INTRODUCTION: Hostile anatomic characteristics in patients undergoing endovascular abdominal aortic aneurysm repair (EVAR) may lead to technical nonsuccess of the procedure, late complications, reintervention or death. The authors analyzed anatomical abdominal aortic aneurysm specific considerations so as technical endoprosthesis implantation and correlate them with endoleak development and postoperative survival. METHODS: Authors retrospectively reviewed all consecutive, elective, EVAR's that occurred between 2010 and 2016, with available data, at one institution for abdominal, infra renal, aortic aneurysms...

BACKGROUND: Venous thromboembolism is a cause of morbidity and mortality in trauma patients. Chemoprophylaxis with low-molecular-weight heparin at a standardized dose is recommended. Conventional chemoprophylaxis may be inadequate. We hypothesized that a weight-adjusted enoxaparin prophylaxis regimen would reduce the frequency of venous thromboembolism in hospitalized trauma patients and at 90-day follow-up. METHODS: This prospective, randomized pilot study enrolled adult patients admitted to a level 1 trauma center between July 2013 and January 2015...

BACKGROUND: Given the risk of artemisinin resistance spreading from the Greater Mekong sub-region, prospective monitoring in sub-Saharan Africa should be expedited. Molecular biology techniques used for monitoring rely on the detection of k13 validated mutants by using PCR and Sanger sequencing approach, usually not available in malaria endemic areas. METHODS: A semi-automated workflow based on the easyMAG® platform and the Argene Solution® (bioMérieux, Marcy l'Etoile, France) as a field-based surveillance tool operable at national level was developed in four steps...

BACKGROUND: Hand ischemia following trauma in children is rare and the natural history after upper extremity arterial bypass in children is unknown. We hypothesize children with brachial artery repair are at long term risk of developing aneurysmal degeneration or Thrombosis thus necessitating annual duplex ultrasonography and physical examination. STUDY DESIGN: A retrospective review of children who had brachial artery repair (bypass or vein patch) for hand ischemia secondary to trauma at a level I trauma pediatric hospital was performed...

INTRODUCTION: Diagnosis of endoleaks is imperative to prevent failure of endovascular aneurysm repairs (EVARs). The gold standard for diagnosis of endoleaks is catheter-directed subtraction angiography, which is not a practicable choice for surveillance. CT angiography (CTA) is the historical surveillance modality of choice. Concerns over cost, potential nephrotoxicity of contrast agents and repeated radiation exposure led to colour duplex ultrasound scan (CDUS) becoming an established alternative...

INTRODUCTION: Historically, ureteroceles were surgically treated, as patients were diagnosed after developing symptoms. However, with the advance of fetal medicine, antenatal detection has provided an opportunity to look at the natural history of ureteroceles. OBJECTIVES: With data derived from a retrospective chart review of patients with ureteroceles that were detected antenatally, the current study aimed to determine which group of children would be at risk for failure on active surveillance...

BACKGROUND: The D-dimer (DD) level combined with the pretest Wells criteria probability (WCP) score can safely exclude deep venous thrombosis (DVT). The objective of this study was to examine the correlation between DD results alongside WCP score with findings on venous duplex ultrasound (VDU). The hypothesis is that VDU remains overutilized in low-risk patients with negative DD and that higher DD levels may correlate with thrombus burden and location. METHODS: Patients who presented to a high-volume tertiary care center with lower limb swelling with or without associated pain were retrospectively examined through June and July for 4 consecutive years (2012 to 2015)...

BACKGROUND: Duplex ultrasonography (DUS) currently has limited applicability in the diagnosis and surveillance of thoracic aortic pathologies because of associated limitations. This study investigates the feasibility of using an optimised DUS protocol to detect descending thoracic aortic pathology. METHODS: Forty patients were scanned (20 cases and 20 controls). All patients but one had a technically adequate assessment of the thoracic aorta (at least one view of the descending thoracic aorta)...

OBJECTIVE: Type II endoleaks (T2ELs) are commonly observed after endovascular aneurysm repair (EVAR). We sought to determine whether time at onset of T2ELs correlated with the need to intervene based on sac expansion or rupture. METHODS: Between 1998 and 2015, 462 EVARs performed at our institution had duplex ultrasound surveillance in our accredited noninvasive vascular laboratory. Computed tomography and arteriography were reserved for abnormal duplex ultrasound findings...

OBJECTIVE: The objective of this study was to determine the natural progression of popliteal artery aneurysms (PAAs) and clinical variables associated with their accelerated growth. METHODS: Retrospective chart review of 224 patients with encounters between January 2008 and May 2016 and with at least one PAA was conducted. From this group, 65 asymptomatic patients had either unilateral (n = 43) or bilateral (n = 22) PAAs that were observed for at least 1 year of medical management before intervention...

OBJECTIVE: Because of advances in technology and experience of the operator, endovascular aneurysm repair (EVAR) has supplanted open repair to treat abdominal aortic aneurysm (AAA). The low 30-day mortality and morbidity of EVAR make the endovascular approach particularly suitable for patients at high surgical risk. However, endoleak or endograft migration requiring secondary intervention or open surgical conversion is a limitation of EVAR. The Nellix system (Endologix, Inc, Irvine, Calif) has been designed to seal the entire AAA to overcome these limitations with EVAR...

OBJECTIVE: Magnetic resonance of the carotid arteries provides important insight into plaque composition and vulnerability in addition to the traditional measure of stenosis. The purpose of this study was to evaluate the cost-effectiveness of MR imaging as a first-line modality to assess carotid disease and guide management for high-risk patients with <50% stenosis. METHODS: Using TreeAge Pro, a cost-effectiveness simulation was conducted comparing two strategies: (a) standard of care first-line carotid duplex ultrasound (DUS) with regular follow-up, vs (b) first-line MR assessment of stenosis and intraplaque haemorrhage (MRIPH) in which patients with IPH received annual DUS surveillance and immediate carotid endarterectomy in case of plaque progression...

Importance: Ensuring that patients undergo surveillance imaging after surgery is a key quality metric after many vascular procedures. It is unclear whether hospital participation in a national quality improvement registry such as the Vascular Quality Initiative (VQI) achieves this goal. Objective: To determine if hospital participation in the VQI registry is associated with increased rates of surveillance imaging after vascular procedures. Design, Setting, and Participants: A quasi-experimental study used Medicare claims to study 2174 US hospitals in which 1 530 102 patients had undergone an endovascular abdominal aortic aneurysm repair (EVAR), 1 403 067 patients had undergone a lower extremity bypass (LEB) or peripheral vascular intervention (PVI), and 294 942 patients had undergone carotid endarterectomy (CEA) and carotid artery stenting (CAS) procedures between January 1, 2007, and December 31, 2012...

BACKGROUND: Duplex ultrasound is the first choice in diagnostics and surveillance of stenoses of the internal carotid arteries before and even after surgery. Therefore, the quality of duplex ultrasound is crucial to investigate these vascular pathologies. OBJECTIVE: Aim of this study was the evaluation whether different surgical techniques affect the postoperative quality of duplex ultrasound. METHODS: In a time period from January to May 2015 duplex ultrasound of the cervical vessels was performed in 75 patients after unilateral endarterectomy of the internal carotid artery at our department between 2006 and 2012...

Aedes aegypti (L.) and Ae. albopictus (Skuse) are important arbovirus vectors in the United States, and the recent emergence of Zika virus disease as a public health concern in the Americas has reinforced a need for tools to rapidly distinguish between these species in collections made by vector control agencies. We developed a duplex real-time PCR assay that detects both species and does not cross-amplify in any of the other seven Aedes species tested. The lower limit of detection for our assay is equivalent to ∼0...
