Abstract

Abstract: The objective of our study was to appraise the incidence and significance of persistent right umbilical vein (PRUV), the most common foetal venous aberration. Based on a south Indian antenatal cohort, we identified 23 cases of PRUV amongst 20, 452 foetuses of consecutive pregnancies, from 2009 to 2014, yielding an incidence of 1 in 889 total births (0.11%). The median maternal age was 24 (IQR, 22–26) years, and median gestational age at diagnosis was 23 (IQR, 22–24) weeks. Intrahepatic drainage of PRUV was seen in 91.3% cases. In three cases (13%), ductus venosus was absent. In 52.2% of the cases, additional major abnormalities were observed – predominantly cardiovascular (39.1%). The common minor marker was single umbilical artery (13%). The karyotype was found to be normal in six cases (26%) which underwent invasive testing. When associated anomalies were inconsequential or absent, the postnatal outcome was good, which reflected in 60.9% of our cases.
