emodialysis, is the most often used treatment for end-stage renal disease(ESRD), more commonly known as kidney failure. During a hemodialysis
treatment, a machine pumps blood from your body by way of a flexible,
plastic tube, cleans it and then returns it to your body through a separate
tube. In order to perform hemodialysis, an access must be created. An
access is a site from which blood can be safely removed and returned to
your body. The access site is often referred to as your "lifeline."
There are two types of dialysis accesses. The first kind involves the creation
of a permanent connection between an artery and a vein under the skin. The
two kinds of permanent accesses, fistulas and grafts, are used for patients
with renal failure who are expected to need long-term dialysis treatment.
Fistulas and grafts are usually placed in the arm, but they may also be
placed in the leg. They are surgically placed a few months before dialysis
is scheduled to begin in order to allow for the site to heal and develop
properly.
The other type of access involves the direct placement of a tube into
a large vein in the neck, chest or groin. As described in this brochure,
catheters are most appropriately reserved for patients needing short-term
dialysis or patients on long-term dialysis who no longer have a place to
insert a fistula or graft.............................
