P values were calculated using the Chi-square , Student’s t (a) or Wilcoxon rank sum tests (b). Groups: A, minimal invasive puncture and drainage; B, decompressive craniectomy; BP: blood pressure; SPB systolic blood pressure. DBP: diastolic blood pressure. GCS: Glasgow Coma Scale; NIHSS: National Institutes of Health Stroke Scale; HV: hematoma volume; IVH: intraventricular hemorrhage.
