Abstract
OBJECTIVE: Spiral CT (SCT) angiography and three-dimensional (3D)
reconstruction methods represent noninvasive tools in diagnosis of vascular
rings and associated tracheobronchial anomalies in the pediatric age group.
MATERIALS AND METHODS: Three patients suspected on clinical and
conventional radiological grounds of having vascular and tracheobronchial
anomalies were examined using SCT. Three-dimensional images were
reconstructed using a surface rendering technique. RESULTS: In one case the
diagnosis of complete double aortic arch was confirmed by angiography. In the
other two patients the SCT and 3D reconstruction established the diagnosis of
pulmonary sling and right aortic arch associated with left aberrant subclavian
artery and angiography could be avoided. CONCLUSION: Spiral CT and
color-coded 3D reconstruction represent important additional tools and
perhaps alternatives to angiography or other noninvasive techniques used in
evaluation of vascular anomalies of the thoracic aorta and pulmonary arteries
in infants and children.
