Background
- Also known as "bullet embolism"
- Occurs when a bullet or bullet fragment enters the bloodstream.
- Can be arterial (80%) or venous[1]
- Usually a small-caliber, low velocity projectile.[1]
- For this reason, incidence higher in non-military setting due to predominance of lower velocity projectiles
- Incidence = 1.1% in recent combat operations[2]
Clinical Features
- Number of entry wounds do not match exit wounds
- Location of bullet not consistent with predicted trajectory
- Bullet within intravascular or cavity without evidence of adjacent direct tissue injury
- Fluoroscopy showing foreign body move within vascular cavity
- CXR showing blurred foreign body within cardiac silhouette
Differential Diagnosis
Diagnosis
- Need to maintain high index of suspicion, obtain full body radiography when indicated[1]
Management
- Controversial - not all need to be removed.
