From the Department of Cardiovascular Surgery Yokohama National Hospital, Yokohama, Kanagawa, Japan
A 76-year-old female with chronic idiopathic thrombocytopenic purpura required coronary bypass grafting. Preoperative treatment with high-dose intravenous immunoglobulin at a dose of 0.4 g/kg/day raised the platelet count from 57,000 to 110,000/µL. After termination of cardiopulmonary bypass (CPB) the residual blood in the CPB circuit was washed to reduce total immunoglobulin G (IgG) level, including platelet-associated immunoglobulin G (PA-IgG), and returned to the patient. Intraoperative platelet transfusion was used due to a drop in platelet count to the pretreatment level. The postoperative level of IgG and PA-IgG remained significantly lower than preoperatively. The postoperative course was uneventful and without bleeding complications. Perioperative management of a patient with idiopathic thrombocytopenic purpura undergoing open-heart surgery is discussed.
