Ductus venosus Doppler in the assessment of fetal cardiovascular health: an updated practical approach. Ahmet A. Baschat, The Johns Hopkins Center for Fetal Therapy, Department of Gynecology and Obstetrics, The Johns Hopkins Hospital, 600 North Wolfe Street, Nelson 228, Baltimore, MD 21287, USA.

Introduction. The ductus venosus describes the vitelline blood vessel lying within the liver that connects (shunts) the portal and umbilical veins to the inferior vena cava and also acts to protect the fetus from placental over-circulation. Postnatally this shunt functionally closes (93% of infants at 2 weeks) then structurally closes

Accordingly, ductus venosus Doppler is useful in the management of conditions that put the fetus at risk for cardiovascular deterioration.


Objective: To evaluate the ductus venosus hemodynamic parameters in 31 – 40 weeks gestation normal fetus in the Paki-stani population using Doppler ultrasonography. Material and methods: In a standardized protocol 106 pregnant women (31 to 40 gestation weeks) were scanned.

Ductus Venosus. The ductus venosus pulsed Doppler waveform has been shown to be abnormal in fetuses with Down syndrome and other chromosomal defects who are examined during the first-trimester of pregnancy. This is the ductus venosus that has been isolated because the color Doppler velocity setting is higher than the venous blood flow in

A marked difference in blood flow velocities between the umbilical vein and ductus venosus can be recognized with color Doppler. The 3–4 times higher flow velocity in the ductus venosus causes aliasing, which appears as an area of color reversal (Figs. 16.5, 16.6).

Ductus venosus is the most accurate tool to interprete both fetal cardiac function and myocardial hemodynamics.101516 There was only one study about the relation between ductus venosus Doppler and amniocentesis in the published literature.

The sphincter-like ductus venosus (DV) is an important regulator of fetal circulation. It carries the oxygenated blood from the umbilical vein to the inferior vena cava and foramen ovale, thus bypassing the hepatic circulation.

Aug 01, 2016 · The fetal ductus venosus measurement is part of the fetal dopplers 76820/796821 and is not billed separately. This is different from a fetal umbilical vein doppler (also called umbilical varix), which is an unlisted code 76999.

Patient May Be Responsible for Ductus Venous Doppler Payment. Published on Thu Aug 11, (a ductus venosus ultrasound should only be performed between 11-13 weeks gestation), you could perhaps add a modifier 22(Increased procedural service) to the NT scan code. Reader Question: Patient May Be Responsible for Ductus Venous Doppler Payment

In the assessment of ductus venosus flow the gestation should be 11 +0 to 13 +6 weeks and the CRL 45-84 mm. The fetus should not be moving. The magnification of the image should be such that the fetal thorax and abdomen occupy the whole screen.

The waveform is contaminated from the adjacent veins if the pulsed Doppler sample is:. large (more than 1.0 mm). not placed exactly on the ductus venosus.

Ductus venosus doppler: Oxygen rich blood from the maternal circulation enters to the foetus via the Umbilical vein. The umbilical vein ascends the foetal abdomen and drains into the left portal vein and the IVC via Ductus venosus.

medical Definition of ductus venosus. : a vein passing through the liver and connecting the left umbilical vein with the inferior vena cava of the fetus, losing its circulatory function after birth, and persisting as the ligamentum venosum of the liver.

As with all Doppler waveform patterns, there is a transitional phase of ductus venosus reversed flow. Intermittent reversed flow in the ductus venosus may occur from 2 to 57 days. Once reverse flow is constant, it may persist from 1 to 23 days before delivery is mandated by non-reassuring fetal testing 35 .

Jan 05, 2011 · Morning, Can anyone guide me to the most appropriate cpt code to check the ductus venosus in a fetus. I am leaning towards fetal doppler and or echo codes 76820-76828..however I just can’t find the appropriate description showing this particular area of the fetal cardiovascular system.

The upper panel shows color Doppler flow pattern with aliasing related to high velocity, which guides the placement of the Doppler sample volume ( horizontal arrow ).

Pulsed Doppler sampling from the interior vena cava, the ductus venosus or the hepatic veins can be achieved in longitudinal planes. The next plane, the four-chamber view, is considered as the most important, since it allows an easy detection of numerous severe heart defects.

Doppler evaluation of the fetal ductus venosus has increased our depth of understanding of many fetal conditions. The ductus venosus has an important role in the regulation of nutrient partitioning in the fetus.Alterations in cardiac afterload, contractility compliance, intravascular volume status, and heart rate may significantly impact on the ductus venosus flow velocity waveform.


ductus venosus allows oxygenated blood from the placenta to bypass the liver. In cases where Doppler abnormalities exist because of fetal growth restriction, blood flow in the ductus venosus …

The time of functional closure of the ductus venosus was taken as the day on which blood flow was no longer detected in the ductus venosus by colour Doppler image, and confirmed by finding no measurable blood flow for two days.

Ductus Venosus Doppler US. Doppler waveforms of the ductus venosus represent the physiologic status of the right ventricle. Abnormalities in the fetal venosus circulation reflect central cardiac failure. The normal Doppler waveform is characteristically biphasic. The first peak is the highest and corresponds to ventricular systole (S wave).

The ductus venosus is a blood vessel functioning exclusively in the fetal circulation. According to many reports it was described for the first time by Giulio Cesare Arantius (Bologna 1530–1589) Ductus venosus: a longitudinal Doppler velocimetric study of the human fetus.

Aliasing at the isthmus of the ductus venosus during color doppler interrogation is thought represent high laminar velocity and “possibly vortices rather than turbulent flow” (1). Diameter < 1/3 of umbilical vein and this accelerates blood flow velocity (maximum inner width of narrowest portion = 2 mm).
