    Abstract

    Objective

    The purpose of this study was to examine the corelation of the recurrence rate and the use of antiplatelet agent or anticoagulant agent on chronic subdural hematoma patient group, and to find the appropriate time that reuse the agents.

    Methods

    Between January 2007 and December 2008, 37 patients has undergone burr hole trephination for chronic subdural hematoma. Among them, 8 patients had been used antiplatelet or anticoagulant agent (agent using group). The other patients were agent non-using group. We reviewed medical and laboratory records retrospectively.

    Results

    Preoperative laboratory finding including prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalized ratio (INR), bleeding time (BT) were all within normal range on agent using group. Follow up laboratory findings were also all within normal range. The recurrence rate on agent using group was not superior to agent non-using group (12.5% : 13.8%). The patients with heart problem were took medication again after drainage catheter removal (postoperative second or third day). The prescribed medicines were restarted to old cerebral infarction patients on postoperative seventh day.

    Conclusion

    The use of antiplatelet or anticoagulant agents are not influenced recurrence rate on chronic subdural hematoma operation if the patients have no bleeding tendency before operation. Re-administration of agents may be possible within postoperative seventh day.
