BACKGROUND: Due to the high incidence of thromboembolic events (deep venous thrombosis [DVT] and pulmonary embolus [PE]) after injury, many trauma centers perform lower extremity surveillance duplex ultrasounds. We hypothesize that trauma patients are at a higher risk of upper extremity DVTs (UEDVTs) than lower extremity DVTs (LEDVTs), and therefore, all extremities should be evaluated. MATERIALS AND METHODS: A retrospective chart and trauma registry review of Intensive Care Unit trauma patients with upper and LEDVTs detected on surveillance duplex ultrasound from January 2010 to December 2014 was carried out...

INTRODUCTION: Iatrogenic femoral artery trauma complicates the course of critically-ill neonates and children. Complications from persistent arterial occlusion include claudication and limb length discrepancies. Data supporting risk factors for such and need for revascularization are lacking. METHODS: Review of a prospectively maintained database at a tertiary institution of iatrogenic pediatric femoral artery injuries incurred between 2013-2014 was performed. Additional injuries were identified by review of pediatric arterial duplex performed between 2008-2013...

Cronobacter sakazakii and Cronobacter malonaticus are the most common species of Cronobacter , so it is necessary to detect the two species as soon as possible in surveillance programs. We developed a real-time PCR method for identifying C. sakazakii and C. malonaticus from the genus Cronobacter . In this study, the two pairs of primers and probes were designed, targeting 16S rRNA and fusA, respectively. The specificity of the real-time PCR assay was validated with 112 strains of Cronobacter , including 56 C...

BACKGROUND: Interventions for aortic aneurysm sac growth have been reported across multiple time points after endovascular aortic aneurysm repair (EVAR). We report the long-term outcomes of patients after EVAR monitored with duplex ultrasound (DUS) imaging with respect to the need for and type of intervention after 5 years. METHODS: We report a series of patients who were monitored with DUS imaging for a minimum of 5 years after EVAR. DUS imaging was performed in an accredited noninvasive vascular laboratory, and computed tomography angiography was only performed for abnormal DUS findings...

OBJECTIVE: Endovenous heat-induced thrombosis (EHIT) is a well-documented phenomenon that follows endovenous ablation, but the treatment, surveillance, and risk factors for EHIT have yet to be comprehensively elucidated. We sought to identify characteristics that may put patients at higher risk for development of EHIT after radiofrequency ablation (RFA) for the treatment of symptomatic superficial venous insufficiency. METHODS: A retrospective review was performed of all consecutive patients undergoing treatment with RFA to the great saphenous vein by a single surgeon from July 2013 through October 2015...

Atherosclerotic carotid stenosis (ACS) is a major cause of ischemic stroke. Screening for asymptomatic ACS is important to identify the patients who require longitudinal surveillance, medication, or endovascular surgery. The aim of this study was to assess the prevalence and risk factors for ACS and carotid plaque (CP) in Korea using a population-based screening study.We recruited participants during visits to several community welfare centers in Korea. The baseline characteristics of the study population were collected...

Although there is limited evidence that antepartum testing decreases the risk for fetal death in low-risk pregnancies, women with high-risk factors for stillbirth should undergo antenatal fetal surveillance. The strongest evidence supporting antepartum testing pertains to pregnancies complicated by intrauterine fetal growth restriction secondary to uteroplacental insufficiency. The main ultrasound-based modalities to determine fetal health are the biophysical profile, modified biophysical profile, and duplex Doppler velocimetry...

BACKGROUND: Three-dimensional contrast-enhanced ultrasound (3D-CEUS) is a novel technology allowing surgeons to view duplex ultrasound images in three dimensions with ultrasound contrast highlighting blood flow in endoleaks after endovascular aneurysm repair (EVAR). It potentially reduces the need for computed tomography angiography (CTA) and catheter angiography. This study compares 3D-CEUS with both CTA and the final vascular multidisciplinary team (MDT) diagnosis using all available imaging...

REVIEW
Olivia M McBRIDE, Roderick T Chalmers
Despite advances in endovascular strategies, surgical infrainguinal lower limb revascularization remains the gold standard treatment for critical lower limb ischemia and disabling claudication. Maintaining patency of infrainguinal vein bypass grafts has been a challenging task for vascular surgeons as they are prone to developing stenoses which may precipitate failure of the bypass. Duplex ultrasound scanning has evolved as the investigation of choice to identify vein graft lesions but graft surveillance programs using this technique remain controversial...

OBJECTIVE: Historically, edge stenosis and late thrombosis limited the effectiveness of adjunctive endovascular brachytherapy (EVBT) for in-stent restenosis (ISR) after percutaneous transluminal angioplasty (PTA) and stenting. We evaluated an updated protocol of PTA and EVBT for ISR among patients with lower extremity occlusive disease. METHODS: This is a retrospective, single-center review of patients treated with PTA and EVBT for ISR in the iliac and femoropopliteal segments between 2004 and 2012...

BACKGROUND: Tick-borne diseases caused by Anaplasma species put serious constraints on the health and production of domestic cattle in tropical and sub-tropical regions. After recovering from a primary infection, cattle typically become persistent carriers of pathogens and play a critical role in the epidemiology of the disease, acting as reservoirs of the Anaplasma spp. METHODS: In this study a duplex PCR assay was used for the simultaneous detection of Anaplasma marginale and Anaplasma phagocytophilum in cattle using two primer pairs targeting msp4 and msp2 genes, respectively...

OBJECTIVE/BACKGROUND: Surveillance after endovascular aortic aneurysm repair (EVAR) is mandatory and computed tomography angiography (CTA) is considered the standard imaging modality, although patients are exposed to ionizing radiation and nephrotoxic contrast medium. The primary aim of this study was to determine the diagnostic efficacy of duplex ultrasound (DUS) and contrast enhanced ultrasound (CEUS) using CTA as the gold standard. The secondary aim was to determine the clinical consequences of endoleaks missed by DUS and CEUS, or CTA...

African horse sickness (AHS) and equine infectious anemia (EIA) are both notifiable equid specific diseases that may present similar clinical signs. Considering the increased global movement of horses and equine products over the past decades, together with the socio-economic impact of previous AHS and EIA outbreaks, there is a clear demand for an early discrimination and a strict control of their transmission between enzootic and AHS/EIA-free regions. Currently, the individual control and prevention of AHS or EIA relies on a series of measures, including the restriction of animal movements, vector control, and the use of several laboratory techniques for viral identification, amongst others...

OBJECTIVE: The influence of endovascular aneurysm repair (EVAR) on renal function is of high concern. The question whether stent graft fixation type plays a significant role in renal outcome after EVAR is still debated. However, other factors, such as repeated contrast medium exposure, should also be considered. METHODS: We performed a two-center, stratified-cohort case control study to evaluate the influence of last-generation abdominal endografts with suprarenal (SR) vs infrarenal (IR) fixation on renal function...
