INTRODUCTION: Arteriovenous fistulas (AVF) frequently fail to mature. Postoperative ultrasounds provide objective measurements to predict unassisted AVF use for hemodialysis (unassisted use) and guide interventions to salvage nonmaturing AVFs. The optimal ultrasound criteria to assess AVF maturation are uncertain. We analyzed data from a multicenter, randomized, controlled, clinical trial to compare 2 published ultrasound maturation criteria used to predict unassisted AVF use for hemodialysis...

METHODS: In this study, 14 NFC brands representing each of the four market-categories of NFCs were selected for evaluation of fluid movement occurring during connection and disconnection of a syringe. Study objectives were to 1)theoretically estimate amount of blood reflux volume in microliters (μL) permitted by each NFC based on exact component measurements, and 2) experimentally measure NFC volume of fluid movement for disconnection reflux of negative, neutral and anti-reflux NFC and fluid movement for connection reflux of positive displacement NFC...

INTRODUCTION: Access surgery is delivered by vascular/transplant surgeons with a division that is defined by historic practice. This has resulted in an inconsistent training pattern. We aimed to design a focused, modular training program (The Brighton Vascular Access Fellowship) providing trainees with a reproducible level of exposure and competence. METHODS: The programme was 16 days over 8 weeks on a one-to-one basis with candidates expected to be performing procedures as first surgeon with ongoing, formative assessment...

Internationally, vascular access (VA) surgery is delivered in a varied and diverse fashion and subsequently, training in vascular access is poorly defined. Experience of VA during surgical training has implications on future practice. The scope of VA procedures is increasing, yet the focus in vascular training remains largely in the technical aspects of surgery rather than the more comprehensive aspects of surgery applied to dialysis and renal care. To achieve special skills in vascular access surgery may require a change to traditional training with an additional focus on developing an extended portfolio of knowledge and skills...

PURPOSE: To study the effect of x-ray radiotherapy on vascular smooth muscle cells (VSMCs) and elucidate the mechanisms in preventing neointimal hyperplasia of prosthetic vascular grafts. MATERIALS AND METHODS: In model I, twelve mongrel dogs underwent revascularization with prosthetic grafts and half the dogs underwent irradiation of the grafts at 28 Gy. In model II, human VSMCs (hVSMCs) were maintained and divided into six groups to which external radiation was applied at six different doses: 0 Gy, 2 Gy, 8 Gy, 16 Gy, 24 Gy and 30 Gy...

Cardiovascular complications are responsible not only for the high mortality, but also the morbidity of end-stage renal disease patients. Cyclic changes of fluid load, together with the altered metabolism, are responsible and are mirrored in many particular parts of the heart. A review of the mechanisms involved is presented and the role of dialysis access is highlighted.

INTRODUCTION: The study evaluated the Heparin Bioactive Surface (HBS) Viabahn Stent (W.L. Gore & Associates, -Flagstaff, Arizona) efficacy in the maintenance or re-establishment of hemodialysis. MATERIALS AND METHODS: Fifty HBS Viabahn stents deployed in 37 consecutive patients with hemodialysis dysfunction from January 2008 to May 2016 were evaluated in a single-institution retrospective review.Outcomes were stent patency intended as primary circuit patency (PP), assisted primary patency (APP), target lesion primary patency (TLPP) and secondary patency (SP)...

INTRODUCTION: The proximal cephalic vein that enters the axillary vein (cephalic arch) is a common site of stenosis in patients with upper extremity arteriovenous fistulas for hemodialysis (HD). In this study, we present the outcomes of a series of cephalic vein transposition, to determine its utility in the setting of refractory arch stenosis. METHODS: We conducted a retrospective review of patients undergoing cephalic vein transposition to manage refractory cephalic arch stenosis from January 1, 2008 to August 31, 2015...

INTRODUCTION: Despite the growing number of haemodialysis (HD) patients in India, little is known about vascular access practice. We investigated the use and cost of different vascular accesses by Indian nephrologists. METHODS: An online survey was emailed to 920 Indian nephrologists and 388 (42.1%) responded; 98.5% of whom were responsible for managing dialysis patients, 98% in hospitals. RESULTS: Sixty-four percent of patients initiated renal replacement therapy with HD, 7% with peritoneal dialysis, 10% kidney transplantation and 19% conservative care...

INTRODUCTION: Arteriovenous fistulae (AVF)-associated reactive angioendotheliomatosis (RAE) is a very rare entity (three previously reported cases in the literature) that can manifest as extremity wounds. RAE's etiopathology is unknown. CASE DESCRIPTION: We report a case of severe limb-threatening upper extremity wound with pathology-proven RAE. This lesion was previously refractory to standard wound care. There was no evidence of limb ischemia or steal syndrome, previously deemed to be the underlying cause of AVF-associated RAE in other reports...

BACKGROUND: Failure of maturation occurs in 30%-60% of arteriovenous fistula (AVF) creation for hemodialysis, with highest rates in distal radiocephalic fistulas. This is partly due to initial small blood vessel size with limited blood flow capacity. Forearm exercise has shown potential as stimulus for increasing blood vessel size in patients with end-stage renal disease (ESRD) and may promote maturation of AVFs in the upper limb when applied postoperatively. However, it is unknown if forearm exercise increases blood vessel size pre-operatively, which may contribute to more distal AVF creation and raise success rates of AVF surgery...

INTRODUCTION: Arteriovenous fistula is a lifeline for end-stage kidney disease patients on dialysis. The quality of the vein and artery to be used plays a crucial role in attaining a functioning, reliable and long-lasting arteriovenous fistula. The aim of the study is to present an alternative for haemodialysis access to preserve the upper arm vasculature for future use - the forearm loop arteriovenous fistula. METHODS: From October 2015 to September 2016, 202 patients with chronic kidney disease (CKD), stages 4 and 5, underwent arteriovenous fistula creation at the Universiti Sains Malaysia Hospital, Malaysia...

INTRODUCTION: Creating functional arteriovenous fistulae (AVF) at the wrist is challenging in paediatric patients because of the small calibre of the blood vessels. METHODS: We report our experience with AVF surgery in children younger than 15 years of age using microsurgical techniques. Twenty-five patients underwent AVF surgery between 2003 and 2015 (20 for haemodialysis, 4 for plasmapheresis and 1 for parenteral nutrition). Median (range) age was 9 (2-15) years and median weight was 24 (8-61) kg...

OBJECTIVE: To present our experience of balloon-assisted maturation with drug-eluting balloon dilation in patients with recurrent failing arteriovenous fistulae. CASE SERIES: Three patients (all males, mean age 71 years) with a complex history of failed attempts at native fistula creation underwent surgical creation of arteriovenous fistulae. Two patients had a two-stage brachio-brachial fistula and 1 had a brachio-cephalic fistula that also required subsequent elevation...

INTRODUCTION: The use of cyanoacrylate glue as sealant on the exit site of peripherally inserted central catheters (PICCs) may offer some important clinical advantages. However, concerns exist about the potential interaction between cyanoacrylate and the material of the catheter itself. The aim of this study was to investigate the possibility of damage to the catheter secondary to a long-term contact with a two-component skin glue (N-butyl + octyl cyanoacrylate). METHODS: Twelve PICCs of different brands and types were selected (11 made of polyurethane and one made of silicon)...

INTRODUCTION: Arteriovenous graft (AVG) infection can result in life-threatening sepsis and loss of vascular access. A retrospective study was performed to establish an appropriate treatment strategy for AVG infection. METHODS: A total of 50 cases of AVG infection were treated between January 2005 and June 2016. The surgical methods used were total graft excision (TGE) (n = 34), or partial graft excision (PGE) with interposition graft (n = 16). RESULTS: Infection was noted at a puncture site (n = 22), a prior incision for surgery or endovascular therapy (n = 20), and abandoned (currently unused) grafts (n = 5)...
