[Serum immune complexes and cardiopulmonary bypass. A review of thirty-four cases (author's transl)]. / Immuns complexes circulants et circulation extra-corporelle. A propos de trente-quatre cas.

The immunologic status of patients undergoing cardiopulmonary bypass as investigated. Rheumatoid factor, cryoglobulinemia and serum immune complexes were looked for. Studies were performed before the operation and eight or fifteen days later. From the results, it is concluded that the immunologic changes that occur in the immediate postoperative period cannot be interpreted because of the profound modifications resulting from cardiopulmonary bypass.
