BACKGROUND The aim of this study was to examine the effect of ethnicity, socioeconomic group (SEG) and comorbidities on provision of vascular access for haemodialysis (HD). METHODS This was a retrospective review of two databases of HD sessions and access operations from 2003-11. Access modality of first HD session and details of transplanted patients were derived from the renal database. Fol...

PURPOSE The classic symptoms and signs of carotid cavernous sinus fistula or cavernous sinus dural arteriovenous fistula (AVF) consist of eye redness, exophthalmos, and gaze abnormality. The angiography findings typically consist of arteriovenous shunt at cavernous sinus with ophthalmic venous drainage with or without cortical venous reflux. In rare circumstances, the shunts are localized outsi...

BACKGROUND Arteriovenous fistula (AVF) failure is a significant cause of morbidity and expense in patients on maintenance haemodialysis (HD). Circulating biomarkers could be valuable in detecting patients at risk of AVF failure and may identify targets to improve AVF outcome. Currently there is little consensus on the relationship between circulating biomarkers and AVF failure. The aim of this ...

BACKGROUND Maintenance of adequate vascular access for hemodialysis is important in patients with end-stage renal disease. Once arteriovenous fistula (AVF) occlusion occurs, the patient should be treated with rescue therapy. This study was performed to evaluate the results of a rescue therapy for AVF occlusion. METHODS From January 2008 to December 2012, 47 patients who underwent surgical res...

BACKGROUND AND OBJECTIVES Arteriovenous fistulas (AVFs) remain the preferred vascular access for hemodialysis patients. Dialysis facilities that fail to meet Centers for Medicare & Medicaid Services goals cite patient case-mix as a reason for low AVF prevalence. This study aimed to determine the magnitude of the variability in AVF usage across dialysis facilities and the extent to which patient...

Transient faults can lead to serious errors in execution. Providing protection for the processor core against these faults requires redundant execution, which leads to a performance loss. However, not all bit flips have equal impact on the processor. The Architectural Vulnerability Factor (AVF) quantifies when a soft error is likely to alter the final output and when it has little impact due to...

1 ABSTRACT Arteriovenous fistula (AVF) maturation failure is mainly due to venous stenosis characterized by significant amount of intima-media thickening (IMT). Although hemodynamic endpoints are believed to play a crucial role in pathogenesis of venous stenosis, the exact mechanism behind this is unclear. Our hypothesis is that longitudinal (temporal) changes of hemodynamic parameters, specifi...

Transitional flow within an arteriovenous fistula (AVF) leads to vascular disease, which can be treated by implanting a stent. Large Eddy Simulations of blood patient-specific AVF revealed the significantly higher turbulent behavior in Stent-absent when compared Stented AVF. This finding provides key understanding reasons behind success this treatment strategy from fluid dynamics perspective.
