Before starting hemodialysis, a direct access to bloodstream should be developed through surgery. There are a few ways to create such access. The first one is Fistula, a.k.a. arteriouvenous fistula or A-V fistula. Fistula could be created is because an artery and vein are joined together under the skin in arm. Employing this method, it will take 6 weeks or longer to heal before hemodialysis could be conducted. However, once fistula is created, it could be used for many years. The second one is Graft, a.k.a. arteriovenous graft or A-V graft. A plastic tube is used to join an artery and vein under skin. This method could be employed if patients need to start hemodialysis quickly. Because Only 2 weeks are needed to heal when minor surgery is done to create the access of graft. But patients may need to replace the graft after a few years. The third one is Catheter (central venous catheter). If patient needs to start hemodialysis very quickly, catheter could be employed.
