BACKGROUND: Arteriovenous accesses (AVA) in patients performing hemodialysis (HD) are labeled "permanent" for AV fistulas (AVF) or grafts (AVG) and "temporary" for tunneled central venous catheters (TCVC). Durability and outcomes of permanent vascular accesses based on the sequence in which they were placed or used receives little attention. This study analyzed longitudinal transitions between TCVC-based and AVA-based HD outcomes according to the order of placement. METHODS: All 391 patients initiating chronic HD via a TCVC between 2012 and 2013 at 12 outpatient academic dialysis units were included in this study...

Objective With the implementation of the K-DOQI guidelines, more patients are in need of long-term dialysis catheters until maturation of the arteriovenous fistula. However, on occasion, when placing a tunneled cuffed catheter for hemodialysis, we have encountered difficulty with passing the guidewire in spite of demonstration of a patent cervical portion of the internal jugular vein on duplex. Herein, we review our experience with intraoperative venoplasty for placement of Tesio™ catheters (Medcomp Harleysville, PA)...

Autogenous arteriovenous fistulas (AVF) are the preferred access for hemodialysis. AVF occasionally develop venous aneurysms and we report a modified staple aneurysmorrhaphy technique for treatment. Briefly, the lateral wall of the venous aneurysm is dissected and a longitudinal staple resection performed. Adjunct procedures include inflow banding and outflow venous angioplasty with possible stenting. In this initial experience, 20 aneurysms were resected in 17 patients. The average AVF age at time of repair was 5...

BACKGROUND: Despite improved health outcomes associated with arteriovenous fistulas, 80% of Americans initiate hemodialysis using a catheter, influenced by low socioeconomic status among other factors. Risk factors for incident catheter use in safety-net populations are unknown. Our objective was to identify factors associated with incident catheter use among hemodialysis patients at one safety-net hospital, with a goal of informing fistula placement initiatives targeted at safety-net populations more generally...

INTRODUCTION: Contemporary dogma has classically attributed hand dysfunction following hemodialysis arteriovenous fistula (AVF) placement to regional ischemia. We hypothesize that hemodynamic perturbations alone do not entirely explain the postoperative changes in hand function and, furthermore, that various elements of hand function are differentially affected following surgery. METHODS: Bilateral wrist and digital pressures and upper extremity nerve conduction tests were recorded preoperatively and at 6 weeks and 6 months following upper extremity AVF construction in 46 patients...

OBJECT: Scalp arteriovenous fistulas (AVFs) are rare lesions and may occur spontaneously or secondary to head trauma. The standard treating strategy for these lesions has not been established to date. We present three cases of successful treatment of scalp AVFs using a combination of Onyx-18 and coils via a transvenous approach. METHODS: The database of patients at Huashan Hospital, Fudan University, Shanghai, China was reviewed. The patients with scalp AVFs treated with Onyx-18 and coils via a transvenous approach were included...

BACKGROUND: Development of recalcitrant stenotic lesions of the cephalic arch is a significant cause of dysfunction of brachiocephalic access arteriovenous fistulas (AVFs). Endovascular and surgical therapy can be used to treat cephalic arch stenosis. The aim of this study was to evaluate the outcomes of endovascular and surgical interventions for cephalic arch stenosis. METHODS: A retrospective review of all patients during a 16-year period with a compromised but not occluded brachiocephalic AVF due to cephalic arch stenosis was undertaken...

BACKGROUND AND OBJECTIVES: The optimal type of initial permanent access for hemodialysis among the elderly is controversial. Duration of central venous catheter dependence, patient comorbidities, and life expectancy are important considerations in whether to place an arteriovenous fistula or graft. We used an observational study design to compare clinical outcomes in elderly patients who initiated hemodialysis with a central venous catheter and subsequently had an arteriovenous fistula or graft placed...

REVIEW
Hector Ferral, Marc J Alonzo
A transjugular venous access is an alternative approach for endovascular intervention in upper-extremity dialysis arteriovenous fistulae and grafts. The transjugular access is recommended for patients who have an unfavorable anatomy for the direct arm access approach. Ultrasound evaluation of the arteriovenous access is essential before intervention and includes evaluation of the inflow artery and outflow vein diameters, arteriovenous anastomosis, and the entire outflow vein, specifically looking into potential problem areas...

Placement of autogenous arteriovenous fistula (AVF) is one of the basic needs in hemodialysis patients. Although many studies have investigated the complications of AVF placement, the complaints expressed by patients have not been studied in a long-term study. The purpose of this study was to evaluate the incidence of complaints after placement of autogenous AVF in patients undergoing chronic hemodialysis. This cohort study was conducted on patients with end-stage renal disease undergoing AVF placement who were referred to Imam Reza hospital in Mashhad, Iran, from January 2015 to June 2016...

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: Valvular disease and pulmonary hypertension are common conditions in haemodialysis patients. In presence of tricuspid regurgitation, an increased retrograde blood flow into the right atrium during ventricle systole results in a typical modification of the normal venous waveform, creating a giant c-v wave. This condition clinically appears as a venous palpable pulsation within the internal jugular vein, also known as Lancisi's sign. CASE REPORT: An 83-year-old woman underwent haemodialysis for 9 years...

Patients in the United States frequently initiate hemodialysis with a central venous catheter (CVC) and subsequently undergo placement of a new arteriovenous fistula (AVF) or arteriovenous graft (AVG). Little is known about the clinical and economic effects of initial vascular access choice. We identified 479 patients starting hemodialysis with a CVC at a large medical center (during 2004-2012) who subsequently had an AVF (n=295) or AVG (n=105) placed or no arteriovenous access (CVC group, n=71). Compared with patients receiving an AVG, those receiving an AVF had more frequent surgical access procedures per year (1...

INTRODUCTION: Transposed basilic vein arteriovenous fistulas suffer from stenosis at their basilic angle of transposition (BAT). This lesion exhibits frequent recurrence after angioplasty. The primary goal of this study was to determine the effect of stent-graft placement on BAT lesion- and access-patency. The secondary goals were to determine the frequency of intervention pre- and post-stent placement and stent-associated stenosis. METHODS: Thirty-seven cases had stent-grafts placed at their BAT to manage stenosis...

The vascular access is the lifeline for the hemodialysis patient. In the United States, the Fistula First Breakthrough Initiative (FFBI) has been influential in improving use of arteriovenous fistulas (AVF) in prevalent hemodialysis patients. Currently, prevalent AVF rates are near the goal of 66% set forth by the original FFBI. However, central venous catheter (CVC) rates remain very high in the United States in patients initiating hemodialysis, nearly exceeding 80%. A new direction of the of the FFBI has focused on strategies to reduce CVC use, and subsequently the FFBI has now been renamed the "Fistula First-Catheter Last Initiative"...

BACKGROUND: Ultrasound-guided percutaneous endovascular treatment of arteriovenous fistula (AVF) or graft failure is an alternative to radiologically-guided angioplastic methods. Its main advantages are that it can be used with open or percutaneous access, using no contrast media and no radiation. The aim of this study was to analyze the results of ultrasound-guided endovascular treatment of arteriovenous access failure. MATERIAL AND METHODS: Preoperative ultrasound was used to determine the degree of stenosis and the size of balloon used in angioplasty...
