“…The incidence of 0.40% (48/12,071) detected in the current study seems to be compatible with the reported incidence of RSLT during neonatal ultrasonography (0.08–0.46%)22, 23, 24, 25, 26, 27, 28 and the prevalence of the condition in the adult population 4, 14, 15, 29. To compare and discuss various observations about the anatomy of the liver, clear definitions and knowledge about basic vascular anatomy are required.…”

ObjectiveTo obtain information about the basic biliary anatomy of livers with right-sided ligamentum teres (RSLT).Summary of background dataRSLT is a relatively rare anomaly with a reported incidence of 0.2–1.2%. Although the portal/hepatic venous and arterial anatomy of livers with RSLT has already been established, the biliary architecture of such livers remains unclear.MethodsRSLT was detected in 48 patients during 12,071 consecutive image readings (0.4%). Of these patients, the cholangiograms of 46 patients were analyzed, and their intrahepatic biliary tree confluence patterns were classified.ResultsThe following four unique biliary confluence patterns were identified in livers with RSLT: the symmetrical type (23/46), independent right lateral type (13/46), total left type (6/46), and total right type (1/46). Analyses of the portal and arterial branching patterns of these livers showed that there were no correlations between their biliary confluence patterns and their portal or arterial ramification patterns.ConclusionThe basic biliary architecture of livers with RSLT was clarified. As the RSLT patients' anomalous biliary confluences differed from those seen in normal livers and were difficult to predict, preoperative cholangiography should be performed prior to complex hepatobiliary surgery involving livers with RSLT to ensure patient safety.

“…Also, the intrahepatic-must be distinguished from the extra hepatic variant and the agenesis of the DV must be suspected (Figure 4) [12]. In the reported case, the azygos vein is markedly dilated and has a diameter greater than that of the aorta because it collects the blood issued from the lower body but also the blood from the right umbilical vein that bypasses the liver and drains directly into the azygos vein.…”

We report on the case of a fetus in whom a prenatal ultrasound performed at 22 weeks of gestation allowed the diagnosis of a double anomaly of the systemic venous return, with a persistent right umbilical vein and the agenesis of the inferior vena cava with azygos continuity.The fetus showed also a large umbilical hernia and a right sided microphtalmia. Fetal growth was normal. Genetic anomalies were excluded by karyotype and CGH array. Cesarean section was performed at 39 weeks of gestational age for breech presentation. The neonate adapted well. Post-natal examination confirmed pre-natal diagnosis. Thoraco-abdominal CT-scan performed at 8 days of age showed additional right upper lobe bronchial atresia with relative hypoplasia of the right pulmonary artery and right hepatic lobe hypotrophy. It also showed a short segmental infra diaphragmatic aplasia of the vena cava with dilation of the azygos vein running along the homolateral diaphragmatic coupola that drained into superior vena cava and malposition of the mesenterial vessels without any intestinal malrotation. Anomalies of the fetal cardinals and umbilical veins are the result of early abnormal venous system development in the embryo, the etiology of which is unknown. Usually, abnormal systemic venous return only affects one vessel. The presence of a double anomaly as described in this case is exceptional.A persistent right umbilical vein is reported in 0.2 to 0.4% of antenatal screening. The variant with intrahepatic transition is the most frequent and isolated form. The exceptional, form with hepatic bypass, is commonly part of a polymalformative syndrome. Agenesis of the inferior vena cava (IVC) with azygos continuity is a rare anomaly (0,2-3% of antenatal screening). Its significance relates to its frequent association with complex congenital heart diseases. The prognosis of anomalies of cardinals and umbilical veins depends on the presence of associated cardiac and extra cardiac malformations that might impact prenatal counseling and parental decision to continue or interrupt pregnancy. Careful repeated pre and post-natal evaluation is necessary to exclude polymalformative syndrome despite of normal molecular genetic examination.

Prenatal Diagnosis of Persistent Right Umbilical Vein Using Three-dimensional Sonography with Power Doppler

Abstract: PRUV is a common vascular anomaly that is easy to be overlooked. Reconstruction of the portal system in the affected fetuses using 3D ultrasound facilitated the identification of the DV. If the DV is present, and other anomalies are excluded, the fetus with PRUV has a good outcome.
