Abstract:
Three cases of aortic aneurysm adjacent to the tip of the umbilical artery catheter are described. The clinical presentation, radiographic findings, and proposed pathogenesis are discussed. Mycotic aneurysms in childhood are infrequent but serious threats to life, requiring early recognition and prompt therapy. The appearance of a progressively enlarging middle or posterior mediastinal mass in a child with a history of septicemia should suggest a mycotic aneurysm.
Insights
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.
