Re-operative surgery in pediatric patients

Abstract

In spite of recent emphasis on primary repair for congenital heart defects, multiple operations are often required for staged repairs of complex lesions or replacement of outgrown or degenerated prosthetic material. The vast majority of re-do operations proceed without incident; however, re-operation entails greater risk of inadvertent injury to the phrenic nerve and other heart and vascular structures, postoperative bleeding, and may require alternative cannulation sites. Recommendations to address these hazards are reviewed, as are areas of research that may impact future approaches to the patient who requires re-operation. Pericardial closure and pericardial substitutes, bovine and synthetic, are briefly discussed, as is the use of aprotinin for its hemostatic and anti-inflammatory effects.
