A 43-day-old boy presented with bacteremia after umbilical artery catheterization. Duplex ultrasound examination revealed a 1.1- × 1.6-cm mycotic infrarenal aortic aneurysm and an incidental asymptomatic occluded right common iliac artery. Resection and repair were completed by creating an everted, double-layered internal jugular vein patch. Screening ultrasound examination 10 months postoperatively demonstrated successful repair.

Conventional diagnostic modalities for assessing arterial circulation or tissue perfusion include blood pressure measurement, ultrasound evaluation, and contrast-based angiographic assessment. An infrared thermal camera can detect infrared radiation energy from the human body, which generates a thermographic image to allow tissue perfusion analysis. We describe a smartphone-based miniature thermal imaging system that can be used as an adjunctive imaging modality to assess tissue perfusion. This smartphone-based camera device is noninvasive, simple to use, and cost-effective in assessing patients with lower extremity tissue perfusion...

Vasculitis is a clinical condition with associated diagnostic challenges due to nonspecific symptoms and lack of a confirmatory imaging modality. We report a case of a 39-year-old female patient who developed generalized malaise, lethargy, and headache. Laboratory evaluation showed elevated inflammatory markers. Conventional imaging studies including computed tomography and carotid duplex ultrasound were unremarkable. Infrared thermography revealed enhanced thermographic signals in the left carotid artery and aortic arch...

PURPOSE OF REVIEW: Atherosclerosis has major morbidity and mortality implications globally. While it has often been considered an irreversible degenerative process, recent evidence provides compelling proof that atherosclerosis can be reversed. Plaque regression is however difficult to appraise and quantify, with competing diagnostic methods available. Given the potential of evidence synthesis to provide clinical guidance, we aimed to review recent meta-analyses on diagnostic methods for atherosclerotic plaque regression...

A 75-year-old hypertensive female with stable idiopathic intermediate uveitis presented with bilateral sequential optic neuropathy with optic disc swelling. The optic neuropathy in the first affected eye (right) was thought to be due to non-arteritic anterior ischaemic optic neuropathy (NAION). Asymptomatic left optic disc swelling was found at routine review 2 months later, and a diagnosis of giant cell arteritis (GCA) was sought. Temporal artery duplex ultrasound showed the "halo sign," but a subsequent temporal artery biopsy showed light-chain (AL) amyloidosis with no signs of giant cell arteritis...

REVIEW
Jaber Mustafa, Ilan Asher, Zev Sthoeger
Upper extremity deep vein thrombosis (UEDVT) is defined as thrombosis of the deep venous system (subclavian, axillary, brachial, ulnar, and radial veins), which drains the upper extremities. It can be caused by thoracic outlet anatomic obstruction, such as Paget-Schroetter syndrome, (primary) or by central intravenous catheters (secondary). UEDVT may be asymptomatic or present with acute severe pain and arm swelling. Clinical suspicion should be confirmed by diagnostic imaging procedures such as duplex ultrasound, computed tomography scan, or magnetic resonance imaging...

BACKGROUND: The main indication for carotid endarterectomy (CEA) is severity of carotid artery stenosis, even though most strokes in carotid disease are embolic. The relationship between carotid plaque volume (CPV) and symptoms of cerebral ischaemia, and the measurement of CPV by minimally invasive tomographic ultrasound imaging, were investigated. METHODS: The volume of the endarterectomy specimen was measured using a validated saline suspension technique in patients undergoing CEA...

Vascular assessment of the lower extremity is a critical step in any patient presenting with lower extremity chronic wounds to predict the likelihood of healing and risk of amputation. This concept is vital in patients with diabetes due to their complex vascular anatomy and disease distribution. Three arteries supply the six angiosomes of the lower extremity (i.e., three-dimensional blocks of tissue fed by a "source" artery in the foot and ankle). In diabetic patients, assessment of adequate blood flow to the lower extremities is complicated by the presence of arterial calcification, associated neuropathy, and inflammation...

BACKGROUND: The role of nonobstructive (<50% stenosis) carotid atherosclerosis (NOCA) in young adults with ischemic stroke is not well understood. In the present study, we investigated the prevalence and the ultrasonic characteristics of NOCA in a consecutive series of young adults with cryptogenic stroke (CS). METHODS: Patients aged 18-54, consecutively treated in a tertiary hospital for first-ever CS (defined as an ischemic stroke without ASCOD (A: atherosclerosis; S: small-vessel disease; C: cardiac pathology; O: other causes) grade 1 potential cause) in the carotid artery territory, were prospectively enrolled...

BACKGROUND: We sought to investigate the rate of radial artery occlusion (RAO) after same-day dual radial artery puncture. The trans-radial arterial approach (TRA) for diagnostic and interventional procedures has risen significantly in the United States. Although becoming more commonly performed, TRA is not without risk, and a potential complication is RAO. The rate of RAO after same-day dual artery puncture is unknown. METHODS: A retrospective analysis of 27 patients who underwent same-day dual radial artery puncture for percutaneous coronary intervention (PCI) at our institution (Providence Heart Institute in Southfield, MI, USA) from November 2011 to December 2013 were included after initially presenting for cardiac catheterization at a non-PCI-capable facility...

Pelvic kidney is a relatively common renal malformation as well as duplex kidney; however, the unilateral coexistence of these abnormalities is not frequently found. We present a case of a young woman with a history of hypertension in whom a pelvic and dysmorphic left kidney was discovered during ultrasound examination performed for the study of the renal arteries. Magnetic resonance imaging and computed tomography imaging revealed a duplex pelvic kidney. This combination is very rare; we have not found a similar case reported in the literature...

We evaluated the role of vertebral artery extracranial color-coded duplex sonography (VAECCS) in predicting vertebrobasilar stroke in consecutive patients presenting to the emergency department with vertigo of suspected ischemic origin. The final diagnosis was established by a panel of experts consisting of an emergency physician, a neurologist, and an otoneurologist. Vertebrobasilar stroke was diagnosed when an acute brain ischemic lesion congruent with symptoms was detected by neuroimaging during the index visit or a stroke was diagnosed within a 3-mo period after emergency department presentation...
