Prognostic analysis of patients with pulmonary artery sling combined with tracheal stenosis without tracheal intervention / 中华实用儿科临床杂志

ABSTRACT

Objective To analyze the prognosis of patients with pulmonary artery sling (PAS) combined with tracheal stenosis(TS) without tracheal intervention,and to discuss the method for improving the effect of treatment.Methods The clinical data of 17 children with PAS/TS (moderate or severe) who received treatment at Beijing Bayi Children's Hospital Affiliated to General Hospital of Bejing Military Command from October 2011 to July 2015 were retrospectively analyzed,and the relationship between the effect and prognosis of re-implantation of the left pulmonary artery (LPA) without tracheal intervention was analyzed.Results Seventeen patients received re-implantation of the left pulmonary artery without tracheal intervention.Extubation was successfully performed in 12 of the 17 patients and they healed.The remaining 5 patients received tracheal intervention after the first operation but they all died.Of those 5 patients,3 received tracheal stent implantation (1 died from necrotizing enterocolitis,2 died from infection and multiple organ failure),and 2 received traheoplasty (both of them died from infection and tracheal fistula).Respiratory symptoms were reduced or resolved in all survivors.Diameter/length (％) in survivors without tracheal intervention was significantly higher than those who received tracheal intervention [(10.14 ± 1.58) ％ vs.(5.72 ± 1.17) ％,t =3.600,P ＜ 0.001].Patients with PAS undergoing LPA re-implantation achieved a good outcome if the diameter/length(％) of the trachea was up to (10.14 ± 1.58) ％.Patients with PAS undergoing LPA re-implantation achieved a bad outcome if the diameter/length(％) of the trachea was below to (5.72 ± 1.17) ％.Conclusions Most of patients with PAS/TS undergoing LPA re-implantation without tracheal intervention have a good outcome.It is feasible for them to avoid tracheal intervention.Diameter/length (％) may be a reliable indicator for determining tracheal intervention in surgical management of PAS.
