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...

INTRODUCTION: Central venous catheter (CVC) access is commonplace in intensive care units. Patients undergoing computed tomographic angiography require injection of contrast at high flow rates (4.5 mL/s), often CVC access is not used due to safety concerns. The CVC might rupture at high flow rates, resulting in CVC fragmentation and embolization or contrast extravasation.The objective of this study is to determine the pressure required to burst a CVC under static load and compare this to the pressure generated by injection of contrast at high flow rates (dynamic load) through the distal (16-g) lumen of a triple-lumen CVC...

INTRODUCTION: The aim of this study is to compare an intravenous (IV) catheter system which uses a retractable guidewire (RG-IV) designed to facilitate IV placement with a conventional IV (C-IV) catheter control. MATERIALS AND METHODS: A prospective, randomized design was used. Patients referred to interventional radiology for outpatient procedures were offered participation. Enrollment occurred between August and November 2013. Patients were assigned to receive the RG-IV or C-IV in a 1:1 randomization scheme...

BACKGROUND: Malpositioned central venous access device (CVAD) tip locations can cause significant mechanical and chemical vessel-related injuries and complications if left in inappropriate positions.The aim of this study is to determine the use of a high-flow flush technique (HFFT) in successful correction of malpositioned catheters into the lower superior vena cava or cavoatrial junction and provide a cost comparison to interventional/fluoroscopic-based repositioning. METHODS: This is a Retrospective chart and radiographic review of all inserted CVADs found malpositioned between 1996-2014 in a multi-specialty 1000-bed tertiary trauma center in Sydney, Australia...

INTRODUCTION: We present an unreported cause of banding failure for flow restriction in dramatically enlarged arteriovenous fistulas (AVFs). CASE SERIES: Four patients operated in different institutions by two different surgeons experienced band failure within 6 months of the initially successful operation for AVF flow restriction. Prior to the initial banding procedure, each patient's AVF was noted to have major dilatation of the post-anastomotic segment (>2 cm)...

INTRODUCTION: The potential drawbacks of tunneled-cuffed catheters are complications such as local or systemic infection, dislodgment, rupture, malfunction, and deep venous thrombosis. Aim of this study is to describe the incidence of complications, focusing on dislodgment and on the role of new securement devices in reducing this annoying issue. METHODS: We enrolled all pediatric patients with tunneled-cuffed central venous catheters (CVCs) inserted at the Giannina Gaslini Institute during a 16-month period...

INTRODUCTION: Early access failure is an important complication of autogenous arteriovenous fistulas (AVFs). We prospectively monitored patients who underwent AVF creation using ultrasonography. METHODS: Color flow imaging was used to assess access blood flow in patients undergoing creation of a new AVF in the distal forearm preoperatively and at 1 day and 1 week postoperatively. We measured the flow volume (FV) and resistive index (RI) of the brachial artery, and the internal diameter of the brachial artery and outflow vein...

INTRODUCTION: Distal autogenous arteriovenous fistula (dAVF), considered the "gold standard" vascular access for haemodialysis, suffers from a high rate of impaired maturation. One of the usual causes is low-flow associated forearm arterial stenosis. In such cases, endovascular treatment by percutaneous transluminal angioplasty represents a helpful option to enable maturation of the vascular access.Currently, there are few reports concerning the treatment of this complication. Therefore, we describe our single-centre experience based on a retrospective review of prospectively collected data...

INTRODUCTION: Neutral-valve closed-system connectors can reduce the frequency of catheter colonization. Commercially available closed system connectors need to be tested and compared with each other to assess how they protect against contamination. We aimed to compare, in vitro, the efficacy of connectors NeutraClear® and MicroClave® against contamination under conditions of daily clinical practice. METHODS: The model consisted of a set of 200 blood culture bottles (BCBs) with a cannula inserted (100 closed with NeutraClear® and 100 closed with MicroClave®) that were assessed in two experiments while instilling 1 mL of saline: manipulation based on the standard of care and manipulation using gloves impregnated with a 0...

INTRODUCTION: The peripherally inserted central catheters (PICCs) are vascular access devices (VAD) that are increasingly being used in the pediatric population. If a small vein caliber prevents positioning the catheter in the arm, the following step is to position the same catheter in the supraclavicular area, which can be defined as an off-label use or "atypical" approach, first described by Pittiruti. MATERIALS AND METHODS: We retrospectively reviewed PICC positioning with puncture-site in the supra-clavicular area ("atypical" PICC insertion) and then tunneled on the chest...

INTRODUCTION: Functional arteriovenous fistula (AVF) is the best vascular access for end-stage renal disease patients. AVF maturation is variable and many require additional interventions to achieve functionality. Long-term benefits of such interventions are unclear. Using a protocol for AVF planning, creation, maturation evaluation and performing interventions based on objective findings along with maintaining a database on follow-up is necessary to evaluate this question.The aim of this study is to evaluate the long-term outcome of newly constructed AVFs using a protocol-based approach in a tertiary care academic center...

INTRODUCTION: Children requiring long-term hemodialysis often face significant challenges due to their young age and small-vessel caliber for arteriovenous (AV) access creation. In this study, we report our experience of staged basilic vein transposition (BVT) in pediatric patients. METHODS: All patients undergoing staged BVT at a tertiary care pediatric hospital from 2003 to 2015 were reviewed. Indications for staged BVT included inadequate cephalic conduit or failed AV fistula using cephalic vein...
