Abstract
Ultrasound is a tool that is widely used in medicine in different areas such as gynecology or surgery. In neurology, it has a broad variety of indications, related to the study of vasospasm and subarachnoid haemorrhage, besides of flux changes in intracranial stenosis and it helps to evaluate the activity of some therapeutic measures. In this article we present some of the most relevant cases collected in the Hospital Universitario Mayor, wich were taken to a trans cranial duplex and we provide a short revision about most frequent pathologic that can be found through this study. The transcranial duplex offers a diagnose possibility of fast evaluation that takes reliable information to make choices in the emergency room as in the hospitalized. Although this procedure does not have many experience in the country, it is important to mention that these findings turn out to be an innovating solution to a quick diagnose that should be complemented with further information.
