“…During the earlier peri od of gestation, vitelline artery and vein, and right umbili cal vein can also be noted in the umbilical cord [6], Aber rant umbilical vessels comprise the total aberrances origi nated from all vessels in the umbilical cord, such as hemangioma, varicosity, hematoma, absence [7] or super num erary [8] and discordancy [9] of vessels. Therefore, mass formation related with the extravascular tissue in the umbilical cord such as cystic encasement secondary to edema or degeneration of Wharton's jelly could be ex cluded.…”

“…The developmental origin of the fourth vessel was explained chiefly as the rare persistence of the caudal por tion of the right umbilical vein [ 19], More than four multi ple umbilical vessels was considered to be a secondary change of relevant vessels in vitelline and/or allantoic duct to the chorangiosis and villitis [8,20]. In our 2 cases, the fourth vessel might be the partial persistence of the caudal portion of right umbilical vein because they were proven to be the vein microscopically.…”

Objective: To evaluate the antenatal screening of aberrant umbilical vessels and assess the association of fetal abnormality with these entities. Study Design: 444 pregnant women were studied with routine obstetric ultrasound and Doppler color flow imaging in late second trimester or early third trimester. Fetal growth and anomaly, and the number of umbilical cord vessels were screened. Results: Out of 444 subjects, 3 cases with discordant umbilical artery, 2 with four vessels in the umbilical cord, and 1 with single umbilical artery were detected (1.4%). Fetal anomaly was noted in 2 of 6 cases with aberrant umbilical vessels (33.3%). Conclusion: These results suggest that antenatal screening of umbilical cord vessels is necessary for detection of fetal anomalies.

“…The most common cause of this finding is the persistence of the right umbilical vein . However, 5 or more vessels in the cord, 2 of which are umbilical veins, have mostly been described as a part of conjoined twinning . Therefore, conjoined twins and umbilical cord entanglement in monoamniotic twins are the 2 most important entities in the differential diagnosis of a single proximal umbilical cord.…”

Umbilical vein variations: Review of the literature and a case report of a persistent right umbilical vein

1988

A case of a ligamentum teres formed from an obliterated right umbilical vein is described. It passed to the right branch of the portal vein. The quadrate and left lobes of the liver were not separated by the usual fissure. Very few cases of anomalous umbilical veins or persistent right umbilical veins have been recorded. Of these, several have been recorded only in the umbilical cord, while in others the persistent right umbilical vein has been found intra-abdominally, in an extrahepatic position, and passing directly to the right atrium or to the inferior vena cava. Its presence is generally associated with severe congenital abnormalities, in contrast with the present case. In view of the high incidence of congenital defects associated with aberrant or accessory umbilical veins, when these are detected either in the umbilical cord or in the abdomen by umbilical phlebography, it is suggested that the patient should be carefully investigated for other congenital abnormalities.
