DialyseGrafts

DialyseGrafts, also known as arteriovenous grafts (AVGs), are synthetic tubes used to create access to the bloodstream for hemodialysis. They are an alternative for patients whose blood vessels are not suitable for an arteriovenous fistula (AVF). An AVG is surgically placed under the skin, connecting an artery to a vein. The synthetic material, typically made of expanded PTFE (ePTFE), allows blood to flow from the artery, through the graft, and into the vein, creating a loop that can be accessed by needles for dialysis treatments.

The placement of a DialyseGraft involves a minor surgical procedure. The surgeon makes an incision, inserts the graft, and connects its ends to the artery and vein. The graft then matures for a period, usually a few weeks, before it can be used for dialysis. During dialysis, two needles are inserted into the graft. One needle draws blood from the graft to be filtered by the dialysis machine, and the other needle returns the cleaned blood back into the body through the graft.

DialyseGrafts offer a faster access route compared to AVFs, which can be advantageous for patients who cannot wait for an AVF to mature. However, they also carry a higher risk of complications such as infection, thrombosis (blood clotting), and stenosis (narrowing of the graft). Regular monitoring and proper care are essential to maintain the function of a DialyseGraft and prevent complications. Patients with DialyseGrafts require diligent hygiene practices and prompt reporting of any signs of infection or malfunction.
