Este texto tem a finalidade de revisar as características anatômicas e funcionais do ducto venoso fetal, bem como a importância de sua avaliação ultra-sonográfica pré-natal.The ductus venosus is a blood vessel unique to the fetal circulation which functions as a shunt between the umbilical vein and inferior vena cava. It continues for about 2–3 cm within the layers of the lesser omentum, running in a groove between the left and caudate lobes of the liver. As some of the malformations can be explained by chromosomal alterations we present, in Table 2, their prevalence for each type of malformation according to the respective fetal outcome. A summary of the conditions diagnosed at prenatal or postnatal ultrasonographic evaluations or postmortem autopsies is shown in Table 1.

Near the porta hepatis, it gives off several large intrahepatic branches to the fetal liver and anastomoses with the left branch of the portal vein. The pressure gradient between IVC and umbilical vein varies with the phase of the heart cycle, resulting in changes in DV blood velocity.

For the extrahepatic connection, the umbilical venous drainage can be detected by the abnormal course of the intra-abdominal umbilical vein on gray-scale sonography, while the intrahepatic connection requires color flow mapping of the fetal portal circulation in various planes of evaluation [17]. 2008;31(3):256-260.

When the DV is absent, the umbilical blood flows from the umbilical vein through an aberrant vessel that may be extrahepatic, bypassing the liver, or intrahepatic, via the portal venous system [5], [6], [7]. The ductus venosus agenesis (DVA) is a rare condition with a variable prognosis that relies partly on the presence of associated conditions.

Of the fetuses, 60.8% (188/309) had an extrahepatic umbilical venous drainage while 39.2% (121/309) presented an intrahepatic connection. Indicaciones. This blood passes into the right ventricle and is then shunted directly into the descending aorta from the proximal left pulmonary artery via the ductus arteriosus. The ductus venosus connects the portal sinus with the confluence of the hepatic veins into the inferior vena cava.

Concerning the STROBE statement, it was seen a higher proportion of high risk of bias in the items 2 and 4. Your documents are now available to view. Fetal circulation is unlike adult circulation as it uses physiological shunts to carry oxygenated blood to tissues and bypass developing organs. This oxygenated blood then passes through the . Ductus venosus agenesis and fetal malformations: what can we expect? 9WbBDWl:V Before this, the lung's function is taken over by the placenta, which is the oxygen-transfer organ during fetal life.

Furthermore, although informed consent is assumed when presenting a case report, the included studies did not provide that information.

In this case, the umbilical vein connects to the portal sinus as usual but without giving rise to the DV [6].

For each study, we have recorded the name of the author, year, study design, gestational age, number of cases described with DVA, umbilical vein connection, pre-natal imaging findings, gestational age at delivery or pregnancy termination, fetal outcomes (intrauterine fetal death, neonatal death or survival), post-natal imaging findings, post-mortem findings, associated congenital anomalies and karyotype. The ductus venosus (DV) is a shunt between the intra-abdominal umbilical vein and inferior vena cava (IVC) that directs well-oxygenated blood preferentially through the foramen ovale into the left heart, thus feeding the coronary and . With the widespread use of ultrasonographic techniques and their improvement over the years, a more careful examination of the fetal circulation, particularly the umbilical and portal venous malformations, is now performed prenatally. Rudolph CD, Meyers RL, Paulick RP, Rudolph AM. However, to overcome this possible limitation and despite the heterogeneity of the included studies, we used two different and validated methods for a critical assessment of the risk of bias. /Contents 21 0 R Shen O, Valsky DV, Messing B, Cohen SM, Lipschuetz M, Yagel S. Shunt diameter in agenesis of the ductus venosus with extrahepatic portosystemic shunt impacts on prognosis. In six (3.2%) cases the extrahepatic drainage was referred to only as “going to the heart”, and two (1.1%) cases were only referred to as an “extrahepatic shunt” without characterization of the structure involved. J Ultrasound Med 1992;11:111–3.

Ductus venosus (DV) is a narrow, trumpet-shaped vessel which is seen in the fetal liver connecting the umbilical vein directly to the caudal inferior vena cava or distal left hepatic vein.The vessel plays a critical role in the fetal circulation by shunting oxygenated and nutrient-rich umbilical venous blood from the placenta to the brain and myocardium, bypassing the fetal liver. lO\G4j&@;`9Hlf!#`t"3Z1OD 13 0 obj Por meio dele, o sangue rico em oxigênio, proveniente da veia umbilical, chega ao átrio direito e a partir daí, pelo forame oval, ganha o átrio esquerdo e a circulação sistêmica, favorecendo o fluxo para órgãos vitais como o cérebro fetal.

The assessment of DV blood flow is an integral part of the first trimester screening since it was demonstrated that the abnormal flow in this vessel is associated with an increased risk for chromosomal abnormalities, cardiac defects and adverse perinatal outcome both in singletons and twin pregnancies [18], [19], [20], [21], [22], [23]. To improve the reliability of this analysis, any discrepancy or disagreement in the classification of the methodological quality was resolved through discussion or intervention of the leading investigator.

An evaluation is made of the possibility of assessing foetal anatomy and measuring nuchal translucency (NT) from the deferred study of the volume captured using three-dimensional (3D) ultrasound. In the fetus, the ductus venosus (Arantius' duct after Julius Caesar Aranzi) shunts a portion of umbilical vein blood flow directly to the inferior vena cava. Studies were eligible if they provided data on DVA. Furthermore, this paper adds value in oriented clinical information specifically addressing what to expect when faced with DVA in association with fetal malformations. 18 (6): 598.

Cardiol Res. do not contaminate the ductus venosus flow with the flow from the fetal inferior vena cava, for this the Doppler sample should be small (0.5-1 mm) the sweep speed should be high (2-3 cm/s) so that the waveforms are spread allowing better assessment of the A wave.
