Vascular access

Ultrasound is the standard of care for guiding insertion of dialysis catheters. This is a simple, easily learned procedure that enable nephrologists to insert dialysis catheters and expedite patient care.

​Sonography of AV grafts and fistulas is essential for evaluating dysfunction and poor maturation and that can be performed by nephrologists at the point of care. It is also an important tool for guiding cannulation for dialysis. Point-of-care sonography expedites patient care and leads to better management and outcomes of vascular access.
