Double vascular ring: a case report of double aortic arch and concurrent pulmonary artery sling.


ABSTRACT: BACKGROUND:Double aortic arch (DAA) and pulmonary artery sling (PAS) are vascular ring formations that present in neonates and infants with symptoms of respiratory stenosis. CASE SUMMARY:The patient was a girl with suspected ventricular septal defect (VSD), right aortic arch (AA), left patent ductus arteriosus, and bilateral superior vena cava (SVC) on foetal echography in the first day of life. The girl was delivered at 40?weeks and 4?days of gestation. Ventricular septal defect, DAA, coarctation of the left AA, and bilateral SVC were diagnosed. Contrast-enhanced computed tomography at Day 16 revealed PAS with concurrent anomalous tracheal branching in addition to DAA. The right A2 segmental artery, which supplies the right upper pulmonary artery, showed abnormal branching from the left pulmonary artery (LPA). At 3?months of age, VSD patching, left AA resection distal to the root of the left subclavian artery, arterial ligament dissection, and LPA replacement were performed. DISCUSSION:Pulmonary artery sling coexists with anomalous branching of the trachea and abnormal branching of the right pulmonary artery (RPA). Our patient had an extremely rare case of DAA concurrent with PAS and presented with anomalous tracheal and RPA branching. We were concerned that increased pulmonary blood flow caused by the VSD would exacerbate tracheal displacement. Radical surgery at 3?months of age resulted in good postoperative progress.
