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

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.

The utility of superb‐microvascular imaging for evaluating the full length of carotid artery stents

“…In the present case, it was possible to evaluate the full length of long ICA stents by ultrasonography alone, without angiography. Contrast‐enhanced (with perfluorobutane microbubbles) transoral carotid ultrasonography (CETOCU) has been recently proposed to provide better intraluminal images of extracranial ICA than with CUS. In our experience, TOCU with SMI could offer images comparable to CETOCU, but this has to be confirmed by further clinical studies.…”

Utility of transoral motion‐mode ultrasonography to detect tongue fasciculation in patients with amyotrophic lateral sclerosis

“…We recently demonstrated the utility of transoral carotid ultrasonography using a transvaginal probe 7‐10 to evaluate involuntary movements of the tongue in patients with palatal tremor, and we called this method “transoral motion‐mode ultrasonography” (TOMU) 11 . Because TOMU enables direct contact of the probe with the tongue, providing an image with a large field of view, we hypothesized that this method would be useful for the assessment of tongue fasciculations in patients with ALS.…”

“…[3][4][5][6] As methods to evaluate tongue fasciculations by ultrasonography, the submandibular approach and the transoral approach using a "hockey-stick" probe have been reported to improve the sensitivity of ALS diagnosis. 3,5 We recently demonstrated the utility of transoral carotid ultrasonography using a transvaginal probe [7][8][9][10] to evaluate involuntary movements of the tongue in patients with palatal tremor, and we called this method "transoral motion-mode ultrasonography" (TOMU). 11 Because TOMU enables direct contact of the probe with the tongue, providing an image with a large field of view, we hypothesized that this method would be useful for the assessment of tongue fasciculations in patients with ALS.…”

Ultrasound-Guided Needle Aspiration of Peritonsillar Abscesses: Utility of Transoral Pharyngeal Ultrasonography

“…Transoral ultrasonography is a well-known technique for examining the carotid artery [1][2][3][4], known as "transoral carotid ultrasonography" (TOCU). Transoral ultrasonography is also useful in the field of otolaryngology, in addition to angiology [5][6][7].…”
