“…Abnormal venous flow, in both the DV (absent/reversed a‐wave) and the umbilical vein (pulsations), is strongly related to perinatal death in pregnancies complicated by fetal hydrops , with perinatal mortality rates as high as 79% . In cases of increased hepatic venous pressure, umbilical venous flow may reverse altogether, leading to placental swelling . It is for these reasons that DV Doppler is performed in all cases of fetal hydrops, and an abnormal waveform should prompt a detailed evaluation of the fetal anatomy, cardiovascular status, and fetal echocardiography .…”

The ductus venosus has a central role in the distribution of highly oxygenated umbilical venous blood to the heart. Its waveform is related to the pressurevolume changes in the cardiac atria and it is therefore important in the monitoring of any fetal condition that may affect forward cardiac function. The cardiovascular parameters that can influence forward cardiac function include afterload, myocardial performance and preload. Decreased forward flow during atrial systole (a-wave) is the most sensitive and ubiquitous finding when any of these parameters is affected. In contrast, decreased forward velocities during end-systolic relaxation (v-wave) are more specifically related to myocardial performance. The ductus venosus pulsatility index alone does not accurately reflect cardiac function, and in cases of suspected fetal cardiac dysfunction, echocardiography is required to identify the underlying mechanism. The role of ductus venosus Doppler in the assessment of fetal growth restriction, supraventricular tachycardia, fetal hydrops, complicated monochorionic twins and congenital heart disease is discussed with these considerations in mind.Abbreviations: AV, atrio-ventricular; CHD, congenital heart disease; DV, ductus venosus; FGR, fetal growth restriction; PIV, pulsatility index for veins; SVT, supraventricular tachycardia; TTTS, twin-to-twin transfusion syndrome. The central role of ductus venosus in fetal cardiovascular assessmentDoppler examination of the fetal venous circulation was introduced into perinatal medicine over 25 years ago to extend cardiovascular functional assessment beyond the capabilities of arterial Doppler. All central and precordial venous vessels share the same flow pattern of forward flow in ventricular systole and diastole and a temporary decrease in forward flow during end-ventricular systole and atrial systole. However, the ductus venosus (DV) has several important characteristics that favor its widespread use in fetal medicine. It is a short vessel with a relatively fixed position, allowing for standardization of the Key messageThe ductus venosus waveform reflects the pressurevolume changes in the heart. Despite the limited specificity of the ductus venosus waveform, its correlation with cardiac forward function makes it of central importance in assessing the overall severity of fetal cardiovascular pathology. Ductus venosus Doppler study has a critical role in directing the clinical management of fetuses at risk of cardiovascular deterioration.ª

“…The umbilical venous Doppler flow pattern is usually described as mildly phasic, low velocity flow. With increases in central venous pressure, umbilical venous flow may reverse altogether leading to placental swelling [33] notching is first seen at end-diastole, corresponding to atrial contraction. In cases of severe congestive heart failure or hydrops fetalis, venous pulsations may be seen [34].…”

Objective:The aim of this study was to evaluate the role of inferior vena cava, ductus venosus, and intrahepatic portion of umbilical vein Doppler in evaluation of cases of nonimmune fetal hydrops. Material and Method:This study was conducted at the Department of Obstetrics and Gynecology, faculty of medicine, Alexandria University on 37 pregnant females in second and third trimester pregnancy selected from the attendees of El-Shatby Maternity university hospital. The cases were allocated into 2 main groups: group 1: twenty seven pregnant women with nonimmune fetal hydrops. Group 2: ten normal pregnant women without non-immune fetal hydrops (control group). We excluded from our study cases of immune fetal hydrops.We studied preload index of inferior vena cava, preload index and A wave of ductus venosus, and intrahepatic umbilical vein maximal velocity. Result: Our results showed the presence of high statistical significant correlation between abnormally elevated preload index of inferior vena cava, ductus venosus and abnormal A wave of ductus venosus and nonimmunefetal hydrops group. There were also high statistical significant correlation between intrahepatic umbilical vein decreased maximal velocity and nonimmune fetal hydrops. These changes of the velocimetry in the Inferior vena cava, Ductus venosus, and Intrahepatic umbilical vein corresponding to changes in cardiac function and could be of value in predicting prognosis and outcome of pregnancy.Conclusion: Doppler velocimetry in the IVC, DV, and intrahepatic portion of UV is a useful tool in the workup of hydropic fetuses.

As the core organ of cardiovascular system, fetal heart plays a very important role. With the development of pregnancy, the early fetal heart rate tends to mature, and the corresponding cardiac function tends to mature and stable. But the fetal heart is very fragile during pregnancy. Various diseases during pregnancy directly lead to fetal heart growth restriction, and even lead to fetal heart function damage. Ultrasound image diagnosis is one of the most important diagnostic methods in medical imaging. It is of great significance to detect the early heart structure of the fetus in gynecology and obstetrics. It can detect the early fetal heart in real time and noninvasively. However, the traditional ultrasonic image detection has many disadvantages in the process of application, such as many noise points, low performance of processing algorithm, which to some extent affects the detection performance of ultrasonic image detection in the detection of fetal heart structure in gynecology and obstetrics. Based on the above problems, this paper proposes an adaptive detection algorithm of superimposed moving image based on ultrasonic image detection, which can accurately extract and analyze fetal heart region when the signal-to-noise ratio of ultrasonic image sequence is low. The average anisotropy algorithm is also proposed innovatively in this paper. In order to predict the structure of fetal heart more accurately, the active heart model combining fetal heart structure and motion information is considered in the actual analysis process. Experiments show that the accuracy error of the algorithm is less than 11 pixels.
