In pulmonary arterial sling (PAS), the left pulmonary artery (LPA) arises from the right pulmonary artery (RPA) and goes leftward between the trachea and the esophagus. This produces a sling around the distal trachea and the proximal bronchi. The LPA thus compresses the superior part of the right bronchus and the distal part of the trachea. Most patients with PAS have clinical symptoms related to tracheal or tracheobronchial compression. When tracheal hypoplasia coexists (ring-sling complex1Go), acute episodes of dyspnea and cyanosis are common and may cause major respiratory distress and death. Although the effect of PAS on lung ventilation is well known, the effect of the surgical correction of PAS on left lung perfusion has never been evaluated.

Clinical Summary

A 5-year-old boy with a history of recurrent pulmonary infections was referred to the pediatric pneumology department.

Preoperative examination
On examination, the patient was an alert and vigorous child weighing 18 kg. Results of clinical examination at . . . [Full Text of this Article]
