The number of patients with chronic kidney disease re-quiring renal replacement therapy has increased world-wide. The most common replacement therapy is hemo-dialysis （HD）. Vascular access （VA） has a key role for successful treatment. Despite the advances that have taken place in the feld of the HD procedure, few things have changed with regards to VA in recent years. Ar-teriovenous fstula （AVF）, polytetrafuoroethylene graft and the cuffed double lumen silicone catheter are the most common used for VA. In the long term, a number of complications may present and more than one VA is needed during the HD life. The most common com-plications for all of VA types are thrombosis, bleeding and infection, the most common cause of morbidity in these patients. It has been estimated that VA dysfunc-tion is responsible for 20% of all hospitalizations. The annual cost of placing and looking after dialysis VA in the United States exceeds 1 billion dollars per year. A good functional access is also vital in order to deliver adequate HD therapy. It seems that the native AVF that Brescia and Cimino described in 1966 still remains the frst choice for VA. The native forearm AVFs have the longest survival and require the fewest interventions. For this reason, the forearm AVF is the frst choice, fol-lowed by the upper-arm AVF, the arteriovenous graft and the cuffed central venous catheter is the final choice. In conclusion, VA remains the most importantissue for patients on HD and despite the technical im-provements, a number of problems and complications have to be resolved.
