Location-Specific Analysis of Hematoma Expansion in Intracerebral Hemorrhage.

ABSTRACT:

Background

Hematoma expansion (HE) is a potential modifier of intracerebral hemorrhage (ICH) outcome, yet reducing HE does not necessarily improve prognosis. This may reflect the complex relationship between location, baseline volume, HE, and outcomes, where different locations have varying hematoma growth and differing impacts on prognosis. Prior HE studies have oversimplified location categorization into lobar and deep. Therefore, we aim to investigate how HE varies across more specific location categorization and examine their interactions.

Methods

We retrospectively analyzed 691 nonanticoagulated patients with spontaneous ICH from the University of Hong Kong ICH registry (2011-2022) and 3 regional hospitals (2020-2022). Locations were categorized into lobar, putamen/exte
