Background: We explored the clinical significance of the residual hematoma cavity 1 year after minimally invasive intracerebral hemorrhage (ICH) evacuation.
Methods: Patients presenting with spontaneous supratentorial ICH were evaluated for minimally invasive surgical evacuation. Inclusion criteria included age ≥18 years, preoperative hematoma volume (Hv) ≥15 mL, presenting National Institutes of Health Stroke Scale score ≥6, and premorbid modified Rankin Scale (mRS) score ≤3.
