Insights
Pediatric mycotic iliac aneurysms are rare. This case highlights successful management of a complex mycotic iliac aneurysm in a child using stent-graft deployment and subsequent surgical intervention.
Area of Science:
- Vascular Surgery
- Pediatric Cardiology
- Infectious Diseases
Background:
- Iliac aneurysms are uncommon in pediatric patients, with mycotic aneurysms being particularly rare.
- Revascularization in infected fields poses challenges due to patency concerns and growth potential in children.
Observation:
- A 12-year-old boy with a history of infective endocarditis presented with a right common iliac mycotic aneurysm.
- Initial treatment involved balloon-expandable stent-graft deployment, followed by recurrent abdominal pain due to appendiceal inflammation and an endoleak.
Findings:
- A second intervention included laparotomy, ligation of the right internal iliac artery, appendicectomy, and omental pedicle placement.
- Six-month follow-up showed a patent stent-graft and no residual collection, with the patient in good health.
Implications:
- This case demonstrates a successful multimodal approach to managing complex pediatric mycotic iliac aneurysms.
- Effective treatment strategies are crucial for improving outcomes in rare pediatric vascular conditions.
Abstract:
Iliac aneurysms are rare in children, especially mycotic aneurysms. Re-vascularization is challenging given the infected field and concern on patency due to their growth potential and a longer life-span. We report a complex case of a mycotic iliac aneurysm in a child. A 12-years-old boy with a previous history of infective endocarditis was referred to us for a right common iliac mycotic aneurysm after presenting with pain. A balloon-expandable stent-graft was deployed across the aneurysm during the acute presentation. He improved post-operatively, but developed abdominal pain four weeks later. A repeat computed tomography (CT) imaging showed a new inflammation of the appendix which was adhered to the calcified wall of the aneurysm and an endoleak from the internal iliac artery. A laparotomy was performed and the right internal iliac artery ligated along with an appendicectomy and omental pedicle. Postoperatively the patient was well and discharged home. Six-month surveillance revealed a healthy child and imaging showed a patent stent-graft and no residual collection.
