Respiratory Symptoms due to Vascular Ring in Children

GM Zheng, XH Wu, lF Tang


Abstract

Aim: To highlight the clinical features, signs and diagnosis of vascular ring. Methods: A total of 33 patients (22 boys and 11 girls) diagnosed from January 2010 to July 2014 were enrolled. The types of vascular ring, basic demographic data, clinical symptoms, imaging and associated other malformations were analysed. Results: Among these patients, pulmonary artery sling was found in 17, right aortic arch in 9, double aortic arch in 5, and aberrant right subclavian artery in 3 (one with pulmonary artery sling). The median age (min-max) at onset and diagnosis were 1.8 (0.0-8.4) and 6.9 (0.1-149.0) months, respectively. Patients with pulmonary artery sling had higher incidence of stridor and dyspnea than patients with right aortic arch (P=0.028 and P=0.036, respectively). All patients combined with other anomalies, including airway anomalies in 31 (93.94%) and cardiovascular anomalies in 23 (69.70%). The diagnostic accuracy of computed tomography with contrast/angiography, magnetic resonance imaging and cardiac catheterisation angiography were high (up to 100%) and lower with X-ray and endoscopy. Conclusion: Vascular ring should be considered in infants and young children with recurrent or chronic respiratory complaints and other anomalies. Computed tomography with contrast/angiography or magnetic resonance imaging should be performed to confirm the diagnosis.
