Middle cerebral artery dissection: diagnostic and prognostic value of transcranial color-coded sonography

We report 2 patients with ischemic stroke related to an initial severe focal narrowed middle cerebral artery caused by a dissection mechanism, a presentation that has received little attention to date. Diagnostic modalities and follow-up using transcranial color-coded sonography are reported and discussed. Results with transcranial color-coded sonography were correlated with computed tomographic angiography, showing the great value of this radiation-free arterial monitoring process in this setting, especially in young adults.
