Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre-/peri-interventional assessment of CAD patients who undergo carotid revascularization procedures...

Patients with critical limb ischemia necessitate immediate intervention to restore blood flow to the affected limb. Endovascular procedures are currently preferred for these patients. We describe the case of an 80-year-old female patient who presented to our department with ischemic rest pain and ulceration of the left limb. The patient had history of left femoral popliteal bypass surgery, femoral thromboendarterectomy and patch angioplasty of the same limb 2 years ago. Doppler sonography and magnetic resonance angiography revealed an occlusion of the left superficial femoral artery (SFA) and popliteal artery and of all three infra-popliteal arteries...

With the development of assisted reproductive technology and the ethical limitations of research on humans, rat animal models have been widely used in reproductive medicine. In the past, the study of reproductive system development in rodents has been based on one-time histological examination of excised tissues. Recently, with the development of high-resolution transabdominal ultrasound, high-quality sonography can now be performed to evaluate the reproductive organs of rats, allowing a new method for studying the reproductive system...

Recent technical advances in neurosonography continue broadening the diagnostic utility, sensitivity, and specificity of ultrasound for detecting intracranial abnormalities bed side. The clinical and functional applications of neurosonography have significantly expanded since the 1980s when transcranial Doppler sonography first allowed anatomic and hemodynamic delineation of the intracranial vessels through the thin temporal skull. In the past few years, contrast-enhanced ultrasonography, elastography, 3D/4D reconstruction tools, and high-resolution microvessel imaging techniques have further enhanced the diagnostic significance of neurosonography...

BACKGROUND: The noninvasive encapsulated follicular variant of papillary carcinoma (nEFVPTC) has recently been reclassified to "noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)," removing this entity from the malignant category. This re-categorization has had major implications for clinical management. NIFTP has overlapping cytohistologic features with papillary thyroid carcinoma (PTC) and with follicular adenomas (FA), but sonographic data comparing NIFTP to PTC and FA is lacking...

BACKGROUND: Behçet's disease (BD) is a chronic autoimmune disorder with symptoms manifesting from an underlying vasculitis. Since the disease activity is correlated with the characteristic vascular endothelial dysfunction, BD places individuals at increased risk of cardiovascular diseases, such as atherosclerosis. Hyperhomocysteinemia is an independent risk factor for arteriosclerotic vascular diseases. This study was designed to investigate how plasma homocysteine (Hcy) effects the structural and functional properties of the carotid artery in humans...

Giant Cell Arteritis (GCA) and Takayasu's arteritis (TA) are large vessel vasculitis (LVV) primarily affecting the aorta and its major branches, mainly differentiated by the onset age (>50 years GCA and <40 years TA). In addition, temporal artery involvement and polymyalgia rheumatic are typical features of GCA, but not TA. Imaging techniques are required to secure the diagnosis of large-vessel vasculitides, and to monitor the disease course. Both morphological and metabolic imaging are involved. Morphological imaging is represented mainly by Computerized Tomography (CT), CT angiography, Magnetic Resonance (MR), MR angiography, Color-Doppler Sonography (CDS) and high-resolution CDS...

Sonography is conventionally used to diagnose fractures by identifying cortical discontinuity of the bone. In this study, fracture sonography in addition to color Doppler and dynamic scanning was performed in settings with limited or no access to radiography. We describe 5 cases of ankle and foot fractures with the use of sonography to identify changes in the fractured site. The width of the fracture space increased on dynamic scanning, and the Doppler signals were generated inside the fracture space on dynamic scanning...

BACKGROUND Round ligament varices (RLV) are rare and are almost exclusively seen in pregnant women. RLV may clinically resemble an inguinal hernia, inguinal mass, or other pathology involving the inguinal canal and round ligament. Ultrasound imaging is important to make the diagnosis of RLV. CASE REPORT A 34-year-old Hispanic woman, gravida 1 para 0, at 34 weeks gestation, presented to our outpatient department with a complaint of a small, painless, reducible right inguinal mass. Gray-scale sonography showed an asymmetric right inguinal anechoic mass composed of multiple serpentine tubular channels, which became more prominent when the patient performed a Valsalva maneuver...

The zygomatico-orbital artery is the largest artery in the temporal area. With the increasing number of reconstructive and aesthetic surgeries in the area, in-depth understanding of this artery is needed. Thus, the aim of this anatomical study was to determine more information on the zygomatico-orbital artery using contrast-enhanced three-dimensional computer tomography (CT) and color-flow Doppler sonography. On the basis of CT images taken between October 2015 and October 2016 for diagnosing and treating maxillofacial conditions, 50 patients were selected...

OBJECTIVES: Cochlear implantation (CI) has been the most successful procedure for restoring hearing in a patient with severe and profound hearing loss. However, possibly owing to the variable brain functions of each patient, its performance and the associated patient satisfaction are widely variable. The authors hypothesize that peripheral and cerebral circulation can be assessed by noninvasive and globally available methods, yielding superior presurgical predictive factors of the performance of CI in adult patients with postlingual hearing loss who are scheduled to undergo CI...

Ultrasound imaging may have an impact in management patients with rheumatoid arthritis. Through technological improvements, ultrasonography, has become an established imaging technique for the diagnosis and the follow up of this inflammatory chronic disease. In fact, ultrasounds, allow follow up during treatment by evaluating synovitis count and assessment of synovial vascularization by Power Doppler. Besides, erosions are found sooner and more frequently by ultrasonography than with conventional radiography...

PURPOSE AND HYPOTHESIS: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory. The hypothesis that contrast-enhanced ultrasound (CEUS) could detect with more sensibility than PD the new vessel ingrowth in human degenerated Achilles tendons and therefore the correlation of neovascularization with pain and disability, was evaluated...
