“…También se ha descrito una variante en que el pulmón derecho está completamente ventilado por este bronquio displásico. en ambos casos, la carina se encuentra en un nivel normal, frente a las vértebras T4 y T5, presentando una pseudocarina a nivel T6-T7 19 . el bronquio puente se puede asociar, entre otras alteraciones, a un cabestrillo de la arteria pulmonar izquierda (también conocido como sling de la arteria pulmonar), una anomalía vascular rara en que la arteria pulmonar izquierda se origina de la arteria pulmonar derecha, pasa por encima del bronquio derecho y entre la tráquea y Figura 8B.…”

“…The BB supplying the right middle and lower lobe originates at the level of the interspace between the sixth and seventh thoracic vertebrae. The right lung in patients with this subtype is frequently hypoplastic [4]. In both variants the angle of origin of the BB from the left main bronchus is increased compared with normal bifurcation giving the ''pseudocarina'' the configuration of an inverted T [4,[6][7][8].…”

Bridging bronchus (BB) is a rare, congenital bronchial anomaly that is frequently associated with congenital cardiac malformations, especially left pulmonary artery sling. It represents an anomalous bronchus to the right originating from the left main bronchus. Discrimination from other bronchial anomalies is important, since BB is frequently associated with bronchial stenoses due to abnormal cartilage rings.This case study describes the findings of bronchoscopy, bronchography and multidetector computed tomography (MDCT) in three patients. Bronchoscopy was helpful in the description of the severity and length of bronchial stenoses. However, it was not possible to establish a diagnosis of BB based on this method in two patients, since it is difficult or even impossible to differentiate the bifurcation from the pseudocarina. It was not possible to establish the correct diagnosis in all patients based on bronchography or MDCT. MDCT was able to depict the relationship of bronchial and vascular structures, which is particularly important in patients with pulmonary artery sling.Multidetector computed tomography is preferable to bronchography as it is less invasive and due to its short acquisition time it can be performed in children with severe respiratory disease. In the current authors' experience, detection of cartilage rings still requires flexible bronchoscopy.
