Vascular Access

The arteriovenous (AV) fistula is considered the best long-term vascular access for hemodialysis because it allows good blood flow, lasts a long time, and is less likely to get infected or cause blood clots than other types of access. Patients who don't have time to get a permanent vascular access before they start hemodialysis treatments may need to use a venous catheter as a temporary access.
