Pulmonary vein to systemic artery missile embolus

Area of Science:

• Cardiovascular Surgery
• Trauma Management
• Vascular Embolism

Background:

• Pulmonary vein to artery missile embolus is an exceedingly rare clinical occurrence.
• Literature review reveals only one prior reported case globally.
• This case represents a unique instance of patient survival.

Observation:

• A patient presented with a missile embolus originating in the pulmonary vein and migrating to an artery.
• The primary wound management was critical for patient outcomes.
• Foreign body extraction was deemed secondary to initial wound stabilization.

Findings:

• Prompt and appropriate primary wound care is the cornerstone of managing missile emboli.
• Surgical intervention for foreign body removal is indicated only when distal perfusion is compromised.
• Catheter-based embolectomy is contraindicated due to the risk of intimal damage.

Implications:

• Direct arteriotomy is the preferred method for surgical extraction of arterial foreign bodies.
• This case highlights the importance of a systematic approach to rare vascular injuries.
• Effective management strategies can improve survival rates in complex embolic events.
