The purpose of this study was to explore the useful
imaging findings of electron beam computed tomography
(EBCT) for diagnosing pulmonary venous obstruction
(PVO) in children with congenital heart disease.
From July 1995 to March 1998, 17 children (9 girls and
8 boys, aged 7 days to 14 years and 9 months [median
3 months]) with the diagnosis of PVO were enrolled in
this study. All images were obtained by EBCT at the
end-diastolic phase of the cardiac cycle after administration
of intravenous iodinated contrast medium. The
findings of 25 EBCT studies were retrospectively analyzed
by 2 radiologists and were correlated with echocardiography,
angiocardiography, and surgical findings.
Main findings on EBCT for PVO were (1) structural
narrowing, (2) thickened interlobular septa, (3) peribronchovascular
cuffing, and (4) ground-glass opacity
of the alveoli. Structural narrowing along the course of
the pulmonary venous drainage was the most important
finding in all examinations (25 of 25). Lung parenchymal
changes secondary to PVO included thickened interlobular
septa (17 of 25), peribronchovascular cuffing
(15 of 25), and ground-glass opacity of the alveoli (8 of
25). Thus, the combination of these findings provides
very useful data for the definitive diagnosis of PVO.
Characteristic electron beam computed tomographic
findings can validate suspected PVO noninvasively.
