“…Peak flow rate of the three peaks increased with gestational age, which showed linear correlation [12]. The ratio of reverse blood flow of peak A [13], which was the time integral of atrial systolic divided by the entire time integral of forward flow velocity, reflected the pressure gradient between the right atrium and right ventricle end-diastolic. The ratio of reverse blood flow in inferior vena cava depended on the ventricular compliance and right ventricular end-diastolic pressure [14].…”

Objective: This work aims to investigate the application of high definition flow imaging (HD-flow) in fetal hemodynamics, and establish reference range of hemodynamic parameters in fetal with different gestational ages. Materials and Methods: A thousand of normal pregnant women were divided into five groups: 18-22, 23-27, 28-32, 33-37, and 38-40 gestational weeks. Color Doppler flow imaging (CDFI) and HD-flow were adopted to display the heart structure and measure the blood flow velocity. The pulmonary vein display results were scored. The results of HD-flow and CDFI were compared. Results: The catheter peak velocity of fetal mitral, tricuspid, aortic, pulmonary artery, aortic arch, ductal arch, the inferior vena cava, pulmonary vein, and venous catheter increased continuously with the increase of gestational age, showing a linear correlation. HD-flow was superior to CDFI on the display of pulmonary vein in 18-22, 23-27, and 28-32 weeks (p < 0.05), but was not in 33-37 and 38-40 weeks. HD-flow was an accurate positioning method for the pulmonary veins. Conclusion: HD-flow can make accurate evaluation of fetal hemodynamics and the demonstration of low blood flow, such as pulmonary venous, is better than CDFI. Pulmonary veins can be accurately positioned with HD-flow. HD-flow can demonstrate the main blood vessels of the whole fetal circulation and can display the spatial relationship of the blood vessels. It is of important clinical significance in hemodynamic study.

“…It has been suggested that some cases diagnosed in neonates likely began in utero, based on the chronic appearance of the sonographic findings after birth 6 , 7 , 15 . Case reports of fetal renal vein thrombosis support this hypothesis, 4 , 5 , 10 – 13 , 16 , 17 as do cases of fetal IVC thrombosis associated with renal vein thrombosis 18 – 20 . Many of the various case reports of fetal renal vein thrombosis were summarized in a recent review 21 .…”

“…6,7,15 Case reports of fetal renal vein thrombosis support this hypothesis, 4,5,[10][11][12][13]16,17 as do cases of fetal IVC thrombosis associated with renal vein thrombosis. [18][19][20] Many of the various case reports of fetal renal vein thrombosis were summarized in a recent review. 21 We present, to our knowledge, the largest series to date of prenatally diagnosed renal vein thrombosis from a single institution, including 1 case in which progression of the renal and thrombotic process was observed in the fetus over the course of 7 days.…”

We present the sonographic findings of fetal renal vein thrombosis in a series of 6 patients. The mean gestational age at diagnosis was 31.2 weeks. Four cases were unilateral, and 2 were bilateral. The most common findings were renal enlargement and intrarenal vascular calcifications, followed by increased renal parenchymal echogenicity. Inferior vena cava thrombosis was found in 4 patients and common iliac vein thrombosis in 2. Fetal renal vein thrombosis is an uncommon diagnosis with characteristic sonographic findings. The presence of these findings should prompt Doppler interrogation of the renal vein and inferior vena cava to confirm the diagnosis.
