Cardiopulmonary Bypass Strategy for a Cyanotic Child With Hemoglobin SC Disease.

Hemoglobin SC (HbSC) disease is a hemoglobinopathy that may produce sickling under conditions of hypoxemia, dehydration, and acidosis. We present a case of HbSC disease and tricuspid atresia, type IB. We describe management by cardiopulmonary bypass CPB using exchange transfusion at initiation of bypass and fractionation of collected blood, allowing platelet and plasma apheresis, as an option for patients unable to undergo this procedure off pump.
