Treatment of hemodialysis vascular access arteriovenous graft failure by percutaneous intervention.

A patent vascular access is the lifeline of end-stage renal disease patients depending on hemodialysis treatment. Once a functioning vascular access has been established, maintaining its patency is of utmost importance. During the last decades percutaneous techniques became increasingly important for the treatment of hemodialysis vascular access graft failure.

Experimental study of a new method for early detection of vascular access stenoses: pulse pressure analysis at hemodialysis needle.

Hemodialysis vascular access (VA) stenosis remains a frequent complication. However, early detection is challenging and costly. The aim of this in vitro study was to assess a new detection method based on pulse pressure analysis at the hemodialysis needle.
