Abstract

Carotid web is a disease that is rarely found in patients with ischemic stroke, whereas it is more frequently observed in cryptogenic stroke patients. Fibromuscular dysplasia is known as the cause of carotid web, and it has been reported that carotid web causes blood flow disturbance, resulting in both thrombus and embolic stroke. Carotid web is confused with carotid dissection because fibromuscular dysplasia causes relatively rigid fibrous structures to grow into the lumen of the carotid artery and this creates a double lumen that is seen on duplex sonography. In addition, carotid web is web-shaped and may be confused with other carotid artery diseases such as ulcerative plaque. However, carotid web tends to be thicker at the beginning and thinner at the end, and it also has no flutter. Therefore, this study reports on four cases of carotid web with the overall description of the carotid web and the characteristic findings of duplex sonography in patients with carotid web.
