The method involves the use of a special, semi-rigid, plastic catheter tube to achieve better flow rates at a time when other methods are ineffective.

What is the difference between a fistula and a graft?

A fistula is created between an artery and a vein. The fistula is a permanent route to the bloodstream. There are two types of fistulas: AV fistulas and AV grafts.

What is the process of hemodialysis?

Hemodialysis and hemodiafiltration. The processes of hemodialysis, hemofiltration, and hemodiafiltration involve removal of the patient’s blood from the systemic circulation, removing the patient’s blood, and returning the blood to the systemic circulation.

Blood flows from the body (the body) directly inside the body (fistula) to the dialysis machine (vein). The body doesn’t need two fistula openings. If you have two fistula openings, you can use both for dialysis.

Additionally, what vessels are used for AV fistula?

The vessels used for AVF and grafts. AV fistulas are placed in the groin area via the femoral artery or vein. AV grafts are placed in the arm via the brachial artery or vein. Both the arteries and veins are used because the larger size of these vessels makes it easier for them to be punctured.

Can a fistula burst?

Fistulas in the perianal region are rare. However, when they do occur, they can be quite painful, but only in the initial diagnosis phase and before treatment with systemic antibiotics.
