Unexpected migration of a sternal pin: A word of caution.

ABSTRACT

BACKGROUND: Sternal pins are adjuncts used to enhance sternal stability after sternotomy, but only a few complications associated with them have been previously reported. MATERIAL, METHODS AND RESULTS: A 42-year-old woman underwent pulmonary valve replacement through re-sternotomy for pulmonary valve regurgitation after repaired tetralogy of Fallot. Because of severe sternal deformity, the sternum was refixed using a sternal pin in addition to sternal wires. However, postoperative computed tomography unexpectedly revealed migration of the sternal pin towards the right coronary artery, necessitating emergency surgical removal of the pin. DISCUSSION: Sternal pins may not adequately fit the deformed sternum, resulting in sternal pin-induced sternal injury. CONCLUSION: Sternal pins are considered useful for sternal stabilization after sternotomy, we should take special care in applying sternal pins to patients presented severe sternal deformity.
