Impact of preoperative antithrombotic discontinuation duration on clinical outcomes following hard channel surgery for chronic subdural hematoma

Insufficient preoperative antithrombotic discontinuation did not significantly affect major clinical outcomes in patients with CSDH undergoing hard-channel puncture drainage. However, it was associated with prolonged hospital stay. These findings support individualized preoperative antithrombotic management to optimize safety and efficacy while minimizing hospitalization duration.
