Successful long‐term erythrocytapheresis therapy in a patient with symptomatic sickle‐cell disease using an arterio‐venous fistula

Abstract

The use of long-term automated erythrocytapheresis via an arterio-venous fistula for the prevention of recurrent ischaemic stroke in a child with sickle-cell disease (SCD) has not been described previously. We report the successful use of this technique in a 13-year-old boy. A procedure was performed every 36 +/- 6 days, transfusing six units of donor packed red blood cells (RBCs) and discarding 1318 +/- 174 mL of exchanged erythrocytes (Hct 60%). After transfusion of 85 units over 17 months, there is no evidence for iron-overload, red cell alloimmunization, transfusion-transmitted infections, or other complications. Until now, no cerebrovascular ischaemia has been observed.
