“…3 A common femoral vein pseudoaneurysm was also incorrectly diagnosed by MRI as haematoma resorption. 8 In the present case, the potential diagnoses described at MRI examination included superficial arterial pseudoaneurysm, AV malformation, and subcutaneous haemangioma, but not venous pseudoaneurysm. Ultrasound imaging seems to be a better tool for the diagnosis of venous pseudoaneurysms at the GSV level.…”

Traumatic venous pseudoaneurysm is extremely rare. Only two cases of great saphenous venous (GSV) pseudoaneurysm have been reported. We present a case in which a gradually enlarged mass occurred at the calf after local injury. It was nonpulsatile and varied in size with posture. It was initially misdiagnosed by contrast MRI. Duplex ultrasound and surgical intervention eventually identified it as a GSV pseudoaneurysm. This case demonstrates the need for physicians to consider venous pseudoaneurysm as a possible diagnosis for nonpulsatile masses in patient with traumatic history, and to use Duplex ultrasound for adequate evaluation.

“…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.…”

Transoral carotid ultrasonography (TOCU) is a powerful tool for evaluating internal carotid artery (ICA) lesions located from the carotid bifurcation up to the level of the second cervical vertebra. Superb‐microvascular imaging (SMI) is a new Doppler imaging technique whose algorithm analyze tissue movements to minimize motion artifacts by eliminating clutter signals. SMI significantly reduces motion artifacts and allows visualization of low‐velocity blood flow even in minute vessels. TOCU with SMI produces clear intraluminal image of the distal extracranial ICA, which is not possible with conventional carotid artery ultrasonography (CUS). CUS with SMI and TOCU with SMI were performed in a patient with a history of carotid artery stenting for symptomatic left ICA stenosis, providing images of the full length of the stents with intimal hyperplasia.

“…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].…”

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

A peritonsillar abscess is a common deep infection that is usually related to acute tonsillitis. Needle aspiration is often performed for diagnosis and treatment, but several complications, including puncture of the carotid artery, may occur, even when performed by properly trained physicians. The utility of transoral pharyngeal ultrasonography (TOPU) equipped with a biopsy adaptor for safe and full aspiration is presented. A 19-year-old man was admitted to our hospital because of a peritonsillar abscess. TOPU showed the abscess and a branch of the carotid artery, and an otolaryngologist performed puncture through the biopsy adaptor with the aid of the ultrasound image. Needle aspiration was accomplished by avoiding arterial puncture and monitoring the shrinkage of the abscess. TOPU-guided needle aspiration is useful in the safe drainage of peritonsillar abscesses.
