[A case of ASD with SLE treated with Carmeda BioActive surface circuit in cardiopulmonary bypass system].

A 61-year-old woman of ASD complicated with SLE was operated on. We used a heparin coating Carmeda BioActive Surface (CBS) in cardiopulmonary bypass circuit for the purpose to prevent the postoperative complications due to the reduced complement activation by SLE. This system could prevent the decline of the reduced complement activation during cardiopulmonary bypass and after operation. The management of steroid therapy for SLE patient, usefulness of heparin coating CBS system for hypocomplement disease were discussed.
