The challenging surgical vascular access creation

Abstract

With the increasing life expectancy of patients with end-stage kidney disease, the creation and maintenance of hemodialysis vascular access are becoming more challenging. A comprehensive patient evaluation including a complete history, physical examination, and ultrasonographic vessel assessment is the foundation of the clinical evaluation. A patient-centered approach acknowledges the myriad of factors that impact the selection of optimal access for the distinct clinical and social circumstance of each patient. An interdisciplinary team approach involving various healthcare providers in all stages of hemodialysis access creation is important and associated with better outcomes. While patency is considered the most important parameter in most vascular reconstructive scenarios, the ultimate determinant of success in vascular access for hemodialysis is a circuit that allows consistent and uninterrupted delivery of the prescribed hemodialysis. The best conduit is one that is superficial, easily identified, straight, and of a large caliber. Individual patient factors and skill level of the cannulating technician also play a crucial role in the initial success and maintenance of vascular access. Special attention should be considered in dealing with more challenging groups such as the elderly population where the newest vascular access guidance from The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative will be transformative. The current guidelines recommend monitoring the vascular access by regular physical and clinical assessments, however, inadequate evidence is available to support routine ultrasonographic surveillance for improving access patency.
