Interposition of hydroxyapatite ceramic stents alternative to delayed sternal closure.
Ascending and hemiarch replacement surgery for an acute Stanford type A dissection in association with a previous type B dissecting aneurysm was performed on a 58-year-old female patient. However, sternal closure could not be performed after surgery due to hemodynamic deterioration. Even four weeks after the operation, sternal closure was impossible due to advanced adhesion around the mediastinum caused by mediastinitis. Therefore, hydroxyapatite ceramic spacers, which have osteogenesis and ossification characteristics, were interposed between the split sternum as stents to avoid further surgery.
