INTRODUCTION: The prophylactic use of recombinant tissue plasminogen activator once weekly reduces the incidence rate of tunneled cuffed catheter (TCC) malfunction and bacteremia as compared to the exclusive use of heparin as locking solution. Restricting the use of prophylactic thrombolytic agents to patients with a history of thrombotic TCC malfunction could be more cost effective. We conduct a multicenter, double-blind, randomized controlled trial and test the hypothesis that weekly use of urokinase lock will reduce the incidence of thrombotic malfunction by 50% in prevalent hemodialysis patients with a history of thrombotic malfunction...

INTRODUCTION: An effective approach to prevent hemodialysis vascular access dysfunction is still unclear despite previous studies, which have shown conflicting results of several drugs on vascular access outcomes. In this study, we focused on diabetic hemodialysis patients with native arteriovenous fistula and evaluated the impact of statin treatment on vascular access patency. METHODS: A retrospective cohort study of 268 consecutive patients who newly started hemodialysis due to diabetic nephropathy between January 2011 and December 2013 at Japan Community Health Care Organization Sendai Hospital was performed and the patients were followed for two years...

INTRODUCTION: The palpation technique is generally used for radial artery catheterisation, but is associated with a high rate of failure and complications. Dynamic needle tip positioning (DNTP) is a new ultrasound-guided technique. We aimed to compare the traditional palpation technique with DNTP performed by four anaesthesiology residents. METHODS: The study was a randomised, controlled, patient-blinded, crossover study. Fourty patients underwent bilateral radial artery catheterisation using both techniques...

We present a case of an iatrogenic lymphocutaneous fistula secondary to placement of a tunneled, large bore (14.5 Fr) right-sided internal jugular vein for plasmapheresis to treat antibody-mediated kidney transplant rejection. While iatrogenic lymphatic leaks caused by neck and thoracic surgeries are well described in the literature, lymphatic leak or lymphocutaneous fistula resulting from image-guided placement of a central venous catheter through the right internal jugular vein has yet to be described. We also describe the successful percutaneous treatment of this lymphocutaneous fistula using a combination of n-butyl cyanoacrylate glue and embolization coils...

INTRODUCTION: We report the use of a new ultrasound technique to evaluate the axial and lateral components of a complex flow in the arteriovenous fistula (AVF). Vector Flow Imaging (VFI) allows to identify different components of the flow in every direction, even orthogonal to the flow streamline, represented by many single vectors. VFI could help to identify flow alterations in AVF, probably responsible for its malfunction. METHODS: From February to June 2016, 14 consecutive patients with upper-limb AVF were examined with a Resona 7 (Mindray, Shenzhen, China) ultrasound scanner equipped with VFI...

INTRODUCTION: Children with special health-care needs are an emerging and consistent population. In a subset of children with medical complexity (CMC) a continuous access to the central vascular system is advisable to eliminate unnecessary pain and stress and to improve home management and palliative care. METHODS: The surgical registry of a tertiary hospital was checked in order to identify CMC who underwent totally implantable venous access device (VAD) placement...

BACKGROUND: Despite their well-recognised shortcomings, haemodialysis catheters (HDCs) remain an important form of haemodialysis access for many patients. There are several HDCs commercially available, each differing considerably in design, which is known to significantly influence performance and survival. We sought to determine which of two tunnelled HDCs, DuraMax® (Angiodynamics, NY, USA) or SplitCath® (MedComp, PA, USA) delivers the best performance, safety and reliability for dialysis patients...

OBJECTIVE: The arteriovenous fistula (AVF) is the preferred method of long-term haemodialysis. However, it has been shown to have a substantial rate of maturation failure. The formation of an AVF creates haemodynamic changes to blood flow in the arm with diversion of blood away from the distal circulation into the low pressure venous system, in turn, leading to thermal changes distally. In this study, we aimed to assess the novel use of infrared thermal imaging as a predictor of arteriovenous maturation...

BACKGROUND: Perioperative ultrasound performed by the operative surgeon can improve outcomes of vascular access surgery. We present the case of a patient referred for dysfunctional vascular access with two separate and patent right arm arteriovenous fistulas (AVF). Pre-operative ultrasound vessel mapping defined the complex anatomy and intraoperative ultrasound allowed the optimal surgical approach for access salvage while avoiding the need for catheter placement. CASE REPORT: A 45-year-old male patient of African descent presented with a malfunctioning right forearm AVF and aneurysm formation in the arm...

BACKGROUND: The coexistence of a double superior vena cava (SVC) and a partially left inferior vena cava (PLIVC) with a circumaortic collar, associated with other congenital malformations, was not described previously. CASE DESCRIPTION: We present a 33-year-old woman in hemodialysis with complete exhaustion of the brachial routes for vascular access, admitted to our Nephrology Unit for a long-term central venous catheter (CVC) implant, usually by us performed under EchoScopic Technique (EST), an echographic venipuncture followed by continuous radioscopic control of guidewire and catheter in all the steps of implant...

There is a consensus in the literature that regional anesthesia (RA) improves local hemodynamic parameters in comparison to local anesthesia (LA) during arteriovenous fistula (AVF) surgical construction. However, the effects of both techniques on fistula patency and failure rates are still controversial. The aim of this meta-analysis is to synthesize evidence from published randomized trials and observational studies regarding the safety and efficacy of RA versus LA in AVF surgical construction. A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central retrieved six randomized trials (462 patients) and one retrospective study (408 patients)...

BACKGROUND: Patients on chronic hemodialysis often have acquired coagulopathy that can aggravate bleeding from puncture site after needle extraction. Chitosan-based pads have been reported to accelerate hemostasis even in the presence of coagulopathy. The aim of this study was to evaluate the hemostatic efficacy of the chitosan pads compared to gauze pads, applied for local hemostasis. METHODS: A crossover study in a cohort of patients on hemodialysis with extended time to hemostasis after needle extraction...

INTRODUCTION: We report the use of a newly described regional technique, ultrasound-guided costoclavicular approach infraclavicular brachial plexus block for surgical anesthesia in two high-risk patients undergoing 2nd stage transposition of basilic vein fistula. METHODS: Both patients had features of difficult airway, American Society of Anesthesiologists (ASA) physical status class III and central venous occlusive disease. The common approach, i.e., ultrasound-guided supraclavicular brachial plexus block was technically difficult with inherent risk of vascular puncture due to dilated venous collaterals at the supraclavicular area possibly compromising block quality...

INTRODUCTION: The efficacy of antiplatelet agents in preventing thrombosis in newly formed arteriovenous graft (AVG) in hemodialysis (HD) patients has been extensively examined. The aim of this study was to investigate the possible effect of initiation of antiplatelet medications on preventing AVG thrombosis recurrence after surgical thrombectomy for acute occlusion in HD patients. Whether post-operatively antiplatelet medications have protective effects on the patency or longevity of AVG after surgical thrombectomy in HD patients has not been investigated...
