ultrasound diagnosis of fatal anomalies

DUODENAL ATRESIA
Fig. 6.2 Duodenal atresia. Across-section of the
fetus at the upper abdominal level at 27 weeks,
showing two cystic lesions (“double bubble”) following
duodenal atresia in a fetus with trisomy 21.
Fig. 6.3 Duodenal atresia. Same findings as above,
in longitudinal section.
Prognosis: This depends on coexisting malformations
and the maturity of the infant (premature
labor due to hydramnios). Mortality can be
as high as 36%. Surgical repair of isolated
duodenal atresia is successful in almost all cases,
with an overall survival rate of 95%.
