AV Graft for Dialysis

• For creation of a forearm loop

AVG

• Subcutaneous tunnels are

created by curved metal

tunnellers
• PTFE graft is passed into

the lumen of the

tunnellers
• Once the metal tunnellers

are removed, the graft is

placed at the
subcutaneous level for

future HD punctures

This is a patient undergoing brachio-cephalic AVG creation for long term haemodialysis.
Incision is made over the antecubital fossa.

Brachial artery (slung in red) and cephalic vein (slung in blue) are identified

AV graft (AVG) creation is considered when:

1. No good quality superficial veins identified on USG

(e.g. small, deep and tortuous veins)

2. A quick access is required (AVF needs time to mature)
