Where do you Cannulate an AVF?
Guidelines describe three possible ways to cannulate an AVF: rope ladder (RL), area puncture (AP), and buttonhole (BH). When using RL, the cannulator creates a new puncture site each time. The puncture site is placed 0.5 cm from the last puncture site and the whole length of the AVF is used.
What is AVF insertion?
An AV fistula is how patients are connected to a dialysis machine. A nurse starts your dialysis treatment by inserting two needles into the AV fistula. One needle removes the blood and sends it to the machine, where it is filtered. The second needle allows the blood to be safely returned to the body.
What is the use of AVF?
An arteriovenous (AV) fistula is a connection, made by a vascular surgeon, of an artery to a vein. Provides good blood flow for dialysis. Lasts longer than other types of access. Is less likely to get infected or cause blood clots than other types of access.
What are the different types of AVF?
There are 3 basic types of AVF dialysis:
- Radial Cephalic fistula.
- Brachial Cephalic.
- Brachial Basilic Transposition.
What is cannulation of a fistula?
The buttonhole technique is a way to “cannulate,” which means “to insert dialysis needles.” Instead of sharp, pointed needles, dull needles are placed into the exact same holes on your fistula every time you have dialysis. Inserting the needles in the same holes creates a “tunneled track” for the needle.
What is a fistula cannula?
The other needle option is known as a “fistula cannula,” “fistula catheter,” or “plastic” needle that is designed specifically for hemodialysis cannulation. The basic design is a sharp metal needle housed within a flexible plastic sheath.
What is AVF surgery?
An arteriovenous graft is another form of dialysis access, which can be used when people do not have satisfactory veins for an AV fistula. In this procedure, surgeons connect an artery and a large vein in your elbow or armpit using a graft made of synthetic fabric that is woven to create a watertight tube.
What is an AVF Needle?
Nipro’s standard AVF needles are designed to minimize vessel trauma and optimize blood flow: ultra-sharp, siliconized 3-bevel needle with ultra-thin wall. Nipro takes every effort to provide a safe, long-lasting vascular access for hemodialysis patients.
Is AVF a central line?
AVF is an uncommon complication of central venous catheterization that can have serious complications [8,9]. The exact pathophysiology of AVF formation is unclear, but previous proposed mechanisms have focused on damage to adjacent arteries at the time of TCC insertion [4,7].
Which veins are used for cannulation?
The preferred sites for IV cannulation
- Hand. Dorsal arch veins.
- Wrist. Volar aspect.
- Cubital fossa. Median antecubital, cephalic and basilic veins.
- Foot. Dorsal arch.
- Leg. Saphenous vein at the knee.
What is AVF needle?
A.V. FISTULA NEEDLE SET. Needles for use in patients on haemodialysis. Needles for use in patients, silicone tipped needle for atraumatic insertion. Back eye for uninterrupted blood flow through the needle. Rotable wings for firm grip, easy turning and secure fixation.

What is AVF medical?
An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein. When there is a fistula in the brain, we call it an arteriovenous malformation (AVM).
