BackgroundPulmonary artery sling (PAS) is rare, often with tracheal stenosis. And the postoperative mortality is high. For now, there is no consensus on the tracheoplasty for the patients with PAS and tracheal stenosis.MethodsStudies involving surgical repair of PAS and tracheal stenosis with and without tracheoplasty were identified by searching the PubMed, EMBASE, and the Cochrane Library databases until June 5, 2019. The assessed variables included ventilation time, early and late mortality, and symptom at follow-up. A random-effect/fixed-effect model was used to summarize the estimates of the mean difference (MD)/risk ratio (RR) with 95% confidence interval (CI).ResultsThis study will be submitted to a peer-reviewed journal for publication.ConclusionThis study will assess the safety and efficacy of tracheoplasty for patients with PAS and tracheal stenosis, and provide more evidence-based guidance in clinical practice.Prospero Registration NumberCRD42019139788.
