Insights
Persistent fifth aortic arch (AA) is a rare congenital heart defect. This case highlights successful surgical repair in an infant, improving aortic obstruction and bronchial malacia.
Area of Science:
- Cardiology
- Pediatric Surgery
- Congenital Heart Disease
Background:
- Persistent fifth aortic arch (AA) is a rare congenital anomaly.
- It is frequently associated with aortic obstructive diseases.
- This condition can lead to complex cardiovascular and respiratory issues.
Abstract:
Persistent fifth aortic arch (AA) is a rare anomaly in congenital heart disease, which is often associated with aortic obstructive diseases. We report a 7-month-old infant diagnosed with persistent fifth AA with left ventricular dysfunction along with left bronchial malacia due to compression from their own heart. Surgical repair was performed, including AA reconstruction using the fifth AA as an in situ flap to enlarge the fourth AA with end-to-end anastomosis, and external stenting for the left bronchial malacia. Postoperative courses were uneventful. On computed tomography, a reconstructed AA without obstruction and an expanded left bronchus were seen.
