The evolution of the pulmonary arterial sling syndrome, with particular reference to the need for reoperations because of untreated tracheal stenosis

Abstract

Our experience demonstrates that, in patients with a pulmonary arterial sling, any associated tracheal stenosis should be explored at the initial operation, since decompression of the trachea by reimplanting the anomalously located pulmonary artery fails to provide relief. The funnel trachea, if present, undergoes progressive stenosis, and will require surgical repair. The use of cardiopulmonary bypass permitted extensive mobilization of the tracheobronchial tree, and allowed us to perform a tension-free anastomotic reconstruction of the trachea.

“…9 Patients usually present with respiratory symptoms, including recurrent chest infection and other respiratory distress. 5,10,11 Three-dimensional reconstructions of CT scans and two-dimensional echocardiography are useful tools to establish pulmonary artery sling diagnoses. 12 Once pulmonary artery sling is diagnosed, a patient must undergo a surgical procedure.…”

Pulmonary artery sling: An overview

“…Untreated tracheal stenosis especially with complete rings may progress and require intervention, although mild cases may be managed without tracheal surgery. However this concept remains as controversial 33,62–65 …”
