ABSTRACT

Left pulmonary artery sling (LPAS) is a rare form of vascular ring, in which the left pulmonary artery (LPA) originates from the right pulmonary artery (RPA), runs posterior to the trachea and leads to an airway compression. We present the case of a 30 day old girl with delayed growth, respiratory distress and desaturation. Large Atrial Septal Defect (ASD), patent ductus arteriosus (PDA) and LPA agenesia/hypoplasia were reported as initial echocardiography findings. The diagnosis of LPAS with tracheal stenosis was finally made by CT-scan.
The echocardiographic particularities of Left pulmonary artery sling (LPAS) may be known to avoid diagnostic errors. The cardiac scanner remains an excellent imaging tool for the confirmation and evaluation of the impairment on the tracheobronchial tree.
