OBJECTIVE: Asymptomatic internal carotid artery occlusion (CO) presents a clinical dilemma, and presently, the natural history, stroke risk, and optimal management remain ill defined. This study compared outcomes, including neurovascular events (NVEs) and health care costs, between patients with CO and patients with asymptomatic carotid artery stenosis (CS). METHODS: A prospectively maintained database was queried to identify patients with CO and CS with at least >50% carotid stenosis by duplex...

Peripheral artery disease (PAD) is the most frequent cause for reduced perfusion in peripheral arteries. Patients with PAD have often manifestations of atherosclerosis in other vascular territories. Typical symptoms are intermittent claudication or rest pain and acral lesions in patients with critical limb ischemia. The majority of PAD patients are clinically asymptomatic; therefore, it makes sense to screen for PAD in patients with cardiovascular risk factors. The ankle brachial index (ABI) is regarded as an easy and cost-effective method for baseline diagnostics...

Thoracic Outlet Syndrome (TOS) describes a set of disorders that arise from compression of the neurovascular structures that exit the thorax and enter the upper extremity. This can present as one of three subtypes: neurogenic, venous, or arterial. The objective of this section is to outline our current practice at a single, high-volume institution for venous and arterial TOS. VTOS: Patients who present within two weeks of acute deep vein thrombosis (DVT) are treated with anticoagulation, venography, and thrombolysis...

Atherosclerosis is a systemic disease with manifestations in multiple vascular beds. Ideal cardiovascular health (CVH) metrics relate to cardiovascular and cerebrovascular disease. However, the relation between ideal CVH metrics and asymptomatic polyvascular disease (polyVD) is unknown. We collected information on the 7 CVH metrics among 5,224 participants aged ≥40 years from 2010 to 2011. Intracranial artery stenosis, extracranial artery stenosis, and lower extremity artery disease were detected by transcranial Doppler, duplex sonography, and by calculating ankle-brachial index...

Sensitive detection of a low abundant protein is essential for biomedical research and clinical diagnostics. Herein, we develop a label-free colorimetric biosensor for the sensitive detection of recombinant human vascular endothelial growth factor-165 (VEGF165). This biosensor consists of an aptamer-based hairpin probe, an assistant DNA-trigger duplex and a linear template. In the presence of VEGF165, the specific binding of VEGF165 with the aptamer-based hairpin probe results in the opening of a hairpin probe and the opened hairpin probe subsequently hybridizes with the single-stranded region of the assistant DNA-trigger duplex to initiate the strand displacement amplification (SDA) to yield abundant triggers...

INTRODUCTION: Deep wound infections in the groin region can result in an acute or life threatening condition. Especially when there is no suitable vein available because of many reasons (e.g. previous surgery, small vessel diameter). Synthetic prosthesis sometimes are not 'first-choice-technique' because of contamination or infection. It was ad hoc hypothesized in an acute setting that a segment of an occluded Superficial Femoral Artery (SFA) could be used as a conduit in combination with eversion technique, known from carotid surgery...

Jugular vein aneurysms are rare vascular abnormalities that are most commonly encountered in the pediatric population. We report two separate cases in infants, both of whom presented with enlarging neck masses and were found to have jugular vein aneurysms. Diagnosis was established with duplex ultrasonography, computed tomography angiography, digitally subtracted catheter venography, and magnetic resonance imaging in one case and magnetic resonance imaging with magnetic resonance angiography/magnetic resonance venography, gray scale ultrasonography, and digital subtraction catheter venography in the other case...

BACKGROUND: Pink pulseless hand syndrome is a rare condition of vascular injury due to distal humerus fracture. It is characterized by radial and ulnar pulselessness in a complex of good hand perfusion which can remain pink and warm. The management and treatment of this condition is still very debated. METHODS: We report four cases of arm traumas which occurred in pediatric patients. In all cases, after the fixation of the fracture by the orthopedic surgeon, the clinical evaluation and duplex ultrasound demonstrated the so called "pink pulseless hand syndrome"...
