Intracardiac malpositioning of a sternoclavicular fixation wire.

: A case of intracardiac malpositioning of a sternoclavicular Kirschner pin is reported. After an uneventful closed wire-fixation of sternoclavicular subluxation and a normal postanesthetic recovery, a 17-year-old male patient developed opacification of the right hemithorax and signs of internal bleeding. The lateral chest roentgenogram showed one fixation wire protruding deeply into the anterior mediastinum. Sternotomy showed a large pericardial tear communicating with the right pleural cavity and a puncture hole of the right auricle that had caused a blood loss of 3 L into the pleural space. Although the surgical repair was uneventful, the patient eventually died as a sequelae to prolonged cerebral hypoxemia.
