Key result
Slide tracheoplasty and LPA reimplantation yield excellent long-term outcomes for pulmonary artery sling.
Why the study?
Pulmonary artery sling is a rare and challenging congenital vascular tracheobronchial compression syndrome frequently associated with tracheal stenosis and critical airway obstruction, requiring rapid diagnosis and surgical planning.
Rapid diagnosis and surgical management via slide tracheoplasty and left pulmonary artery reimplantation are essential for relieving critical airway obstruction and achieving excellent long-term outcomes in patients with pulmonary artery sling.

Supports combined slide tracheoplasty and reimplantation for pulmonary artery sling; leaves open need for prospective validation.
Pulmonary artery sling is a rare childhood vascular tracheobronchial compression syndrome that is frequently associated with tracheal stenosis.Consequently, neonates or infants may present with critical airway obstruction if there is long segment airway narrowing and complete rings.Rapid diagnosis of this cardiac vascular malformation and evaluation of the extent and severity of airway involvement is essential to plan surgery, typically a slide tracheoplasty to relieve critical airway obstruction.Long term outcome can be excellent following surgical repair of the stenosed airway and reimplantation of the left pulmonary artery.In this review we focus on the embryology, diagnostic workup, airway investigations and management for this rare but challenging congenital condition.

Choi et al. (2026) conducted a review in Pulmonary artery sling and associated tracheal stenosis. Slide tracheoplasty and reimplantation of the left pulmonary artery was evaluated. Surgical repair via slide tracheoplasty and left pulmonary artery reimplantation can yield excellent long-term outcomes for pulmonary artery sling with tracheal stenosis.
