Sternal stabilization by interlocking wires: an alternative simple technique for high-risk patients.

BACKGROUND

Sternal dehiscence following midline sternotomy is associated with significant morbidity and mortality in high-risk patients.

METHODS

A novel simple technique of sternal stabilization after midline sternotomy by interlocking wires was introduced in high-risk patients with morbid obesity, diabetes, osteoporosis, chronic obstructive pulmonary disease, bilateral internal thoracic artery harvesting, or various combinations of the above.

RESULTS

A sternal stabilization by interlocking wires was performed in 25 consecutive high-risk patients. Stable sternum was achieved in all patients despite multiple risk factors.

CONCLUSION

We describe a simple technique of interlocking wires that provides excellent stabilization of the sternum after midline stenotomy in high-risk patients. This technique utilizes the benefit of figure-eight wires, provides the continuity of the weave and effectively prevents cutting of the wires through the sternum without compromising its blood supply.
