OBJECTIVE
The arteriovenous fistula (AVF) is the preferred hemodialysis access. Subset analyses of both the HEMO and DOPPS studies have shown that obese hemodialysis patients have a lower prevalence of functioning AVF. Doppler ultrasound may increase the prevalence of functioning AVF in obese
OBJECTIVE
Successful arteriovenous fistula (AVF) maturation is often challenging in obese patients. Optimal initial intraoperative blood flow (IOBF) is essential for adequate AVF maturation. This study was conducted to elucidate the effect of obesity on IOBF and radiocephalic AVF
BACKGROUND
Obesity, which is often associated with diabetes, is increasingly encountered in the haemodialysed population, and this may produce difficulty in autogenous arteriovenous fistula creation. Prosthetic angioaccess or catheters, when used in place of autogenous fistulas, increase thrombotic
BACKGROUND
Obesity in the hemodialysis population is roughly twice that of the general population. An arteriovenous fistula (AVF) remains the recommended vascular access; however, obesity results in fewer autogenous accesses, more complexity, and higher AVF failure rates. We reviewed our vascular
BACKGROUND
In obese patients with end stage renal disease, puncturing matured arteriovenous fistulas (AVF) that run deep under the skin surface may prove difficult. To achieve reliable puncturability, there are several surgical solutions. Superficialization with mobilization is common. With some
Fistula use for dialysis is less frequent among obese than non-obese patients. This discrepancy may be due to a lower rate of fistula placement in obese patients, a higher primary failure rate (fistulas that are never usable for dialysis), or a higher secondary failure rate (fistulas that fail after
The aim was to evaluate the safety and feasibility of endoscopic superficialisation (ES) in patients with deeply located cephalic veins in well matured arteriovenous fistulae (AVF) and to present functional outcomes.All patients with cannulation The two main factors leading to a functional fistula are maturity and accessibility. The aim of this review was to describe a technique of superficialization for inaccessible brachiocephalic fistulas, and to identify the patients that benefit from superficialization. One hundred and thirty-two
Spinal dural arteriovenous fistulas (AVFs) frequently cause progressive myelopathy. When they are localized by imaging studies, surgery can be safely performed by simply interrupting the vein draining the fistula intradurally, and the results will be excellent and lasting. In some patients with
OBJECTIVE
The standard lengthy surgical incision used for basilic vein arteriovenous fistula (AVF) transposition is associated with significant discomfort, scarring and risk of wound complications. Minimally invasive vein dissection using a laryngoscope is an inexpensive alternative which has been
Prader-Willi syndrome is characterized by infantile hypotonia, childhood-onset obesity, short stature, mental retardation, hyperphagia, hypogonadism. After infantile hypotonia phase, patient is prone to morbid obesity due to hyperphagia. Complications associated with morbid obesity are recognized as
BACKGROUND
Observation versus ligation of a functional arteriovenous fistula (AVF) after successful renal transplantation (SRT) has been a controversial topic of debate. Congestive heart failure and pulmonary hypertension are common in dialysis patients, and more frequent when vascular access flow
We report a novel method to provide excellent anatomical depiction of a dural arteriovenous fistula (dAVF) for surgical planning.A 78-year-old female presented with progressive back pain, deteriorating mobility and urinary incontinence with a background of The incidence of iatrogenic femoral arteriovenous fistulas (IFAVF) has increased in contemporary practice. We herein report the case of a 55-year-old obese woman with significant surgical comorbidities who sustained an IFAVF between the superficial femoral artery (SFA) and the femoral vein. Given
