BACKGROUND: Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedure before they rupture and require emergency surgery. Repair has traditionally been an open surgical technique that required a large incision across the abdomen. Endovascular abdominal aortic aneurysm repairs (EVARs) are now a common alternative. In this procedure, the common femoral artery is exposed via a cut-down approach and a graft introduced to the aneurysm in this way...

PURPOSE: Hemodialysis (HD) patients who are female or black receive fewer arteriovenous fistulas (AVF) and more grafts (AVG). We evaluated race- and sex-based differences for three process exposures: access surgery, peripherally-inserted central catheters (PICCs), and vascular imaging. METHODS: US Renal Data System with linked Medicare claims for patients initiating HD between April 2010 - December 2011 were used to identify PICC placement, imaging, AVF and AVG surgeries, and the vascular accesses in use at individual HD treatments...

Acute renal failure is associated with increased mortality in the Pediatric Intensive Care Unit. When anuric or oliguric renal failure occurs, the associated fluid overload may compromise respiratory function and has been shown to be associated with worse outcomes. Renal replacement therapy using continuous venous-venous hemofiltration (CVVH) allows for fluid, solute, and nitrogenous waste removal. However, large bore vascular access with placement of a double-lumen dialysis catheter is necessary to ensure effective flow rates to allow for CVVH...

The retina is an easily accessible out-pouching of the central nervous system (CNS) and thus lends itself favourable to being a biomarker of the brain. More specifically, the presence of neuronal, vascular and blood-neural barrier parallels in the eye and brain coupled with fast and inexpensive methods to quantify retinal changes make ocular biomarkers an attractive option. This includes its utility as a biomarker for multiple cerebrovascular diseases as well as a drug pharmacology and safety biomarker for the CNS...

PURPOSE: Central venous catheters (CVC) are associated with increased infection rates, morbidity and mortality compared to other hemodialysis vascular access. Chlorhexidine-impregnated transparent (CHG-transparent) dressings allow for continuous antimicrobial exposure and easy visibility of the CVC insertion site. We conducted a quality improvement project to compare catheter-related infection (CRI) rates in two dressing regimens - CHG-transparent dressings and adhesive dry gauze dressing in hemodialysis patients with tunneled CVCs...

BACKGROUND: Central vein thrombosis or obstruction is a common complication associated with central venous catheters placed for intermittent hemodialysis. The reported outcomes of percutaneous catheter-based interventions reveal high rates of lesion recurrence with varying and frequently limited patency intervals. We present the case of open venous bypass in the treatment of catheter-associated chronic central vein occlusion. METHODS: We report a case of symptomatic arm swelling secondary to central vein stenosis and failed endovascular venous intervention treated by central vein bypass with prosthetic graft through median sternotomy...

Retained intravascular foreign body is a well-known complication of central venous access placement in children as well as adults. Most of these foreign bodies are radio-opaque and hence are removed under fluoroscopy guidance. In our case, we describe the removal of an intracardiac radiolucent foreign body in an infant utilizing a combination technique - transesophageal echocardiogram and fluoroscopy.

OBJECTIVES: Central venous access in critically ill, small infants remains technically challenging even in experienced hands. Several vascular accesses exist, but the subclavian vein is often preferred for central venous catheter insertion in infants where abdominal malformation and/or closure of the vein preclude the use of umbilical venous catheters, as catheterization of the subclavian vein is easier in very short necks than the internal jugular vein for age-related anatomical reasons...

BACKGROUND: Economic, cultural, and geographical reasons usually limit the access to specialized health centers in developing countries, especially in rural areas. Peruvian health system indicators still highlight significant unmet clinical need for neurosurgical patients. Our project is to develop the first highly specialized neurosurgical center in the EsSalud hospital of Trujillo, with the goal to improve the treatment of neurosurgical diseases in that region, thus optimizing their outcomes while decreasing expensive and risky patients transfer to the neurosurgical departments in the capital district...

Extracorporeal carbon dioxide removal (ECCO2R) is increasingly considered a viable therapeutic approach in the management of hypercapnic lung failure in order to avoid intubation or to allow lung-protective ventilator settings. This study aimed to analyze efficacy and safety of a minimal-invasive ECCO2R device, the Homburg lung. The Homburg lung is a pump-driven system for veno-venous ECCO2R with ¼" tubing and a 0.8 m surface oxygenator. Vascular access is usually established via a 19F/21cm bilumen cannula in the right internal jugular vein...

BACKGROUND: Cardiovascular diseases (CVDs) are the leading cause of global mortality. Among the CVDs, acute vascular events (AVE) mainly ischemic heart diseases and stroke are the largest contributors. To achieve 25% reduction in preventable deaths from CVDs by 2025, health systems need to be equipped with extended service coverage in order to provide person-centered care. The overall goal of this proposed study is to assess access to health care in-terms of service availability, care seeking patterns and barriers to access care after AVE in rural Bangladesh...

BACKGROUND: The continuous monitoring of vital parameters and subsequent therapy belong to the core duties of anaesthetists during acute trauma resuscitation in the trauma room. Important procedures may include placement of arterial lines and central venous catheters (CVCs). Knowledge of indication, performance and localization of invasive catheterisation of trauma care in Germany is scarce. METHODS: After approval of the German Society of Anaesthesiology and Intensive Care Medicine we conducted an online survey about arterial and central venous catheterisation of severely injured patients with consideration of common practice used by anaesthetists in German trauma rooms...

: Peripherally inserted central catheter (PICC) and umbilical venous catheter (UVC) in terms of success rate, complications, cost and time of insertion in neonatal intensive care were compared. Neonates requiring vascular access for minimum 7 days were included. Sample size of 72 per group was determined. Trial was registered at Clinical Trials Registry of India (CTRI/2015/02/005529). Success rates of the UVC and PICC were 68.1% and 65.3%, respectively (p = 0.724). Mean (SD) time needed for PICC and UVC insertion was 34...

Importance: Vascular access dysfunction is a leading cause of morbidity and mortality in patients requiring hemodialysis. Arteriovenous fistulae are preferred over synthetic grafts and central venous catheters due to superior long-term outcomes and lower health care costs, but increasing their use is limited by early thrombosis and maturation failure. ω-3 Polyunsaturated fatty acids (fish oils) have pleiotropic effects on vascular biology and inflammation and aspirin impairs platelet aggregation, which may reduce access failure...

PURPOSE: The lower extremity has received its fair share of attention as a vascular access site in patients who have exhausted their upper arm vessels. However, experiences with lower extremity arteriovenous grafts (AVGs) have so far been disappointing because of high infection rates and severe limb ischemia. We report our experience with hemodialysis access from the lower extremity. MATERIALS AND METHODS: A retrospective review of 60 lower extremity AVGs created between January 2003 and December 2011 was performed...

Endovascular repair has become the treatment of choice for thoracic and abdominal aortic pathologies in the last decades, and is associated with excellent results in terms of perioperative, mid- and long-term morbidity and mortality. Access vessels play a central role in these procedures since access-related issues can increase the rates of technical failures and determine clinical complications for the patient. Therefore, accurate preoperative clinical evaluation and review of the preoperative images are mandatory...

Given the central role of genetic factors in the pathogenesis of common neurodegenerative disorders, it is critical that mechanistic studies in human tissue are interpreted in a genetically enlightened context. To address this, we performed exome sequencing and copy number variant analysis on 1511 frozen human brains with a diagnosis of Alzheimer's disease (AD, n = 289), frontotemporal dementia/amyotrophic lateral sclerosis (FTD/ALS, n = 252), Creutzfeldt-Jakob disease (CJD, n = 239), Parkinson's disease (PD, n = 39), dementia with Lewy bodies (DLB, n = 58), other neurodegenerative, vascular, or neurogenetic disorders (n = 266), and controls with no significant neuropathology (n = 368)...
