Duplex ultrasound evaluation for dialysis access selection and maintenance: a practical guide.
Detailed case directed history and examination is the mainstay of dialysis access modality selection, ie site and type of access, as well as for maintenance of dialysis access for longevity. As a logical step following history and physical examination, duplex ultrasound evaluation (DUE) is the most cost effective and non-invasive screening tool for evaluation for access placement and for assess...
متن کاملThe Usefulness of Duplex Ultrasound for Hemodialysis Access Selection
PURPOSE A native vessel is preferable to an artificial graft for dialysis access. Duplex ultrasound (DUS) is noninvasive, cost-effective modality to evaluate the vessels for dialysis. The purpose of this study was to compare the rates of utilization of native vessels after preoperative imaging with DUS and contrast venography (CV). MATERIALS AND METHODS A retrospective review was performed on...
متن کاملDuplex ultrasound scanning of the autogenous arterio venous hemodialysis fistula: a vascular surgeon's perspective
Introduction Duplex ultrasound has become the first line of investigation for the autogenous arterio-venous hemodialysis fistula (aAVF). In recent work published by our group, we showed that duplex ultrasound was as accurate as fistulography in the assessment of fistula stenoses. The emergence of duplex ultrasound as the primary tool for examination of the aAVF is the result of better technolog...
متن کاملEffect of combination of alcohol and Betadine on the severity of inflammation in the vascular access site in hemodialysis patients
Background: Inflammation in the vascular access site results in infection, which is the second leading cause of death in hemodialysis patients. However, there is no specific protocol available for sterilization before vascular access in such patients. Aim: to determine the effect of the combination of alcohol and Betadine on the severity of inflammation in the vascular access site in hemodialys...
