A pulmonary artery sling is a very rare congenital abnormality in which the left pulmonary artery rises from the posterior surface of the right pulmonary artery and then passes between the trachea and the esophagus, causing tracheal compression. It is associated with tracheo-bronchial abnormalities (50%) and cardiovascular abnormalities (30%). It may produce respiratory symptoms through the airway compression of the abnormal left pulmonary artery and congenital abnormalities associated with it. Because most (90%) pulmonary artery sling patients present symptoms during infancy, their condition is often diagnosed in the first year of life. However, a pulmonary artery sling is occasionally found in adults. It is usually asymptomatic and found incidentally. This is a very rare case of an asymptomatic pulmonary artery sling in an adult. A 38-year-old man presented symptoms of mild exertional dyspnea. His spiral computed tomography showed a pulmonary artery sling. He was discharged without specific treatment because his symptoms improved without specific treatment and might not have been associated with a pulmonary artery sling. We report an adult case of an asymptomatic pulmonary artery sling diagnosed via spiral computed tomography, accompanied by a literature review.

Pulmonary artery sling is a rare congenital vascular anomaly in which the left pulmonary artery arises aberrantly from the proximal part of the right pulmonary artery and encircles the right main bronchus and distal trachea before entering the hilum of the left lung. This causes compression of the trachea and right main bronchus, and most infants with this anomaly have severe respiratory distress within the first year of life. Associated anomalies are common, and particularly, tracheobronchial anomalies occur in 40% of the patients. Major cardiovascular anomalies including ventricular septal defect, atrial septal defect, patent ductus arteriosus, tetralogy of Fallot, common ventricle, and coarctation of the aorta, occur in about half of the affected infants. We have experienced an 11-month-old male infant with respiratory distress, wheezing, and cyanosis. He was diagnosed as pulmonary artery sling associated with left bronchial hypoplasia by echocardiography, angiography, and chest CT scan. Other associated anomalies were left kidney agenesis, right megaureter and right kidney hypertrophy, diagnosed by abdominal sonography and IVP. We report this case with a brief review of literature.

Clinical Course of Vascular Rings and Risk Factors Associated With Mortality

Background and Objectives: Vascular rings refer to anomalies of the great arteries that cause respiratory or feeding problems. The purpose of this study was to analyze a series of patients with vascular rings and evaluate associated risk factors for mortality. Subjects and Methods: A retrospective review of all patients identified with vascular rings between 1997 and 2010 in the Seoul National University Children’s Hospital. Results: Thirty-five patients were diagnosed with vascular rings (median age at diagnosis, 7 months). The vascular rings of 32 patients were confirmed by cardiac computed tomography or magnetic resonance imaging. The types of vascular rings were: a double aortic arch in ten patients, a right aortic arch with persistent left ligamentum arteriosum in seven, an aberrant subclavian artery in seven, a pulmonary sling in eight, and others types in three patients. Eleven patients were asymptomatic. Gastrointestinal and respiratory symptoms were seen in ten and sixteen patients, respectively. Associated cardiovascular anomalies were present in fifteen patients. Twenty patients with definite symptoms underwent surgical treatment. The median interval between diagnosis and operation was 6 days. Four patients eventually died; three deaths were associated with complex heart diseases, and one had pulmonary artery sling with severe tracheal stenosis. Only the presence of a complex heart disease significantly influenced mortality (p=0.002). Conclusion: Vascular rings include several types of anomalies, each with a different prognosis and symptoms. The presence of a complex heart disease was significantly associated with mortality. Early diagnosis and timely surgery in symptomatic patients are essential.
