Abstract：Objective To review the clinical significance of multi-slice spiral computed tomography (MSCT) in diagnosis of pulmonary artery sling with tracheal malformation. Methods The child patients with pulmonary artery sling with tracheal malformation (n=8) were chosen from Dec. 2009 to Jun. 2015, and the characteristics of MSCT were retrospectively analyzed. Results The diagnosis of pulmonary artery sling with tracheal malformation was definite in 8 patients before MSCT. MSCT showed that the left pulmonary artery originated from the right pulmonary artery, ran between trachea and esophagus and entered into hilus of lung. All 8 patients had tracheal stenosis in varying degrees, and 5 had local or short segment tracheal stenosis, 3 had long segment tracheal stenosis, 1 had tracheal bronchus and 1 had bridging bronchus. According to Wells classification, 4 cases had type 1A (normal bronchial branching pattern), 1 case had type lB (tracheal bronchus spread to right upper lobe), 2 cases had type 2A (typical bronchial bridge), and 1 case had type 2B (bronchial absence or blind-ending in right upper lobe with right lung dysplasia). Conclusion MSCT can not only display clearly anatomical morphology of pulmonary artery sling, but also determine the degree of tracheal compression and stenosis range. It is helpful for definitely diagnosing pulmonary artery sling and selecting proper therapies.
