Cardiac Perioperative Management of Patients with DiGeorge Syndrome Undergoing Surgery

Objective: DiGeorge syndrome is a genetic disorder with multisystem involvement resulting in craniofacial and cardiac anomalies and parathyroid and immune system dysfunction. This study describes perioperative management of a large cohort of patients with DiGeorge syndrome undergoing cardiac surgery. Design: Retrospective cohort study. Setting: Major academic tertiary institution. Participants: The medical records of patients diagnosed with DiGeorge syndrome and undergoing cardiac surgery at this institution, from January 1, 1976, to July 31, 2012, were reviewed for phenotypic characteristics and intraoperative and postoperative complications, with specific attention to hemodynamic instability, perioperative perturbations of plasma calcium homeostasis, and airway difficulty. Interventions: None. Measurements and Main Results: Sixty-two patients underwent 136 cardiac surgical procedures; 47 patients (76%) had multiple operations. Sternotomies for reoperations often were complex (8 complicated by vascular injury or difficulty achieving hemostasis and 5 requiring bypass
