[Severe tracheo-bronchial compression caused by a circumflex aorta. Apropos of 3 cases treated by aortic uncrossing]
Insights
This study highlights how a rare aortic arch anomaly can severely compress a child's airway. Surgical correction of the vascular arch is crucial for successful extubation and to rule out tracheomalacia.
Area of Science:
- Pediatric Cardiology
- Thoracic Surgery
- Congenital Heart Disease
Background:
- An encircling right aortic arch with a left-sided descending aorta is a rare congenital vascular anomaly.
- This condition can lead to significant compression of the tracheo-bronchial tree in infants and children.
Observation:
- Three pediatric cases presented with severe tracheo-bronchial compression due to this aortic arch abnormality.
- All affected children also had an associated ventricular septal defect.
Findings:
- The aorta itself was the primary structure causing airway compression.
- Successful extubation was achieved only after surgical correction ('uncrossing') of the abnormal vascular arch.
Implications:
- Accurate diagnosis and surgical intervention are vital for managing airway compromise in these patients.
- Tracheo-bronchial fibroscopy is essential to exclude residual compression before diagnosing tracheomalacia post-operatively.
Abstract:
The cases of three children with an encircling right aortic arch and left sided descending aorta illustrate the fact that this rare abnormality may cause severe compression of the tracheo-bronchial axis. A ventricular septal defect was associated to the abnormal vascular arch in all three cases. The compressive structure was the aorta and these children could only be extubated after surgical uncrossing . Before diagnosing tracheomalacia in a child operated for an abnormal vascular arch, residual compression must be excluded by tracheo-bronchial fibroscopy.
