Insights
A pediatric case of infantile Marfan syndrome presented with early aortic aneurysm rupture. Surgical repair involved a composite graft, followed by homograft replacement due to stenosis, with excellent long-term outcomes.
Area of Science:
- Cardiology
- Pediatric Surgery
- Genetics
Background:
- Infantile Marfan syndrome is a rare genetic disorder affecting connective tissue.
- Aortic aneurysm rupture in young children is a life-threatening emergency.
- Early diagnosis and intervention are crucial for managing Marfan syndrome complications.
Observation:
- A 3-year-old boy diagnosed with infantile Marfan syndrome experienced premature rupture of his aortic aneurysm.
- Emergency surgery was performed, utilizing a composite graft constructed from a St. Jude prosthesis and a vascular conduit.
- The patient developed several postoperative complications, including pneumothoraces, phrenic nerve paralysis, seizures, and supraventricular tachycardia.
Findings:
- The initial composite graft required replacement with an aortic homograft due to severe stenosis four months after the primary surgery.
- Despite initial complications and graft revision, the patient demonstrated an excellent clinical condition 12 months postoperatively.
Implications:
- This case highlights the critical need for vigilant cardiovascular monitoring in children with Marfan syndrome.
- Composite grafts can be a viable, albeit temporary, solution for aortic emergencies in pediatric patients.
- Aortic homografts may be a suitable option for long-term management of aortic stenosis in this population, offering favorable outcomes.
Abstract:
A 3-year-old boy with early rupture of an aortic aneurysm due to infantile Marfan's syndrome is presented. In an emergency operation we prepared a composite graft using a 17-mm St. Jude prosthesis with an 18-mm vascular conduit. The postoperative period was complicated by pneumothoraces, transient bilateral phrenic nerve paralysis, cerebral convulsion, and supraventricular tachycardia. Four months postop the composite graft was replaced with an aortic homograft due to severe stenosis. His condition after 12 months is excellent.
