M. Tanabe et al., Doppler flow patterns through the ductus arteriosus in patients with congenital diaphragmatic hernia, EUR J PED S, 10(2), 2000, pp. 92-95
We investigated Doppler flow patterns through the ductus arteriosus (DA) of
13 newborn infants with congenital diaphragmatic hernia (CDH) using color
Doppler ultrasonography (CDUS). Patterns were classified into 3 types: left
-to-right (L-R), bidirectional (BD) and right-to-left (R-L) shunting. Among
the 13 patients examined, 3 showed L-R shunting, 5 BD shunting and 5 R-L s
hunting. Patients with L-R shunting showed significantly better levels of P
aO2 and AaDO(2) than those with other Doppler flow patterns. However, there
were no differences in clincial findings between patients with ED and R-L
shunting. All patients with L-R shunting survived after CDH repair without
pre-operative stabilization including Lipo-PGE, (LPE) administration. Four
of the 5 patients with ED shunting survived, but only one of the 5 patients
with R-L shunting survived after CDH repair following administration of LP
E. It was suggested that Doppler flow patterns through the DA may be useful
for predicting prognoses and selecting suitable treatment for CDH.
