Review Meta Analysis
Small intracerebral haemorrhages are associated with less haematoma expansion and better outcomes.
Haematoma expansion following intracerebral haemorrhage is a major determinant of early neurological worsening and poor clinical outcome. This has created interest in improving patient selection for therapies targeting haematoma expansion. Based on prior observations, we hypothesised that intracerebral haemorrhage volumes under 10 ml would be less likely to expand. We additionally sought to define a baseline haematoma volume below which significant growth was not observed. ⋯ This study provides observational evidence that very small haematomas are unlikely to expand, by commonly used absolute growth definitions, and may represent a subgroup of patients with intracerebral haemorrhage destined towards good clinical outcomes.
