Hemodialysis is the most common type of dialysis. It might work well for you. If so, you probably would go to a dialysis center, usually 3 times a week. Or you would go for your hemodialysis at night, usually 5-6 times a week. In hemodialysis, a dialysis machine and a special filter called an artificial kidney, or a dialyzer, are used to clean your blood. To get your blood into the dialyzer, the doctor needs to make an access, or entrance, into your blood vessels. Choosing Your Vascular AccessAs you may know, vascular access means reliable sites, usually on arms and legs, where the bloodstream can be easily accessed. An important part of your hemodialysis treatment is choosing your vascular access. Of the three options for vascular access, Arteriovenous Fistula (AVF) is the best choice for most people. The other two options are using a catheter or an Arteriovenous Graft (AVG). What is a fistula and how does it work? A provider explains the purpose, process, and benefits of Arteriovenous Fistula (AVF) surgery. Your Access to Success: Dialysis patients explain the benefits of dialyzing with an AVF.
