Insights
This study reports the first infant case of a large common iliac artery aneurysm caused by fibromuscular dysplasia (FMD). Surgical repair and medical management successfully controlled blood pressure.
Area of Science:
- Vascular Surgery
- Pediatric Cardiology
- Histopathology
Background:
- Fibromuscular dysplasia (FMD) is a rare non-atherosclerotic vascular disease.
- Iliac artery aneurysms are uncommon in infants.
- Renal artery stenosis is a known complication of FMD.
Observation:
- A seven-month-old infant presented with a large right common iliac artery aneurysm and bilateral renal artery stenoses.
- Surgical intervention involved interposing a Gore-Tex graft.
- Histological analysis confirmed medial fibromuscular dysplasia in the aneurysmal wall.
Findings:
- Successful surgical repair of the common iliac artery aneurysm.
- Postoperative blood pressure was normalized with medical therapy.
- This represents the first documented case of a common iliac artery aneurysm due to FMD in an infant.
Implications:
- Highlights the potential for FMD to cause significant vascular abnormalities in infants.
- Emphasizes the importance of considering FMD in pediatric patients with arterial aneurysms and stenoses.
- Suggests that surgical and medical management can be effective in pediatric cases.
Abstract:
A seven-month old female with a huge aneurysm of the right common iliac artery and multiple stenoses of her bilateral renal arteries is described. At surgery, a Gore-Tex graft was interposed between the proximal common iliac artery and the external iliac artery. A histological examination of the aneurysmal wall was compatible with medial fibromuscular dysplasia (FMD). After surgery, her blood pressure was controlled in the normal range on medical treatment. This case would be the first case of a huge common iliac artery aneurysm due to FMD in infants.
