Hemodialysis (HD) is the most common mode of renal replacement therapy for end-stage renal disease (ESRD) patients in India. However, the practice and pattern of dialysis in a hospital serving rural population is largely unknown. A prospective study of 127 ESRD patients initiated on HD between January 2013 and December 2014 was done. The study included 101 males and 26 females, with a mean age of 50.05 ± 13.80 years. Native kidney disease was unknown in 45.67% of patients as they presented very late in their disease course...

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...

OBJECTIVES: To systematically assess the difference between both procedures in terms of access maturation, patency and postoperative complications. BACKGROUND: An arteriovenous fistula (AVF) is the best modality for haemodialysis (HD) access. The end-to-side (ETS) technique has been suggested in the literature to produce superior results to the side-to-side approach; however, in the absence of a systematic review, this practice remains debatable. METHODS: Online search for randomised controlled trials (RCTs) and observational studies that compared the end-to-side versus the side-to-side anastomosis techniques in creating an upper limb AVF...

BACKGROUND: Arteriovenous fistula (AVF), permanent catheter (PC), and vascular graft are three vascular access types used for hemodialysis procedure. Due to insufficient reliable information on the comparison between AVF and PC, this study was conducted to compare AVF and PC regarding dialysis adequacy. MATERIALS AND METHODS: This prospective study was carried out from March, 2013 to September, 2013. In this study, 76 hemodialysis patients were enrolled and assigned to two unequal groups of AVF and PC...

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...

ObjectivesAs high health care costs are increasing scrutinized, a movement toward reducing patient hospital admissions and lengths of stay has emerged, particularly for operations that may be performed safely in the outpatient setting. Our aim is to describe recent temporal trends in the proportion of dialysis access procedures performed on an inpatient vs. outpatient basis, and to determine the effects of these changes on perioperative morbidity and mortality. MethodsThe 2005-2008 ACS NSQIP database was queried for all primary arteriovenous fistula (AVF) procedures using CPT codes...

We report here a typical case of a patient on hemodialysis (HD) for end-stage renal disease (ESRD) in India that highlights some of the management issues encountered in a country with an enormous burden of ESRD and major challenges of underdialysis and management of comorbidities. The patient, a 42-year-old multiparous woman with chronic kidney disease (CKD) stage V, type 2 diabetes mellitus, and hypertension is a homemaker from a middle-class family, living in a large city, with no family history of CKD. From May 2013 to December 2016, she has been receiving twice-weekly maintenance HD for 4 h (intermittent HD); access was via an internal jugular line initially and then via a left brachiocephalic arteriovenous fistula (AVF) from late June 2013...

In hemodialysis patients the principal cause of arteriovenous fistula dysfunction is stenosis. Matrix-metalloproteinase-2 is implicated in the pathophysiological mechanism of stenosis development. Our study tried to assess the clinical impact of this protease on arteriovenous fistula survival. Seventy-nine prevalent dialysis patients with functional arteriovenous fistulas were included in the study. The presence of stenosis and the serum levels of matrix-metalloproteinase-2 were determined at the beginning of the study...

Hemodialysis catheters are associated with higher risks of complications compared to arteriovenous fistulas and grafts. Some common complications of dialysis catheters include infection, thrombus formation, central venous stenosis, and mechanical dysfunction. Rarely, catheters can become firmly adhered to a vessel wall. Catheter adhesion is a serious complication that can impact the delivery of safe and effective dialysis to affected patients. Adherent catheters commonly present insidiously with no overt diagnostic signs and symptoms or antecedent catheter malfunction...

INTRODUCTION: Dialysis patients aged ≥70 years derive improved life expectancy through kidney transplantation compared to their waitlisted counterparts, but guidelines are not clear about how to identify appropriate transplantation candidates. We developed a clinical prediction score to identify elderly dialysis patients with expected 5-year survival appropriate for kidney transplantation (>5 years). METHODS: Incident dialysis patients in 2006-2009 aged ≥70 were identified from the United States Renal Data System database and divided into derivation and validation cohorts...

BACKGROUND: Arteriovenous fistulae are the currently recommended gold standard vascular access modality for haemodialysis because of their prolonged patency, improved durability, and low risk of infection for those that mature. However, notable disadvantages are observed in terms of protracted maturation time, associated high rates of catheter use, and substantial abandonment rates. The aim of this study was to quantitatively summarize the outcomes of fistula patency, infection, maturation, and abandonment published in the scientific literature...

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...
