Background and purpose: Prognostic evaluations of stroke start with the onset of the disease. We analyzed the stroke outcome regarding the degree of recovery and the quality of life. Patients and methods: A group of 50 patients aged from 35-76 years was analyzed. Transcranial Doppler sonography was used to assess blood now velocity in acute stroke. All the patients were admitted within the first 24 hours after the stroke onset. Blood flow velocity (BFV) was investigated in both middle cerebral arteries (MCA), both anterior (ACA) and posterior (PCA) cerebral arteries, as well as in the carotid siphon (CS). Initial assessment was performed within the first 24 hours after the onset of the disease and compared with neurological findings. The second examination, 3 weeks after the onset of stroke, was compared with the referent values given by the laboratory for cerebrovascular diagnostics of our Department. Results and conclusion: Neurological examinations revealed hemiplegia and cranial nerve paralysis. Intracranial hemorrhage was eliminated by CT, while an extracranial occlusive disease was excluded by extracranial Doppler examinations. In all the patients CT findings were consistent with an ischemic stroke in MCA irrigation area, It has been demonstrated that those patients in whom BFV in MCA within the first 24 hours was 30cm/sec or higher had better chances for survival and suffered lesser invalidism. The patients with occluded MCA and BFV lower than 30 cm/sec in other vessels had poor prognosis. It is suggested that BFV of 30 cm/sec is a required minimum for blood perfusion.
