Mobility of an in-stent plaque protrusion detected with carotid duplex during the carotid artery stenting procedure: a case report.

Med Ultrason 2019 Feb;21(1):89-92

Department of Neurosurgery and Stroke Center, Tenri Hospital, Tenri, Japan.

In-stent plaque protrusion (ISP) is a predictor for ischemic complications in carotid artery stenting (CAS). Because its mobility would further increase the distal embolization risk, the intraprocedural detection of mobility is important but has not yet been reported. We present an 87-year-old male with symptomatic right carotid artery stenosis who underwent CAS. Read More

Traumatic Injury of the Petrous Part of the Temporal Bone: Keys for Reporting a Complex Diagnosis.

Radiologia 2019 Feb 15. Epub 2019 Feb 15.

Departamento de Radiología, Hospital Universitario La Paz, Madrid, España.

Fractures of the petrous part of the temporal bone are a common lesion of the base of the skull; most of these fractures result from high-energy trauma. In patients with multiple trauma, these injuries can be detected on CT scans of the head and neck, where the direct and indirect signs are usually sufficient to establish the diagnosis. It is important to these fractures because the temporal bone has critical structures and the complexity of this region increases the risk of error unless special care is taken. Read More

Ultrasound Evaluation of Transient Ischemic Attack Caused by Styloid Process Elongation: A Case Report.

Front Neurol 2019 29;10:26. Epub 2019 Jan 29.

Department of Vascular Ultrasonography, Xuanwu Hospital, Capital Medical University, Beijing, China.

Stylocarotid artery syndrome (SAS) is a type of Eagle syndrome, which is caused by the compression of the internal or external carotid artery (along with their perivascular sympathetic fibers) by an elongated styloid process, resulting in neurological symptoms including transient ischemic attack (TIA) and cervicofacial pain along the distribution of the artery. The authors describe the case of a 56-year-old man with a history of TIA of unknown origin, who underwent color Doppler flow imaging (CDFI) that detected an elongated styloid process and transcranial Doppler (TCD) monitoring that revealed changes in intracranial blood flow when turning his head. To the best of our knowledge, this report is the first to describe the combination of CDFI and TCD to assess changes in extracranial and intracranial blood flow in patients with suspected SAS.

Three-Dimensional Echographic Evaluation of Carotid Artery Disease.

J Cardiovasc Echogr 2018 Oct-Dec;28(4):218-227

Department of Translational Research and New Technologies in Medicine and Surgery, Pisa University, Pisa, Italy.

The introduction of three-dimensional echography (3D echo) in vascular field is not recent, but it still remains a seldom-used technique because of the costs of ultrasound probe and the need of dedicated laboratories. Therefore, despite significant prognostic implications, the high diagnostic accuracy in plaque definition, and the relative ease of use, 3D echo in vascular field is a niche technique. The purpose of this review is mainly clinical and intends to demonstrate the potential strength of a 3D approach, including technical aspects, in order to present to clinicians and imagers the appealing aspects of a noninvasive and radiation-free methodology with relevant diagnostic and prognostic correlates in the assessment of carotid atherosclerosis.

Persistent Target Mismatch Profile >24 Hours After Stroke Onset in DEFUSE 3.

Stroke 2019 Feb 8:STROKEAHA118023392. Epub 2019 Feb 8.

From the Stanford Stroke Center, Stanford University School of Medicine, CA (S.C., M.M., S.K., A.Y., M.G.L., G.W.A.).

Background and Purpose- Efficacy of endovascular thrombectomy has been demonstrated up to 24 hours after stroke onset in patients selected with perfusion imaging. We hypothesized that a persistent favorable perfusion profile exists in some patients beyond 24 hours from the onset and can be predicted by a lower baseline hypoperfusion intensity ratio, which indicates favorable collaterals. Methods- We identified control arm patients from the DEFUSE 3 trial (The Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke) with a diffusion weighted imaging and perfusion magnetic resonance imaging performed 24 hours following randomization and compared imaging and clinical variables between patients with persistent mismatch versus patients who no longer had a mismatch 24 hours after randomization.

The influence of sleep apnea syndrome and intermittent hypoxia in carotid adventitial vasa vasorum.

PLoS One 2019 5;14(2):e0211742. Epub 2019 Feb 5.

Endocrinology and Nutrition Department, University Hospital Arnau de Vilanova, Obesity, Diabetes and Metabolism (ODIM) research group, IRBLleida, University of Lleida, Lleida, Catalonia, Spain.

Subjects with sleep apnea-hypopnea syndrome (SAHS) show an increased carotid intima-media thickness. However, no data exist about earlier markers of atheromatous disease, such as the proliferation and expansion of the adventitial vasa vasorum (VV) to the avascular intima in this setting. Our aim was to assess carotid VV density and its relationship with sleep parameters in a cohort of obese patients without prior vascular events. Read More

Non-invasive Small Vessel Imaging of Human Thyroid Using Motion-Corrected Spatiotemporal Clutter Filtering.

Ultrasound Med Biol 2019 Feb 2. Epub 2019 Feb 2.

Department of Radiology, Mayo Clinic College of Medicine and Science, Rochester, Minnesota, USA. Electronic address:

Reliable assessment of small vessel blood flow in the thyroid, without using any contrast agents, can be challenging because of increased physiological motion resulting from its proximity to the pulsating carotid artery. In this study, we hypothesized that correction of tissue motion prior to singular value decomposition (SVD)-based clutter filtering can improve the coherency of the tissue components and, thus, may allow better clutter suppression and visualization of small vessels in the thyroid. We corroborated this hypothesis by conducting phantom and in vivo studies using a clinical ultrasound scanner implemented with compounded plane wave imaging. Read More

Effect of insonation angle on peak systolic velocity variation.

Am J Emerg Med 2019 Jan 29. Epub 2019 Jan 29.

Olive View-UCLA Medical Center, United States of America. Electronic address:

Objectives: As point of care ultrasound (POCUS) has become more integrated into emergency and critical care medicine, there has been increased interest in utilizing ultrasound to assess volume status. However, recent studies of carotid POCUS on volume status and fluid responsiveness fail to recognize the effect insonation angle has on their results. To address this, we studied the effect of insonation angle on peak systolic velocity (PSV) change associated with respiratory variation (RV) and passive leg raise (PLR). Read More
