resternotomy
Pronunciation: ree-ster-NOT-uh-mee
Reopening of a previously divided sternum for subsequent cardiac surgery.
Full Definition
Resternotomy is the surgical reopening of the sternum in patients who have previously undergone cardiac surgery requiring median sternotomy. This procedure carries increased risks due to adhesions between the heart and chest wall, potential injury to cardiac structures, and bleeding complications. Careful dissection techniques and sometimes the use of oscillating saws are required to safely enter the mediastinum. Documentation must include the indication for reoperation and any complications encountered during sternal re-entry.
Usage
Usage note: Distinguished from primary sternotomy. Often described as 'redo' sternotomy in clinical documentation.
