How you prepare
By Mayo Clinic staffPreparation for hemodialysis starts several weeks to months before your first procedure. To allow for easy access to your bloodstream, a surgeon will create a vascular access, usually referred to as an access. It is the place on the outside of your body where blood is removed for hemodialysis and then returned. The surgical access needs time to heal before you begin hemodialysis treatments.
Three types of accesses are used:
- Arteriovenous (AV) fistula. A surgically created AV fistula is a connection between an artery and a vein, usually in the forearm of your nondominant arm. This is the preferred type of access.
- AV graft. If your blood vessels are too small to form an AV fistula, the surgeon may instead create a path between an artery and a vein using a flexible, synthetic tube called a graft, sometimes called a synthetic bridge graft.
- Central venous catheter. If you need emergency hemodialysis, the surgeon may insert a plastic tube (catheter) into a large vein in your neck or near your groin. The catheter is temporary.
