Neonatal mortality in dogs: Prognostic value of Doppler ductus

Abstract
Aim:
To define the prognostic value of Doppler ultrasonographic
morphology of ductus venosus (DV) waveform on canine neonatal
mortality.
Materials and Methods:
Fifty-four healthy pregnant bitches underwent fetal
ultrasonographic assessment. The DV waveforms were classified as
diphasic (dDVw) or triphasic (tDVw) and compared with neonatal
mortality.
Results:
Ninety-three fetuses were evaluated. Twenty fetuses belonged to
litters with neonatal mortality, in which tDVw was observed.
Seven fetuses belonged to litters without neonatal mortality, in
which tDVw was observed. Fifty-eight fetuses belonged to litters
without neonatal mortality, in which only dDVw was observed.
Eight fetuses belonged to litters with neonatal mortality, in
which only dDVw was observed. The correlation between tDVw and
neonatal mortality was statistically significant (odds ratio
[OR], 20.7; p<0.0001). Considering only pregnancies with one or
two fetuses with the same DV waveform: Two fetuses with tDVw
belonged to litters with neonatal mortality; 1 foetus with tDVw
belonged to litter without neonatal mortality and 26 fetuses
showed dDVw without neonatal mortality. The correlation between
tDVw and neonatal mortality even in litters up to two pups was
statistically significant (OR, 88.3; p=0.01).
Conclusion:
Echo-Doppler assessment of DV is feasible in canine fetuses, and
the presence tDVw seems to be related to neonatal mortality.
Keywords:
