Separate Spontaneous Extracranial and Intracranial Left Internal Carotid Artery Dissections Causing an Acute Ischemic Stroke: A Case Report.

We present a case of a 45-year-old man who suffered simultaneous intracranial and extracranial dissections within the same artery, ultimately leading to a large left-sided ischemic stroke. To our knowledge, this is the only reported case of multiple dissections of the same head or neck (cervicocephalic) artery. We discuss the current evidence and literature around the characteristics of patients who experience multiple cervicocephalic artery dissections.
