Contrast-enhanced transoral carotid ultrasonography for the diagnosis and follow-up of extracranial internal carotid artery dissection: A case report

J Clin Ultrasound. 2018 Jun;46(5):368-371. doi: 10.1002/jcu.22542. Epub 2017 Oct 9.

Abstract

A 56-year-old woman was admitted to our hospital because of amaurosis fugax. The carotid angiogram showed irregularly stenotic lesions of the left and right internal carotid arteries (ICAs), suggestive of dissection. Follow-up evaluation was performed by transoral carotid ultrasonography (TOCU) with contrast enhancement (CE), which yielded better vessel lumen and intramural hematoma visualization than color Doppler imaging. CE-TOCU is useful for evaluating ICA dissections that extends to the high cervical portion.

Keywords: carotid artery; contrast-enhanced ultrasonography; dissection; transoral examination.
