What is a graft in the context of hemodialysis?

In the context of hemodialysis, a graft refers to a surgical connection that links an artery and a vein using a piece of an artificial blood vessel, typically made from synthetic material. This procedure is performed to create a vascular access point for dialysis treatment.

The graft serves as a means to facilitate blood flow during hemodialysis sessions, allowing the blood to be drawn from the body, purified through the dialysis machine, and then returned. The use of a graft is particularly beneficial for patients whose veins may not be suitable for direct puncture or for those who have exhausted other access options.

Understanding this definition is crucial, as it highlights the significant role of grafts in ensuring effective and reliable vascular access for patients undergoing hemodialysis therapy, thereby improving treatment outcomes and patient safety.
