Double right tracheal bronchus. A case report in an infant
Insights
A rare double right tracheal bronchus was found in an infant with a paratracheal opacity and persistent cough. This congenital anomaly affected the entire right upper lobe, leading to atelectasis and abnormal blood supply.
Area of Science:
- Pediatric Surgery
- Thoracic Anatomy
- Congenital Malformations
Background:
- Tracheal bronchi are uncommon airway anomalies.
- A double right tracheal bronchus is exceptionally rare.
- Congenital lung abnormalities can present with respiratory symptoms.
Observation:
- A 12-month-old infant presented with a right paratracheal opacity, persistent cough, and ventricular septal defect.
- Tomography and tracheobronchography revealed a unique double right tracheal bronchus supplying the entire right upper lobe.
- Other upper lobe bronchial branches were absent.
Findings:
- The infant had a double right tracheal bronchus, a rare congenital anomaly.
- The right upper lobe exhibited atelectasis.
- Abnormal vascular supply to the right upper lobe was noted.
Implications:
- This case highlights the importance of recognizing rare congenital airway variations.
- Early diagnosis and surgical intervention are crucial for managing associated respiratory complications.
- Understanding such anomalies aids in surgical planning and patient outcomes.
Abstract:
An apparently unique case of double right tracheal bronchus supplying the whole right upper lobe is described in a 12-month-old infant presenting with a right paratracheal opacity, persisting cough, and ventricular septal defect. The two tracheal bronchi, initially discovered on tomography, were confirmed by tracheobronchography, which demonstrated also the absence of other upper lobe branches. At surgery, the upper lobe was atelectatic, and its blood supply was abnormal.
