Platelet-rich plasmapheresis

Platelet-rich plasmapheresis is technique used mostly in cardiac surgery that involves a patient's own blood. The platelet-rich plasma is withdrawn into a plasmapheresis device. This can be either performed pre-operatively (within 24 hours of surgery) or intra-operatively. The platelet rich plasma is returned to the patient at the end of the surgery (usually after protamine infusion). The transfusion of the patient with a highly concentrated and platelet-rich product derived from their own blood reduces the need for transfusion of blood. But is an expensive and time consuming technique and not widely used.
