Early and effective intracerebral hemorrhage evacuation is associated with a lower 1-year residual cavity volume and better functional outcomes.

After minimally invasive ICH evacuation the hematoma lesion decompresses significantly, with a residual Cv just 5% of the original lesion, but then gradually increases in size over time. Early and high percentage ICH evacuation may reduce the remnant Cv over time which, in turn, is associated with improved functional outcomes.
