Duplex sonography recently has been recognized as an objective and noninvasive method to assess morphological and functional parameters of vessels that could predict arteriovenous fistula (AVF) patency and time of adequate maturation. To prospectively study prognostic indicators of native AVFs, forearm arteries and veins of patients with end-stage renal(More)

PURPOSE The prospective study was aimed at estimating the value of duplex sonography for imaging arteries before arteriovenous fistula (AVF) construction and of evaluating the influence of this method on the outcome of fistula construction. METHODS A total of 35 patients with end stage renal disease were examined by duplex sonography (DS) before AVF(More)
Patients presenting for initial access evaluation in contemporary practice are less likely to have arteries and veins suitable for native fistula (AVF) formation in the classic location. Physical examination of the upper extremity alone may be inadequate for selection of arteries and veins that will mature into a functioning AF. The purpose of this paper is(More)

Vascular access management is central to maintain the health and quality of life of end-stage renal disease (ESRD) patients. Early referral to a nephrologist for a decision about replacement therapy, preservation, clinical evaluation of vessels and planning for timely placement of an arteriovenous fistula (AVF) should be done. The number of patients with(More)
The long-term survival and quality of life of patients on hemodialysis is dependent on the adequacy of dialysis via an appropriately placed vascular access. Recent clinical practice guidelines recommend the creation of native arteriovenous fistula or synthetic graft before start of chronic hemodialysis therapy to prevent the need for complication-prone(More)
Non-maturation is a feature of autologous vascular access. The autologous arteriovenous fistula needs time to mature and for the vein to enlarge to a size where it can be needled for dialysis. A fistula that fails early is one that either never develops adequately to support dialysis or fails within the first three months of its use. Two variables are(More)
BACKGROUND Vascular access is "the life line" for patients on chronic hemodialysis. The autogenous arteriovenous fistula provides the best access to the circulation because of low complication rate, long-term use, and lower cost, compared to arteriovenous graft and central venous catheter. The primary objective of this prospective study was to investigate(More)
