSDH.

Methods: We collected CSDH patient’s clinical data in our institute for the past two years. We divided CSDH patients into recurrence group and no–recurrence group. Mean age, gender, presence of comorbidities, hematoma thickness, presence of midline shift, niveau formation, irrigation and drainage use are compared between the two groups.

Results: In the recurrence group, hematoma thickness was significantly higher than no–recurrence group. Irrigation and drainage was significantly higher in the no–recurrence group.

Conclusions: Irrigation and drainage might reduce recur­rence of CSDH.
