Insights
A child treated for mastoiditis developed multiple pulmonary artery pseudoaneurysms. Endovascular embolization successfully treated these life-threatening vascular abnormalities, avoiding surgery.
Area of Science:
- Vascular Surgery
- Pediatric Cardiology
- Interventional Radiology
Background:
- Mastoiditis, an infection of the mastoid bone, can rarely lead to serious complications.
- Pulmonary artery pseudoaneurysms are rare but potentially fatal vascular abnormalities.
Observation:
- A 5-year-old boy developed multiple, bilateral pulmonary artery pseudoaneurysms post-mastoiditis surgery.
- The pseudoaneurysms were too large and numerous for surgical intervention.
Findings:
- Successful endovascular coil and wire embolization was performed in staged procedures.
- This minimally invasive approach effectively treated the complex vascular condition.
Implications:
- Endovascular embolization offers a viable alternative for managing large, multiple pulmonary artery pseudoaneurysms in pediatric patients.
- Highlights the importance of vigilance for vascular complications after infections and surgical procedures.
Abstract:
The authors report a case of a 5-year-old boy who initially presented with mastoiditis, underwent successful surgical treatment, and during the immediate postoperative period developed multiple, bilateral pulmonary artery pseudoaneurysms. The large size and multiplicity of the pseudoaneurysms precluded the patient from undergoing thoracic surgery. Successful endovascular coil and wire embolization was performed in a staged set of procedures with use of more than 30 m of wire and coils.
