[Radiological patterns of truncus arteriosus on X-ray plain film (author's transl)].
Fifteen cases of truncus arteriosus have been studied on frontal and lateral views of thoracic X-ray plain film in infants and children. In infants (12 radiological records), the left middle segment is concave or straight, mainly at the lower part and this pattern is typical if associated with an active pulmonary hypervasculature. Cases without marked pulmonary hypervasculature are very difficult to diagnose. On 7 lateral X-ray films we noted three patterns of empty retrosternal space which were visible at birth. In children from 2 to 6 years, a pattern of cardiomegaly with right aortic arch and pulmonary hypervasculature is very typical. In children older than 6 years, we noted a typical Eisenmenger syndrome. The pattern of empty retrosternal space was marked. In our experience, association of right aortic arch with pulmonary hypervasculature is very typical.
