Contrast‐enhanced transoral carotid ultrasonography for the evaluation of a long stenotic lesion in the internal carotid artery

Abstract

Key Clinical MessageContrast‐enhanced transoral carotid ultrasonography (CETOCU) is a novel modality for imaging the distal extracranial internal carotid artery, which is not possible with conventional carotid ultrasonography. We present a representative case that demonstrates the usefulness of CETOCU.

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

“…[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].…”

Contrast‐enhanced transoral carotid ultrasonography for the evaluation of plaque protrusion after carotid artery stenting

“…Transoral carotid ultrasonography (TOCU) is a useful imaging modality for diagnosis of extracranial internal carotid artery (ICA) lesions . Contrast‐enhanced transoral carotid ultrasonography (CETOCU) provides a clear intraluminal image of the distal extracranial ICA that cannot be reached from the neck . We report the case of a patient with plaque protrusion after carotid artery stenting (CAS), in whom CETOCU offered clear and detailed images of the protrusion.…”
