Transcranial Doppler evaluation of arterial occlusive disease in aphasic patients

Background and purpose Aphasia is a sign of cortical in- volvement in stroke patients, affecting the dominant hemis- phere supplied by the middle cerebral artery (MCA). The diag- nose ofMCA occlusion is connected with transport to radiology. In order to evaluate the localization of arterial occlusive di- sease, we evaluated acute aphasic stroke patients by means of transcranial Doppler (TCD). Patients and methods We investigated 30 ischemic stroke pa- tients admitted within 24 hours from stroke onset. All patients were right handed, except one, and fulfilled the criteria for aphasia according to the Boston Diagnostic Examination of Aphasia. TCD was performed bedside with DWL Multi Dop XL, 2 MHz transducer. Thrombolysis in brain ischemia (TIBI) criteria was applied for localization of the MCA occlusion. Results Out of 30 patients, 6 had left Ml MCA occlusion, one right Ml MCA occlusion, 4 left Ml MCA stenosis, and 6 left M2 or M3 occlusion, and 9 hypo-perfusion. Early ischemic signs in left MCA territory were visible in 27 patients. 9 pa- tients had left internal carotid artery (ICA) subtotal stenosis (3 intracranial, 6 extracranial), and 7 left ICA occlusion (1 intracranial, 6 extracranial) and one right ICA occlusion. Conclusion TCD is a useful and non-invasive method for bedside evaluation of MCA occlusive disease in acute stroke patients with aphasia.
