Vascular access in therapeutic apheresis: One size does not fit all.

PVA has been promoted in recent years in many centers across the United States to lower the rate of complications associated with vascular access and to make this procedure more accessible. Several factors are involved in selecting appropriate venous access, such as the procedure's duration and frequency, patient's vascular anatomy, and staff's experience. In short-term procedures, temporary vascular access like PVA or CVC is preferred. Permanent vascular access such as AVF, tunneled cuffed central lines, and implantable ports are more beneficial in prolonged treatment period but each patient has to be evaluated individually by apheresis team for the most appropriate method.
