The influence of a doppler ultrasound in arteriovenous fistula for dialysis failure related to some risk factors

J. bras. nefrol; 42 (2), 2020
ABSTRACT Introduction: The increasing prevalence of chronic kidney disease has increased the demand for arteriovenous fistula (AVF) care. The objective of this study was to assess the relationship between some risk factors for AVF failure (advanced age, female sex, diabetes, obesity, central venous cath...

Hemodialysis Vascular access maintenance in the Covid-19 pandemic: Positioning paper from the Interventional Nephrology Committee of the Brazilian Society of Nephrology

J. bras. nefrol; 42 (2,supl.1), 2020
ABSTRACT Vascular accesses for hemodialysis are considered the patient's lifeline and their maintenance is essential for treatment continuity. Following the example of institutions in other countries affected by the Covid-19 pandemic, the Brazilian Society of Nephrology developed these guidelines for hea...

Relevance of a skilled vascular surgeon and optimized facility practices in the long-term patency of arteriovenous fistulas: a prospective study

J. bras. nefrol; 41 (3), 2019
Abstract Introduction: Arteriovenous fistulas (AVF) are the best hemodialysis vascular accesses, but their failure rate remains high. Few studies have addressed the role of the vascular surgeon's skills and the facility's practices. We aimed to study these factors, with the hypothesis that the surgeon's...

Effect of local papaverine on arteriovenous fistula maturation in patients with end-stage renal disease

J. bras. nefrol; 41 (2), 2019
Abstract Background: Arteriovenous fistula (AVF) maturation is one of the main concerns in patients with end-stage renal disease (ESRD) and finding a strategy for increasing success rate and accelerating fistula maturation is valuable. The aim of this study was to evaluate the effects of papaverine inje...

Evaluation of variables associated with the patency of arteriovenous fistulas for hemodialysis created by a nephrologist

J. bras. nefrol; 40 (4), 2018
ABSTRACT Introduction: Arteriovenous fistula (AVF) is considered the gold standard vascular access for chronic hemodialysis, and its failure predicts higher morbidity and mortality rates. Objective: 1) To evaluate the success rate of AVF created by a nephrologist and 2) to identify clinical, laboratory...

Salvage of thrombosed arteriovenous fistulae of patients on hemodialysis: report on the experience of a Brazilian center

J. bras. nefrol; 40 (4), 2018
ABSTRACT Introduction: Hemodialysis vascular access thrombosis is an acute event that can interrupt the dialytic treatment. A timely management can restore access patency, avoiding the use of central venous catheters and their complications. Objective: To present the experience from a Brazilian Interve...

Are high flow arteriovenous accesses associated with worse haemodialysis?

J. bras. nefrol; 40 (2), 2018
ABSTRACT Introduction: An arteriovenous (AV) access flow (Qa) of 400 mL/min is usually sufficient for an effective hemodialysis (HD), but some accesses continue developing and become high flow accesses (HFA). Some authors postulated that an HFA might shift a significant portion of dialyzed blood from th...

Transcatheter closure of perimembranous ventricular septal defects in children using a Wire-Drifting Technique

Clinics; 73 (), 2018
OBJECTIVE: Explore the feasibility and safety of transcatheter closure of perimembranous ventricular septal defects using a wire-drifting technique (WT) in children. METHODS: We retrospectively analyzed 121 pediatric patients diagnosed with perimembranous ventricular septal defects who underwent interve...
