INTRODUCTION: Although grayscale ultrasound and color Doppler ultrasound characteristics of the torsed testis are well established in the literature, less is known about its anatomic partner: the epididymis. OBJECTIVE: The purpose of this study was to describe the ultrasound characteristics of the epididymis in pediatric patients with testicular torsion, and to describe their potential role as prognostic criteria for testicular salvage outcomes. STUDY DESIGN: During a retrospective review of 217 pediatric patients with acute testicular torsion during 2009-2016, morphological features of the epididymis from scrotal ultrasounds (size, parenchymal characteristics, and vascular flow of both epididymis heads), as well as patient demographics, time duration, surgical outcomes, histopathology results, and follow-up periods were analyzed...

BACKGROUND: Recent findings on the pathogenesis of frontal migraine headache support, besides a central vasogenic cause, an alternative peripheral mechanism involving compressed craniofacial nerves. This is further supported by the efficiency of botulinum toxin injections as a new treatment option in frontal migraine headache patients. METHODS: The supraorbital regions of 22 alcohol-glycerine-embalmed facial halves of both sexes were dissected. Both the supratrochlear and supraorbital nerves (STN and SON, respectively) were identified, and their relationship with the corrugator supercilii muscle (CSM) was investigated by dissection and ultrasound...

OBJECTIVE: Prior studies have suggested a relationship between operative (Op) time and outcome after major vascular procedures. This study analyzed factors associated with Op time and outcome after carotid endarterectomy (CEA) in the Vascular Quality Initiative (VQI) registry. METHODS: Elective, primary CEAs without high anatomic risk or concomitant procedures from 2012 to 2015 in the VQI were analyzed (N = 26,327, performed by 1188 surgeons from 249 centers). Multivariable analysis was used to identify patient, procedure, and surgeon factors associated with Op time and major adverse events (MAEs), categorized as either technical (ipsilateral stroke, cranial nerve injury, reoperation) or cardiac (myocardial infarction, congestive heart failure, dysrhythmia requiring treatment, surgical site infection, and death)...

Features of high-risk coronary artery plaques prone to major adverse cardiac events (MACE) were identified by intravascular ultrasound (IVUS) virtual histology (VH). These plaque features are: Thin-cap fibroatheroma (TCFA), plaque burden PB≥70%, or minimal luminal area MLA≤4mm². Identification of arterial locations likely to later develop such high-risk plaques may help prevent MACE. We report a machine learning method for prediction of future high-risk coronary plaque locations and types in patients under statin therapy...

In pigs, the deep location of the common carotid artery and overlying sternomastoideus muscle in the neck has led to the recommendation for a surgical cutdown for common carotid access, as opposed to minimally invasive techniques for vascular access. We sought to determine if direct percutaneous common carotid artery access in piglets is attainable. Seventeen piglets were anesthetized and intubated. Under two-dimensional and color flow Doppler ultrasound guidance, a 21 gauge needle was utilized to access the right common carotid artery...

This review examines four imaging modalities; ultrasound (US), digital subtraction angiography (DSA), magnetic resonance imaging (MRI) and computed tomography (CT), that have common or potential applications in vascular access (VA). The four modalities are reviewed under their primary uses, techniques, advantages and disadvantages, and future directions that are specific to VA. Currently, US is the most commonly used modality in VA because it is cheaper (relative to other modalities), accessible, non-ionising, and does not require the use of contrast agents...

A 54 year-old healthy woman presented to the emergency department with a right sided facial paralysis. About 3 weeks ago, she woke up and noticed an attached engorged tick in her right lower extremity. A week later, she noticed a mild to moderate right jaw pain which progressed to a severe right facial pain so she visited her doctor. On physical, II to XII cranial nerve examination was unremarkable. Doppler ultrasound did not show any vascular abnormalities in temporal artery. Her inflammatory markers were within normal limits (C-reactive protein:0...

Vascular deficiencies and reduced perfusion of the anterior tibial artery and the dorsalis pedis artery were suggested as causes of congenital talipes equino varus (CTEV). In this study, we assessed the prevalence of arterial abnormalities in patients with CTEV (50 patients; 74 feet) compared with a normal control group (16 patients; 32 feet) by Doppler ultrasound and Ankle Brachial Index. The flow was normal in the control group and was deficient in 39.19% of clubfoot patients. In severe clubfoot cases, the deficiency was found to an extent of 76...
