Background: Whether minimally invasive endoscopic surgery (ES) improves survival and functional outcome in people with spontaneous supratentorial intracerebral hemorrhage (SSICH) is unknown.
Methods: This is a single-center pilot study performed between July 2021 to January 2023. Any supratentorial hematoma with a volume between 20 mL and 100 mL was endoscopically evacuated within 24 h after bleeding onset.
