Gliederung

Text

Objective: In the past we analyzed the literature on chronic subdural hematoma for the efficiency of different operative treatment options. We then implemented our findings in an optimized treatment algorithm (OA-EBM group) and compared the results to a control group treated by the standard departmental surgical technique (SDST group) in a prospective design.

Methods: Symptomatic patients with chronic subdural hematoma who fulfilled the inclusion criteria were randomly assigned to one of two treatment arms according to the duty roster of the clinic. For the OA-EBM-algorithm only one burr hole, intraoperative rinsing and a closed system drainage was mandatory. A two-catheter-technique was used to reduce intracavital air. Final endpoints were recurrence and the amount of intracranial air on postoperative ct-scan.

Results: A total of 93 out of 117 patients joined the study accounting for 113 cases because of 20 patients with bilateral hematomas. Demographic data of 68 cases treated by the standard protocol did not differ from 45 cases treated by the EBM-algorithm. Recurrence rate was 18% (12 cases) in the SDST group versus 2% (1 case) in the EBM group (p < 0,05). The amount of intracranial air was significantly lower in the OA-EBM group (3 ± 0.7 cm3 vs 5 ± 0.9 cm3) with p = 0.04. In the standard group ct-scanning was performed slightly earlier (3 ± 0.2 days vs 3.6 ± 0.2 days, p = 0.015). Comparing only non-recurrent cases of both groups no significant difference was apparent.

Conclusions: Implementation of EBM key factors into a treatment algorithm for chronic subdural hematoma can improve outcome in a typical neurosurgical department by means of recurrence and the amount of postoperative air within the hematoma cavity.
