Bullet embolus to the right pulmonary artery after abdominal gunshot wound with "piggyback bullet".

ABSTRACT

This report describes a 17-year-old man with piggyback bullets to the abdomen followed by bullet embolization to the right pulmonary artery. The first bullet was removed from the abdomen while the second missile in the lung was left intact. We believe this is the first case in Thailand of a bullet embolus resulting from piggyback bullets.
