Investigations of patient with TIA's

ABSTRACT

Transient ischemic attacks [TIAs] result from large or small vessel disease, cardiogenic embolic events or hematological abnormalities. Every patient presenting with a TIA should have total blood count, electrocardiogram, and a brain imaging study. Noninvasive carotid testing, usually by carotid duplex ultrasonography, magnetic resonance angiography [MRA] or a conventional arteriogram may be required. In general, a TIA should be considered as a warning of impending stroke that requires rapid and efficient investigations to define and remedy the reasons for the cerebral ischemic events
