A master class was held at the Vascular Access at Charing Cross (VA@CX2017) conference in April 2017 with invited experts and active audience participation to discuss arteriovenous (AV) vascular access aneurysms, a serious and common complication of vascular access (VA). The natural history of aneurysms in VA is poorly defined, and although classifications exist they are not uniformly applied in studies or clinical practice. True and pseudo aneurysms of AV access occur. Whilst an AV fistula by definition is an abnormal dilatation of a blood vessel, an agreed definition of 18 mm, or 3 times accepted maturation diameter, is proposed...

INTRODUCTION: The aim of our study was to present our experience with the use of peripherally inserted central catheters (PICCs) in pediatric patients receiving autologous or allogenic blood stem-cell transplantation. The insertion of the device in older children does not require general anesthesia and does not require a surgical procedure. METHODS: From January 2014 to January 2017, 13 PICCs were inserted as a central venous device in 11 pediatric patients submitted to 14 autologous or allogeneic stem-cell transplantation, at the Bone Marrow Transplant Unit of the Children's Hospital of Brescia...

INTRODUCTION: Marked arterial adaptation is critical in permitting and sustaining the increased blood flow within an arteriovenous fistula (AVF). The aim of this investigation was to evaluate markers of arterial disease and their association with the early post-operative AVF outcomes. METHODS: We included all patients in whom an AVF had been performed after enrolment to the Renal Impairment In Secondary Care (RIISC) study. Primary AVF failure (PFL) was defined as thrombosis at six-week review...

INTRODUCTION: Lipoprotein apheresis (LA) has proven to be an effective, safe and life-saving therapy. Vascular access is needed to facilitate this treatment but has recognised complications. Despite consistency in treatment indication and duration there are no guidelines in place. The aim of this study is to characterise vascular access practice at the UK's largest LA centre and forward suggestions for future approaches. METHODS: A retrospective analysis of vascular access strategies was undertaken in all patients who received LA treatment in the low-density lipoprotein (LDL) Apheresis Unit at Harefield Hospital (Middlesex, UK) from November 2000 to March 2016...

INTRODUCTION: Although a few dialysis facilities conduct a complete blood cell count for some patients at post-dialysis, including hemoglobin, clinical findings supporting the interpretation of results are scarce. The aim of this study was to investigate the association between post-dialysis hemoglobin level and vascular access failure with clinical data. METHODS: Study design: Case crossover design. Setting: Japanese dialysis facilities, which routinely take post-dialysis blood samples, including complete blood cell counts at least once a month...

Native arteriovenous fistula (AVF) is the favorite access for hemodialysis (HD). The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) recommends its creation in most patients with renal failure. Unfortunately, intensive efforts to promote native AVF in patients with marginal vessels have increased the rate of primary fistula failure. A non-functioning fistula prompts the use of central venous catheter (CVC) that, unlike AVF, has been associated with an increased risk of morbidity and mortality among patients receiving HD...

INTRODUCTION: Accurate identification of position of a central venous catheter tip is important to reduce catheter-related complications. Nevertheless, inter-observer bias limits the accuracy of traditional method for determining tip position on chest x-ray (CXR) images. The aim of this study was to explore a simple and objective method for assessing position of peripherally inserted central catheter (PICC) tip on CXR image. METHODS: Tracheal carina was used as the landmark to identify positions of catheter tips...

INTRODUCTION: Hemodialysis catheter malfunction is problematic. We aimed to determine clinical, catheter, and hemodialysis variables that predict: (i) catheter malfunction requiring recombinant tissue-plasminogen activator (TPA) treatment and (ii) the success of TPA administration. METHODS: Clinical, catheter, and hemodialysis variables were collected from a cohort of 559 catheters (141,526 catheter days) in 175 hemodialysis patients (2008-2011). Time to, and predictors of, catheter malfunction were determined for all catheters and primary catheters only, analyzed by Cox-proportional hazard model, multi-variable logistic regression model, and mixed-effect logistic regression models...

INTRODUCTION: Central venous occlusive (CVO) disease involving the superior vena cava (SVC) and inferior vena cava (IVC) can occur frequently in patients with end-stage renal disease (ESRD) on chronic dialysis. Dialysis access is essential for the survival of these patients. CASE DESCRIPTION: We report a case of a chest wall graft creation using bovine carotid artery conduit in a patient who was experiencing life-threatening loss of dialysis access secondary to her SVC and IVC occlusion along with a hypercoagulable state...

INTRODUCTION: Advances in dialysis vascular access (DVA) management have changed where beneficiaries receive this care. The effectiveness, safety, quality, and economy of different care settings have been questioned. This study compares patient outcomes of receiving DVA services in the freestanding office-based center (FOC) to those of the hospital outpatient department (HOPD). It also examines whether outcomes differ for a centrally managed system of FOCs (CMFOC) compared to all other FOCs (AOFOC)...

PURPOSE: To report clinical performance and longitudinal assessment of hemodialysis adequacy with the Arrow-Clark VectorFlow catheter, a symmetrical-tip device with a distal lumen configuration designed to reduce platelet shear stress and catheter thrombosis. METHODS AND MATERIALS: We prospectively enrolled patients who required de novo placement of a chronic tunneled catheter for hemodialysis or exchange of a dysfunctional catheter as part of an Institutional Review Board (IRB)-approved protocol...

INTRODUCTION: In a previous paper, the authors investigated the mechanical behavior of several commercial polyurethane peripherally inserted central venous catheters (PICCs) in their 'brand new' condition. The present study represents a second step of the research activity and aims to investigate possible modifications of the PICC mechanical response, induced by long-term conservation in in vivo-like conditions, particularly when used to introduce oncologic drugs. METHODS: Eight 5 Fr single-lumen catheters from as many different vendors, were examined...
