[Aorto-coronary bypass grafting in a patient with neutrocytopenia].

A 71-year-old woman with neutrocytopenia (690/mm3) was treated with prednisolone before coronary surgery. After the normalized hemogram with increased leukocyte counts, aorto-coronary bypass grafting with saphenous vein was performed for left main trunk disease. Her convalescence was quite stable without any infectious or adrenal problems. It was meaningful to treat neutrocytopenia with steroids in order to predict the hematological reaction to stress before the operation.
