Major mediastinal injury from crossbow bolt

We treated a 26-year-old male who sustained a self-inflicted injury to the mediastinum with a crossbow bolt. Injuries involved penetration of the sternum 1 cm below the sternomanubrial joint, right lung, pericardium, ascending aorta, right pulmonary artery, esophagus, and azygos vein. He was treated successfully with cardiopulmonary bypass and hypothermia. Exposure was achieved with a combination of a sternotomy and right thoracotomy.
