The overall rate of bleeding complications was higher in the therapeutic group compared with the control group, although this did not reach statistical significance (therapeutic group, 1.8%; control group, 0.74%; P = .051) with larger volume of drainage (therapeutic group, 292 ± 137 mL; control group, 179 ± 121 mL; P = .023) and seven spinal EDH in the treatment group.
