Abstract

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.

RESULTS: Of the 110 patients, hemorrhagic transformation occurred in 59 patients, including 7 PH. In univariate analysis, the acute National Institutes of Health Stroke Scale score (P=0.002), acute diffusion-weighted imaging lesion volume (P=0.02), and thrombolysis (P=0.03), but not very low CBV (P=0.52), were associated with hemorrhagic transformation. The volume of very low CBV was the only predictor of PH (P=0.007). Early reperfusion and recanalization had no influence on either hemorrhagic transformation or PH.

CONCLUSION: Very low CBV was the only independent predictor of PH in patients with acute stroke.
