“…The developmental anomalies of the bronchial tree were presented mostly as case reports in literature. In these reports there is usually an accompanying anomaly (Conacher, 2000;Elmaci et al, 2001;Bentala et al, 2002;Chau et al, 2003;Aoun et al, 2004;Heyer et al, 2004;Delpizzo et al, 2006;Ming et al, 2008;Leo et al, 2009;Grosu et al, 2012). In this present study, the developmental anomalies of the bronchial tree were detected in MDCT images that have no reported pathology.…”

SUMMARY:Anomalies of the bronchial tree may cause recurrent acute pulmonary infection and persistent obstruction symptoms. The developmental anomalies of the bronchial tree were presented mostly as case reports with an accompanying anomaly. However in this study, these anomalies were detected in multidetector computerized tomography (MDCT) images which have no reported pathology. Thoracic MDCT images of 400 patients (0-74 years old, 224 male and 176 female) were evaluated. Four tracheal bronchus (1%) were detected. Three of them were displaced type, one of them was pig bronchus. And two accessory cardiac bronchus (0,5%) originated from medial wall of the intermediate bronchus were detected. According to our findings, incidence of tracheal bronchus and accessory cardiac bronchus seems to be higher in Turkish population.

“…From an embryological standpoint, TRB develops between the 3rd and 7th week of gestation from an anomalous tracheal sprout which does not undergo regression or through implantation of bronchial mesenchyma within the trachea . It is usually associated with a wide variety of congenital anomalies or syndromes . As far as we know, this series is the most extensively described to date since most of the published data on TRB corresponds to case reports or small series of patients .…”

Tracheal bronchus (TRB) has been generally considered an anatomical variant of the tracheobronchial tree without a precise pathological effect. Its prevalence is estimated to be between 0.2% to 3% of all children undergoing bronchoscopy and scientific information has been limited to case reports or small case series. Our working hypothesis was that TRB could trigger by itself recurrent or persistent respiratory symptoms. The objective of this retrospective and multicentre study of children with a diagnosis of TRB, coming from the main paediatric pulmonology units of Spain, was to determine the anatomical and clinical characteristics, including comorbidities, of TRB in childhood and their impact in the patients' clinical outcomes. One hundred thirty‐three patients from 13 institutions were included in the study. Mean diagnostic age was 3.4 years and flexible bronchoscopy was the initial diagnostic method in 85% of cases. All TRB were located on the right wall of the trachea: 76% in the lower third and 24% in the carina. The most common clinical manifestations were obstructive bronchitis (53.3%) and recurrent pneumonia (46.6%), usually affecting the right upper lobe. Regarding associated anomalies, 33% had tracheomalacia, 32% congenital cardiovascular malformations, 28% gastroesophageal reflux, 22.5% congenital tracheal stenosis, and 8.3% Down syndrome. This series appears to be the most extensive published to date addressing this topic and, according to our data, TRB does not appear to be a mere incidental finding but is more likely linked to a wide range of congenital anomalies and contributes by itself to the recurrent respiratory symptomatology that these children exhibit.

“…The etiologic mechanisms for CLO are unusual flaccidity of the bronchial wall; abnormal or malformed bronchial cartilage; poorly developed cartilaginous rings (infantile bronchus); pulmonary artery sling; pulmonary rotation anomaly; bronchogenic cyst duplication of esophagus; mediastinal mass; polyalveolar lobe; bronchial polyp; redundant bronchial mucosal folds, septae, and webs; or compression of the bronchus by an abnormal vessel, collateral, or by dilated pulmonary arteries or an enlarged left atrium [11]. The characteristic finding is a progressive pulmonary hyperinflation of certain segments or one or more lobes, which is the result of a one-way valve ("ball-valve") mechanism of the abnormal airway causing air trapping.…”

“…If asymptomatic or if the symptoms are mild, the management is conservative. If the patient has clinical progression or is clinically severe, the treatment recommended is a lobectomy [11].…”

The incidence of congenital lobar overinflation (CLO) is reported at 1 in 20,000–30,000 live births and represents 10% of all congenital lung malformations. The occurrence of concomitant congenital heart disease (CHD) and CLO ranges from 12% to 20%. There are diverging views in the management as to whether early lobectomy or repair of the cardiac defect, with the assumption that respiratory symptomatology would gradually resolve, or a combined lung and cardiac repair would be the ideal first step in the management. In concomitant CLO and CHD, the surgical decision has to be individualized. Prior to surgical intervention a thorough evaluation may be needed with contrast computed tomography (CT) or magnetic resonance imaging (MRI), bronchoscopy, and if needed cardiac catheterization. CLO improves with management of many left to right shunts and in those with anomalous vessels, but early lobectomy or combined approach may be considered in those symptomatic patients with more complex CHD.
