“…anomaly. There have been two reported circumstances including tracheal bronchus (3,4) PLPA is basically left unaltered in all reported cases because the vascular anomaly itself does not result in a cyanotic condition or respiratory distress. Anatomical repair of the associated cardiac and respiratory system defects is a key factor in the patient's prognosis.…”

“…Partial anomalous left pulmonary artery (PLPA) is an extremely rare type of aberrant pulmonary artery (1)(2)(3) and can be associated with tracheobronchial anomaly and congenital cardiac defect (2)(3)(4)(5). In contrast to the typical aberrant pulmonary artery, which always leads to a pulmonary sling, PLPA usually does not cause airway compression.…”

: Hereby, the case of an 8-month-old girl diagnosed with partial anomalous left pulmonary artery (PLPA) is presented. Echocardiography and computed tomography (CT) examination demonstrated that the anomalous artery originated from the right pulmonary artery supplying the left upper lobe. PLPA is sometimes associated with tracheobronchial anomaly and congenital cardiovascular defects. A relationship between PLPA and Kabuki syndrome has also been suggested. Echocardiography and CT angiography can be used as accurate tools for identifying an anomalous left pulmonary artery and adjacent abnormal anatomic structures.

“…Therefore, a great deal of researches have focused on the measurement and application of computed tomography (CT) to lung volume assessment (8,9). Moreover, there is evidence that CT can show the relationship between blood vessels, the trachea and its branches, and the position, range, and degree of tracheal stenosis (10,11). CT can also help evaluate and diagnose other cardiac malformations (12).…”

Background: Pulmonary artery sling (PAS) is associated with tracheal stenosis and left pulmonary artery (LPA) dysplasia in infants, both developmental abnormalities that may lead to pulmonary hypoplasia and lung volume changes. As such, we aimed to monitor the effects of tracheal stenosis and pulmonary vascular malformation on lung volumes in infants with PAS and their correlation with lung volumes in infants with PAS using dual-source computed tomography (DSCT).Methods: A case-control study was performed. From May 2009 to June 2017, we retrospectively enrolled patients with surgically confirmed PAS and compared them to matched normal controls (A healthy control group comprising age-and gender-matched patients with adequate imaging data was used for the comparisons.). All the patients underwent DSCT examinations. We measured and compared the diameters of the trachea, main bronchus, and main pulmonary artery (MPA) and its branches, and both lung volumes on the axial, and reconstructed CT images.Results: There were no statistical differences in the diameters of the MPA or right pulmonary artery (RPA) between patients (N=15) and controls (N=28). The diameter of the main bronchus, the bilateral trachea and the left pulmonary artery were all smaller in the PAS group than in the control group, and significant differences were evident in the left lung volume the right lung volume, and the right-to-left lung volume ratio between the 2 groups. Pearson's correlation and linear regression analyses between the diameters of the trachea and MPA, total lung volume, ipsilateral bronchial and pulmonary artery branches, and ipsilateral lung volume ranged from 0.71 to 0.87 and 0.57 to 0.77 for the control and PAS groups, respectively.Conclusions: Tracheal stenosis and LPA dysplasia in infants with PAS cause alterations in lung tissue morphology and physiological development, resulting in reduced bilateral lung volumes.

Multislice Computed Tomography Assessment of Tracheobronchial Patterns in Partial Anomalous Left Pulmonary Artery

Abstract: The PALPA can be associated with tracheobronchial anomalies and airway compression depending on its orientation to the airway. Noninvasive imaging modalities such as MSCT will be helpful for making further management decisions.
