Abstract:
Objective:To summarize the morphological characteristics and clinical experience of pulmonary artery sling(PAS) combined with anomalous bronchial branching, and provide new considerations for surgically treating PAS.Methods:A retrospective review of surgical experience of all patients with anomalous bronchial branching from January 2012 to December 2018 at Shanghai Children's Medical Center was conducted. There are 4 types according to the morphology of anomalous bronchial branching: tracheal bronchus, bronchial trifurcation, bridging bronchus, tracheal bronchus combined with bronchial trifurcation. The proportion of patients with anomalous bronchial branching combined with PAS was counted. The rate of tracheoplasty for four types was determined. We measured the interbronchial and subcarinal/subpseudocarinal angles before and after tracheoplasty.Results:140 patients were included in our study. The tracheal diameter of 11(21%, 11/53) patients with tracheal bronchus and 4(9%, 4/44) patients with bronchial trifurcation was normal. Among these patients, 125 patients had congenital tracheal stenosis(CTS). 115 patients underwent tracheoplasty. The rate of tracheoplasty of bridging bronchus was higher than tracheal bronchus(100% vs. 60%, P=0.000). One-stage surgery was performed in 76(61%) patients who had PAS. The interbronchial and subcarinal/subpseudocarinal angles were significantly reduced postoperatively( P=0.000). Conclusion:It is difficult to explain merely with vascular compression in patients with PAS with CTS and anomalous bronchial branching. One-stage slide tracheoplasty is currently the optimal option.
