Vascular access in hemodialysis patients is crucial. Vascular access monitoring to ensure access patency is important for patient survival, quality of life, and blood vessel care. The ultrasound dilution method for measuring access flow is a screening tool to assess access dysfunction. Park et al. [1] performed a single-center prospective study of the variation in access flow during hemodialysi...

The vascular access serves as the “lifeline” for the hemodialysis patient, but in recent years has become the “Achilles Heel” of the hemodialysis procedure. The vascular health of the vessels used to create arteriovenous accesses is paramount to vascular access maturation and successful outcomes. Vascular calcification is widely present in the vessels of chronic kidney disease (CKD) and end sta...

INTRODUCTION. Arteriovenous fistulas and grafts are two common permanent access methods for hemodialysis. Selection of an appropriate access, appropriate surgical techniques, and treatment of complications are basic principles of long-term maintenance of vascular access. We aimed to assess the survival of arteriovenous fistulas and grafts in our dialysis center. MATERIALS AND METHODS. A total o...

Failure of hemodialysis access is caused mostly by venous intimal hyperplasia, a fibro-muscular thickening of the vessel wall. The pathogenesis of venous neointimal hyperplasia in primary arteriovenous fistulae consists of processes that have been identified as upstream and downstream events. Upstream events are the initial events producing injury of the endothelial layer (surgical trauma, hemo...
