Abstract
Summary: Most patients with DiGeorge syndrome require surgery to their heart defect during infancy and are at risk of developing transfusion-associated graft-versus-host disease if non-irradiated blood is used perioperatively. Because of its wide clinical variability, DiGeorge syndrome may not be recognized before surgery and thus a high level of vigilance is required. An infant is described who developed fatal graft-versus-host disease after receiving non-irradiated blood components during surgery for classical tetralogy of Fallot; the postoperative clinical course and autopsy findings were consistent with underlying DiGeorge syndrome. An informal survey of the 18 pediatric cardiology units in the United Kingdom and the Republic of Ireland showed no consensus as to which patients should be screened for DiGeorge syndrome, which screening test to use and to whom irradiated blood components should or should not be given to prevent transfusion associated graft-versus-host disease. Assessment of T-cell numbers appears to be the preferred screening method to determine those who might benefit from receiving such therapy.Keywords
