CTICasesPenetrating Cardiac Injury from a Nail Gun
Imaging findings
Lateral chest radiograph demonstrates a long metallic nail directly traversing the anterior chest wall and piercing the right ventricle of the heart.
Key takeaways
Penetrating cardiac injuries from construction tools like nail guns are highly lethal but potentially survivable if the nail remains in place, acting as a temporary seal to limit active exsanguination. Rapid transport, avoiding premature removal of the foreign body outside the operating room, and immediate median sternotomy are crucial for successful repair.
