Abstract:
Mycotic pseudoaneurysim of the pulmonary artery that ruptures during necrotizing pneumonia is a rare entity that is often fatal. Traditionally it has been treated with open thoracotomy and resection of both the aneurysm and the lobe in which the aneurysm is located. In this report, we describe the radiological findings and transcatheter coil embolization of a mycotic pulmonary pseudoaneurysm in a 6-month-old female infant. We also describe the subsequent morphologic changes observed on follow-up computed tomography after 9 months of embolization.
Insights
Mycotic pulmonary artery pseudoaneurysms, often fatal, can be treated with transcatheter coil embolization. This minimally invasive approach shows promising results in infants, avoiding open surgery.
Area of Science:
- Interventional Radiology
- Pediatric Cardiology
- Pulmonary Medicine
Background:
- Mycotic pseudoaneurysms of the pulmonary artery are rare and frequently fatal, especially when rupturing during necrotizing pneumonia.
- Traditional treatment involves open thoracotomy and resection, carrying significant risks, particularly in infants.
Observation:
- This report details a case of a 6-month-old infant with a mycotic pulmonary artery pseudoaneurysm.
- Radiological findings were documented, highlighting the diagnostic challenges.
Findings:
- Transcatheter coil embolization was successfully performed to treat the mycotic pseudoaneurysm.
- Follow-up computed tomography at 9 months revealed significant morphologic changes post-embolization, indicating successful treatment and vessel remodeling.
Implications:
- Transcatheter coil embolization offers a less invasive alternative to surgery for mycotic pulmonary artery pseudoaneurysms in infants.
- This technique may improve outcomes and reduce morbidity associated with traditional surgical approaches.
