resternotomy
Surgical reopening of a previously divided sternum in patients with prior cardiac surgery.
Full Definition
The surgical procedure of re-dividing the sternum in patients who have undergone previous cardiac surgery, typically involving the use of an oscillating saw to cut through scar tissue and bone. This procedure carries increased risks including bleeding from adhesed structures, injury to mediastinal organs, and hemodynamic instability. Anesthesiologists must be prepared for potential cardiovascular collapse and have immediate access to cardiopulmonary bypass. The procedure requires careful coordination between surgical and anesthesia teams.
Usage
Usage note: Preferred over 'redo sternotomy' in formal documentation; always indicates previous cardiac surgery.
