This study presents a safer method for repeat sternotomies using a specific surgical saw. The improved technique successfully prevented cardiac or great vessel injuries in 75 patients undergoing repeat sternotomies.

Area of Science:

  • Cardiovascular Surgery
  • Surgical Techniques

Background:

  • Repeat sternotomies are challenging due to scar tissue and altered anatomy.
  • Previous midline sternotomies increase the risk of injury during re-entry.

Purpose of the Study:

  • To describe an improved method for repeat sternotomy.
  • To evaluate the safety and efficacy of a novel technique for opening the sternum after prior sternotomies.

Main Methods:

  • Utilized the Stryker(R) pneumatically-driven Sagittal Saw with a right-angled blade for sternal re-entry.
  • Performed approximately 75 repeat sternotomies over a two-year period.

Main Results:

  • The described method demonstrated a zero-incident rate of cardiac chamber or great vessel injury.

  • Successful sternal opening was achieved in all cases.

    • Conclusions:

    • The improved sternotomy technique using the specified saw is safe and effective for repeat procedures.
    • This method minimizes the risk of catastrophic injury in patients requiring re-operation.
