How is arteriovenous fistula (AVF) bleeding treated?
· If bleeding Continues… If cannot control with above Then have “helper” apply pressure proximal and distal to punctate bleed. This will reduce arterial and venous flow to the fistula, and stop bleeding. This will allow you to apply “topical meds” (e.g. TXA, Gelfoam). see example of helper in “Real life example video” below Figure of 8 Suture
How do you stop a fistula from bleeding?
An AV fistula is an abnormal connection between an artery and a vein, and is sometimes surgically created to help with haemodialysis treatment. In these cases, a shunt graft is inserted to aid the treatment. Unfortunately, sometimes the shunt will fail, known as graft malfunction. If you experience this, your doctor may recommend that you have endovascular treatment.

What is the best treatment for stenosis?
If you have a stenosis (narrowing), the best treatment option is a balloon which can be inserted and gently inflated, while if you have a blood clot, a combination of thrombectomy, thrombolysis and medication to prevent blood clotting may be recommended.
Can a graft block blood flow?
Blood clots may form and block the flow of blood through the access site. Grafts and catheters are more likely than fistulas to clot. The blood vessels in your graft or fistula can become narrow and slow down the flow of blood through the access. This is called stenosis.
What is the vascular access for hemodialysis?
Know What Type of Vascular Access You Have. There are 3 main types of vascular accesses for hemodialysis. These are described as follows. Fistula: An artery in your forearm or upper arm is sewn to a vein nearby. This allows needles to be inserted into the vein for dialysis treatment.
What is vascular access?
Expand Section. A vascular access is an opening made in your skin and blood vessel during a short operation. When you have dialysis, your blood flows out of the access into the hemodialysis machine. After your blood is filtered in the machine, it flows back through the access into your body.
