Summary
This study highlights a rare cause of pediatric hemoptysis: anomalous systemic arteries supplying lung segments. Embolization of these arteries effectively stopped bleeding in children, offering a new treatment avenue.
Area of Science:
- Pediatric Pulmonology
- Vascular Malformations
- Interventional Radiology
Background:
- Hemoptysis in children is rare and often linked to systemic or pulmonary conditions.
- While anomalous arterial supply causing hemoptysis is documented in adults, it's exceptionally rare in pediatric cases.
Observation:
- Five pediatric patients, including one with bronchopulmonary dysplasia, presented with acute, severe hemoptysis.
- Standard investigations failed to reveal the cause of bleeding.
- Cardiac catheterization identified dilated anomalous systemic arteries supplying lung segments or arteriovenous malformations.
Findings:
- Anomalous systemic arterial supply was confirmed as the cause of hemoptysis in all cases.
- Embolization successfully occluded the anomalous arteries in all five patients.
- All patients experienced cessation of further hemoptysis post-embolization.
Implications:
- This case series suggests anomalous systemic arterial supply should be considered in pediatric hemoptysis when other causes are ruled out.
- Vascular embolization is an effective treatment for this rare condition in children.
- Further research into pediatric vascular anomalies causing hemoptysis is warranted.
