Pulmonary fiber embolism and granuloma

Area of Science:

• Medical Devices
• Pediatric Cardiology
• Pathology

Background:

• Cardiac catheterization is a common procedure in pediatric cardiology.
• The use of medical devices carries inherent risks.
• Previous complications associated with catheter materials have been documented.

Observation:

• Three infants developed pulmonary fiber embolism and granuloma post-cardiac catheterization.
• These serious complications were linked to the specific type of catheter used.
• The catheters were identified as nondisposable woven synthetic fiber types.

Findings:

• The fibrous lining of the synthetic fiber catheters can degrade and fragment.
• Dislodged catheter fragments can travel through the vasculature during angiography.
• These fragments act as emboli, leading to the formation of granulomas in the pulmonary vasculature.

Implications:

• This highlights a critical safety concern with specific woven synthetic fiber catheters.
• Recommendations for catheter material selection and inspection in pediatric procedures are warranted.
• Further research into alternative, safer catheter materials is essential to prevent similar adverse events.
