“…Similar observations were noted by Baran et al [ 47 ], who reported that fetuses with developmental anomalies had an average DV-PI value of 1.22 m/s [ 47 ]. Additionally, in one of the cohort examinations regarding DV-PI reference values, it was indicated to interpret venous flow rates below 0.93 m/s and above 1.22 m/s as abnormal [ 48 ], which is compatible with our observations in this study. Likewise, the inclusion of the DV-PI parameter during ultrasound examination is a significant factor that increases the rate of heart defect diagnosis in a fetus [ 49 ].…”

The goal of the study was to assess changes in parameters based on ultrasound examinations—these were Crown Rump Length (CRL), Nuchal Translucency (NT), Fetal Heart Rate (FHR), and Pulsatility Index for Ductus Venosus (DV-PI)—in the first trimester of pregnancy in women in which there was a natural initiation of the pregnancy due to spontaneous ovulation, women in which the pregnancy was initiated as a result of stimulated ovulation, as well as in the group in which pregnancy was achieved through the use of In-Vitro Fertilization (IVF)-assisted reproduction. A total of 1581 women became pregnant without the use of assisted reproduction methods. Out of 283 pregnancies, in 178 patients, induced ovulation was utilized. Next, 137 women had sexual intercourse and became pregnant; 41 of them became pregnant through Intrauterine Insemination (IUI) as a result of Artificial Insemination by Husband (AIH), and 13 became pregnant after Artificial Insemination by Donor (AID). The third group consisted of 105 women subjected to Controlled Ovarian Hyperstimulation (COH). In this group of pregnant women, 53 pregnancies were resultant of Intracytoplasmic Sperm Injection (ICSI), and 52 pregnancies were the result of Intracytoplasmic Morphologically selected Sperm Injection (IMSI). The obtained results did not indicate that the chosen method of fertilization or the chosen ovulation method had a statistically significant effect on the development risk of congenital heart or non-heart defects in the fetus.

“…Inclusion criteria were: ( 1 ) pregnancies with optimal visualization of the DV using a wideband color Doppler technique [advanced dynamic flow (ADF)]; ( 2 ) eventual Apgar score ≥8; ( 3 ) birth weight ≥2500 grams; ( 4 ) measurements taken from a single optimal waveform after obtaining 4 to 5 consecutive uniform Doppler velocity waveforms in the tracings with 2-3 cm/s sweep speed; ( 5 ) patients with normal amniotic fluid index; and ( 6 ) patients with normal screening tests.…”

“…The “S” and “D” peaks correspond to the maximum and “v” and “a” nadirs correspond to the minimum intra-atrial pressure, which accelerates or decelerates the forward flow in DV throughout a cardiac cycle ( Figure 1 , 2 , 3 , 4 , 5 , 6 , 7 , Video 1 , 2 , 3 ). The flow in DV is assessed by either qualitatively observing the spectral pulsed Doppler (PD) flow and checking the “a” nadir in the waveform to assess if it is “reversed” or “not”, and or quantitatively comparing the measurements with published reference ranges for each gestational week of pregnancy ( 2 , 3 , 4 , 5 ).…”

Objective: Ductus venosus blood flow velocity measurements are mandatory in many clinical indications. The evaluation of the flow is performed either by comparing results with general reference tables or by qualitative assessment of the “a” flow, in regard to reversed or absent flow in the spectral waveforms. The aim was to develop normal reference ranges in low-risk pregnancies in our population. Material and Methods: Measurements of flow velocities (S, v, D, a) and indices (pulsatility index for veins, peak velocity index for veins, a/S, S/a) were performed by a single experienced specialist in 1279 singleton, uncomplicated pregnancies between 11 and 40 weeks gestation. The absolute flow velocities (S, v, D, a, VmPeak) and indices were obtained from spectral waveforms using the equipment producer’s inbuilt system. The still images were stored in the picture archiving and communication system. Results: The predicted reference ranges of the ductus venosus blood flow velocities according to the gestational age are shown in tables and graphics. Predicted reference curves based on the 5th and 95th percentiles according to gestational week were plotted and are given in tables and figures. Conclusion: Normal reference ranges for absolute flow velocities and indices were calculated from a population of uncomplicated pregnancies attending a tertiary care center. The measurements were made from both the classic patterns of the waveforms and also considered variants of the spectral waveforms, which have recently been reported, for the first time in the medical literature.

“…6 The Pulsatility Index (PI) and Resistivity Index (RI) of the Ductus Venosus (DV) have become a common ultrasonographic measurement during pregnancy. 9 The importance of these doppler indices has been the topic of ongoing debate in the literature, and its reference value has not yet been identified in Vietnam among the normal population.…”

Prenatal doppler ultrasound of the ductus venosus plays an important role in the evaluation of fetal circulation and fetal heart function. We aimed to establish the percentile of Resistivity Index (RI) and Pulsatility Index (PI) of the Ductus Venosus (DV) among normal Vietnamese fetuses with a gestation from 22 to 37 weeks in a cohort study. Normal Vietnamese fetuses with a gestation ranging from 22 to 37 weeks were examined in a cohort study. The PI and RI were recorded from the DV. We analyzed 640 participants who all fulfilled the inclusion and exclusion criteria of our study. Results: There was a significant correlation between RI, PI and gestational age as shown with the equations y = 0.077x – 0.003x2 + 3.493e - 5x3 (r=0.97) and y = 0.106x – 0.004x2 + 4.5e - 5x3 (r=0.94), respectively. A centile module was constructed for the DV RI and PI indices among normal Vietnamese fetuses with gestation from 22 to 37 weeks.
