AbstractExtreme Doppler abnormalities of the umbilical artery such as absent or reversed end diastolic velocity are associated with adverse perinatal outcomes. We present a case of a triphasic umbilical artery waveform identified at 24 weeks. The fetus was severely growth restricted with an estimated fetal weight of 314 g. A week later, fetal demise occurred. Placental pathology revealed a placental weight of 83 g, an extensive maternal floor infarction, and an extreme velamentous cord insertion 7 cm from the edge of the placental disc, with vessels entering at opposite poles of the placental disc and a single anastomotic bridging vessel on the chorionic plate connecting these two vascular poles. A triphasic umbilical artery waveform may be associated with a premorbid state and severe placental vascular abnormality. We hypothesize that the third and positive component in late diastole is present due to forward flow across the communicating bridging vessel into the contralateral entering vessel.

Background: The objective of the present study was to find out association between aortic isthmus Doppler changes and perinatal outcome in growth restricted fetuses with placental insufficiency.Methods: It is a prospective case control study, cases were 43 pregnant women with fetal growth restriction (FGR) with abnormal umbilical artery (UA) Doppler while 43 pregnant women with FGR but normal UA doppler, matched with period of gestation were taken as control. The direction of blood flow in aortic isthmus studied which may be antegrade, absent or retrograde and correlation between qualitative parameters of umbilical artery, aortic isthmus and ductus venosus were studied. Quantitative parameters, PI and RI were also calculated. Patients were managed as per hospital protocols. Perinatal outcome and any adverse event e.g. stillbirth, neonatal death, respiratory distress syndrome, intensive care unit stay >14 days etc. was noted.Results: The number of intrauterine death (IUD) and still birth was increased in women with absent and retrograde flow in aortic isthmus, 66.7% and 71.4% respectively (p value <0.001). Retrograde blood flow in the aortic isthmus is consistently associated with absent or reverse end diastolic velocity in umbilical artery and ductus venosus.Conclusions: Doppler of aortic isthmus is an additional parameter to assess severity of FGR. It plays an important role in termination of preterm FGR fetuses.
