Web Browsing: High-Speed Diagnosis and Treatment of Carotid Artery Web.

Although carotid artery web (CaW) was initially described in 1973 as a potential etiology of ischemic stroke, it still remains underrecognized. Because CaW is a membrane affixed perpendicularly from the carotid wall that projects out into the lumen above the bifurcation, it typically is not stenotic, and hence, utilizing only 1 vessel imaging modality during conventional stroke workup may instead lead to a diagnosis of ESUS: embolic stroke of undetermined source. The term ESUS was created in 2014 by researchers to define a subset of cryptogenic, nonlacunar (embolic-appearing) strokes without clear cardiac or vascular cause.
