Did they make a fistula by putting a vein and an artery together or did they put a Shiley or Groshong catheter (central line) in?
Here is how a fistula is made:
Creating the access portal is a minor surgical procedure. There are two types of portals placed completely under the skin:
- Fistula, which your vascular surgeon constructs by joining an artery to a vein.
- Graft, which is a man-made tube, consisting of a plastic or other material, that your vascular surgeon inserts under the skin to connect an artery to a vein.
efficiently.In the weeks after surgery, the fistula begins to mature. The vein increases in size and may look like a cord under your skin. The whole process of maturation, which is a beneficial feature that permits the blood flow to increase in the fistula, typically takes 3 to 6 months. Some fistulas may take as long as a year or more to develop fully, but this is unusual. Once matured, a fistula should be large and strong enough for dialysis technicians and nurses to insert the large dialysis needles easily. If it fails to mature in a reasonable period of time, however, you may need another fistula.
You can usually begin using your graft in 2 to 6 weeks, when it is healed sufficiently. Usually fistulas are preferred to grafts, however, because fistulas are constructed using your own tissue, which is more durable and resistant to infection than are grafts. However, if your vein is blocked or too small to use, the graft provides a good alternative.
