Very Low Cerebral Blood Volume Predicts Parenchymal Hematoma in Acute Ischemic Stroke

AHA – May 30, 2013

Background and Purpose—Parenchymal hematoma (PH) may worsen the outcome of patients with stroke. The aim of our study was to confirm the relationship between the volume of very low cerebral blood volume (CBV) and PH using a European multicenter database (I-KNOW). A secondary objective was to explore the impact of early reperfusion and recanalization.

Methods—The volume of cerebral tissue with CBV ≤2.5th percentile of the normal hemisphere was calculated within the acute diffusion-weighted imaging lesion. Hemorrhagic transformation was assessed on day 2 MRI according to the European Cooperative Acute Stroke Study II criteria. Recanalization and reperfusion were assessed on 3-hour follow-up MRI.
