[Surgery for a Missile Embolus in the Right Ventricle].

Ballistic embolism represents an unusual complication of vascular by a flying object injury. Because embolus is remote from injury site, the occurrence of missile embolus may be overlooked and lead to delay in diagnosis of significant ischemia or embolism. We herein report a successful surgical removal of a rare missile embolus from the upper arm in the right ventricle. A 44-year-old man visited our hospital because of pulsatile bleeding from the left upper arm due to injury by a flying metal fragment of a hammerhead. Chest roentgenogram and computed tomography (CT) scan 9 days after the injury demonstrated a missile embolus in the right ventricle, which was thought to be ballistic embolism of the metal fragment. We underwent surgical removal of the retained object under cardiopulmonary bypass uneventfully, and discharged home ten days later.
