Summary
Umbilical artery catheters can lead to aortic aneurysms in children. Early recognition of mediastinal masses in septicemic infants is crucial for diagnosing these rare but life-threatening mycotic aneurysms.
Area of Science:
- Pediatric cardiology
- Vascular surgery
- Infectious diseases
Background:
- Umbilical artery catheters (UACs) are commonly used in neonates for monitoring and treatment.
- Complications associated with UACs, though infrequent, can be severe.
- Aortic aneurysms are rare in children, with mycotic aneurysms posing a significant threat.
Observation:
- Three pediatric cases are presented where aortic aneurysms were found adjacent to the tip of a UAC.
- Clinical presentations and radiographic findings suggestive of these aneurysms were documented.
- The proposed pathogenesis links UAC placement to the development of these vascular lesions.
Findings:
- The study describes the specific presentation of aortic aneurysms in relation to UAC placement.
- Radiographic evidence, including mediastinal mass, is highlighted as a key diagnostic clue.
- The pathogenesis suggests a potential mechanism for aneurysm formation secondary to catheterization and infection.
Implications:
- Early identification of mediastinal masses in septicemic children with UAC history is critical.
- Prompt diagnosis and treatment of mycotic aneurysms are essential for improving patient outcomes.
- This highlights the importance of vigilance for rare UAC-associated complications in pediatric care.
