What is a second stage Brachiobasilic fistula?

The second stage ‘superficialization’ was carried out at a median (range) of 73 days (32-1827 days) after fistula formation and involved mobilizing the arterialized basilic vein through a curved longitudinal incision on the anteromedial aspect of the arm and transposing it beneath the skin incision.

What is a second stage Brachiobasilic fistula?

The second stage ‘superficialization’ was carried out at a median (range) of 73 days (32-1827 days) after fistula formation and involved mobilizing the arterialized basilic vein through a curved longitudinal incision on the anteromedial aspect of the arm and transposing it beneath the skin incision.

What is a brachiocephalic fistula?

The brachiocephalic fistula (Fig. 4) is an up- per arm fistula created by connecting the side of a brachial artery to the end of a cephalic vein at or slightly central to the level of the elbow.

What is a second stage AV fistula?

The second stage is performed 4–12 weeks later and involves the creation of a superficial lateral tunnel. The now arterialised basilic vein is transposed and re-anastomosed to the brachial artery. An alternative approach is to superficialise the fistula without re-anastamosis.

What is a transposed fistula?

The arteriovenous fistula transposition is based on a first-stage proximal radial artery to median cubital vein arteriovenous fistula. Transposed brachial veins were elevated and positioned anteriorly to the incision to avoid repeated needle access through the surgical scar (Fig 2).

Why is AV fistula created?

Arteriovenous fistulas are often surgically created for use in dialysis in people with severe kidney disease. A large untreated arteriovenous fistula can lead to serious complications. Your doctor monitors your arteriovenous fistula if you have one for dialysis.

Why do we create AV fistula for dialysis?

An AV fistula causes extra pressure and extra blood to flow into the vein, making it grow large and strong. The larger vein provides easy, reliable access to blood vessels. Without this kind of access, regular hemodialysis sessions would not be possible.

How is a fistula made for dialysis?

An AV fistula is a connection that’s made between an artery and a vein for dialysis access. A surgical procedure, done in the operating room, is required to stitch together two vessels to create an AV fistula.

What are common sites for fistula placement?

The three most common AVFs are the radiocephalic fistula, the brachiocephalic fistula, and the brachial artery-to-transposed basilic vein fistula. Although many potential access site stenoses can and do occur within any given fistula, each fistula has a characteristic site of stenosis.

What is stage1 fistula?

The one-stage procedure aims to create a fistula between the basilic vein and the brachial artery in the upper arm in one procedure. This would require a long incision to gain access and mobilise the basilic vein making sure the anastomosis is not placed under tension and no obvious stenosis is present proximally.

What is Superficialization of AV fistula?

‘Superficialization’ or ‘fistula elevation’ involves an incision from the wrist to the proximal forearm in radiocephalic fistulas, and from the antecubital fossa to the proximal upper arm in brachiocephalic or brachiobasilic fistulas.
