Abstract

Introduction. The volume of cerebral hemorrhage in patients with hemorrhagic stroke influences intracranial pressure, blood flow, clinical state and prognosis.
Aim of study. Evaluation of blood flow in middle cerebral arteries and level of brainstem insufficiency related to cerebral hemorrhage volume in patients with supratentorial brain hemorrhage.
Material and methods. We studied 56 patients hospitalized within the first 24 hours of stroke onset. On the ground of computer tomography (CT), using planimetric method, the volume of cerebral hemorrhage was assessed. Transcranial Doppler sonography (TCD) was used to measure pulsatility index (Pi) and mean flow velocity (Vś) in middle cerebral artery on the cerebral hemorrhage side (Pik, Vśk) and opposite side (Pip, Vśp). The level of brainsteam insufficiency was evaluated with brainsteam insufficiency scale (ITC scale).
Results. Higher Pi and lower Vś on cerebral hemorrhage side were found in 47 patients (83.9%). The asymmetry of these parameters were correlated with cerebral hemorrhage volume (Pi, p < 0.001; Vś, p < 0.001). In the group of patients with cerebral hemorrhage volume 25-50 mL, on cerebral hemorrhage side, higher mean values of Pi (p < 0.05) and lower of Vś were found, comparing to the group with cerebral hemorrhage < 25 mL. In the group of patients with cerebral hemorrhage > 50 mL, the mean Pi values were higher (Pik, p < 0.001; Pip, p < 0.05), while Vś lower (Vśk p < 0.001; Vśp p < 0.05) on both sides, comparing to group with cerebral hemorrhage < 25 mL. Scale of ITC scoring was correlated with presence of cerebral hemorrhage (p < 0.001).
Conclusion. 1. In patients with hemorrhagic stroke blood flow in middle cerebral artery on the cerebral hemorrhage side was lower than on the opposite side. 2. Asymmetry of blood flow correlated with cerebral hemorrhage volume. 3. Blood flow in both middle cerebral arteries was lower in patients with cerebral hemorrhage > 50 mL than in patients with cerebral hemorrhage < 50 mL. 4. Clinical state of the patients correlated with cerebral hemorrhage volume.
