Abstract: Review of present knowledge about fetal growth, and clinical and ultrasonography diagnosis of Intrauterine growth restriction by means of 2D and 3D. The review included the diagnosis of type of IUGR and the study of fetal deterioration (Chronic Tests and Acute Markers). Also the obstetrics management.

“…Clinically, the UA velocity waveforms are most commonly evaluated in terms of the UA pulsatility index (1,5), defined as the ratio of peak-topeak velocity to the mean velocity over a cardiac cycle; this is widely viewed as a surrogate for downstream fetoplacental vascular function and thus oxygenation of the fetus (1). This conclusion is broadly valid because pulsation in the UA is correlated with defects in the fetoplacental vessels (7,36) and related to the downstream placental vascular resistance (1). However, a major limitation of measuring pulsatility is that it varies substantially between placental and fetal ends of the umbilical cord (52).…”

Abnormally pulsatile umbilical artery (UA) Doppler ultrasound velocity waveforms are a hallmark of severe or early onset placental-mediated intrauterine growth restriction (IUGR), whereas milder late onset IUGR pregnancies typically have normal UA pulsatility. The diagnostic utility of these waveforms to detect placental pathology is thus limited and hampered by factors outside of the placental circulation, including fetal cardiac output. In view of these limitations, we hypothesized that these Doppler waveforms could be more clearly understood as a reflection phenomenon and that a reflected pulse pressure wave is present in the UA that originates from the placenta and propagates backward along the UA. To investigate this, we developed a new ultrasound approach to isolate that portion of the UA Doppler waveform that arises from a pulse pressure wave propagating backward along the UA. Ultrasound measurements of UA lumen diameter and flow waveforms were used to decompose the observed flow waveform into its forward and reflected components. Evaluation of CD1 and C57BL/6 mice at embryonic day (E)15.5 and E17.5 demonstrated that the reflected waveforms diverged between the strains at E17.5, mirroring known changes in the fractal geometry of fetoplacental arteries at these ages. These experiments demonstrate the feasibility of noninvasively measuring wave reflections that originate from the fetoplacental circulation. The observed reflections were consistent with theoretical predictions based on the area ratio of parent to daughters at bifurcations in fetoplacental arteries suggesting that this approach could be used in the diagnosis of fetoplacental vascular pathology that is prevalent in human IUGR. Given that the proposed measurements represent a subset of those currently used in human fetal surveillance, the adaptation of this technology could extend the diagnostic utility of Doppler ultrasound in the detection of placental vascular pathologies that cause IUGR. Here, we describe a novel approach to noninvasively detect microvascular changes in the fetoplacental circulation using ultrasound. The technique is based on detecting reflection pulse pressure waves that travel along the umbilical artery. Using a proof-of-principle study, we demonstrate the feasibility of the technique in two strains of experimental mice.

Aims: The primary aim of this study was to compare circulatory changes in the fetal brain under certain pathological conditions with alterations in fetal behavior. Patients and methods: A prospective longitudinal cohort study on fetal behavior of fetuses from singleton pregnancies between the 28 th and 38 th gestational week in the period from March 2009 to October 2011 was undertaken. There were 596 fetuses in the high-risk group and 273 fetuses in the low-risk group. Elevated umbilical artery Doppler pulsatility index and reduced middle cerebral artery pulsatility index obtained in the absence of fetal movements were considered abnormal. The Kurjak Antenatal Neurodevelopmental Test (KANET) was used to assess fetal behavior. Results: Statistically signifi cant differences in the distribution of normal, abnormal, and borderline KANET scores between low-risk and high-risk groups were found. Furthermore, 596 fetuses from the high-risk group were subdivided into subgroups according to the risk factor. The largest proportion of abnormal KANET scores (23.9 % ) was in the subgroup of fetuses whose mothers had an offspring diagnosed with cerebral palsy (23.9 % ), followed by the proportion of borderline KANET scores in the subgroup of fetuses from febrile mothers (12.7 % ). Fetal behavior was signifi cantly different between the normal group and the following subgroups of fetuses: fetal growth restriction (FGR), gestational diabetes mellitus, threatened preterm birth, antepartal hemorrhage, maternal fever, sibling with cerebral palsy, and polyhydramnios. Conclusions: A new clinical application of the KANET test in early identifi cation of fetuses at risk for adverse neurological outcome was demonstrated.
