“…A higher incidence of small‐for‐gestational‐age (SGA) neonates has been found when this adaptive dilatation has not been observed4. It is therefore not surprising that pregnancies with SUA are often classified as at risk because the overall perinatal mortality rate has been estimated to be as high as 5–20%6, 7.…”

“…A fetal single umbilical artery (SUA) is a common congenital malformation with a reported overall incidence between 0.2 and 2.0% [1,2,3,4]. This ultrasonographic finding is associated with autopsy-confirmed congenital malformations spanning all organ systems [5] as well as chromosomal abnormalities [6,7].…”

Introduction: The aim of this study was to determine if laterality of an absent umbilical artery (AUA) is associated with specific sonographic findings, chromosomal defects or postpartum birth defects. Materials and Methods: In this retrospective cohort study, ultrasound reports and medical records of patients who received an obstetric ultrasound at the University of Iowa Hospitals and Clinics with an identified laterality of the AUA from 1989 to 2007 (n = 405) were reviewed. Rates of sonographic abnormalities between fetuses with a right versus left AUA were compared using Fisher’s exact test. Adjustments for confounding were made using logistic regression modeling. The significance level was set at 0.05. Results: Right AUAs on ultrasound demonstrate higher unadjusted rates of ultrasound abnormalities with a higher percentage of fetuses with >1 additional abnormality (51.1 vs. 37.0%; p = 0.0043). The left AUA group had a significantly higher percentage of isolated AUA (63.0 vs. 48.8%; p = 0.004). In a multivariate analysis, a sonographic right AUA was significantly associated with gastrointestinal (GI) and genitourinary (GU) abnormalities. No other ultrasonographic and umbilical artery Doppler abnormalities, chromosomal defects or postpartum birth defects were significantly associated with a specific laterality of the AUA. Discussion: Our study identified a significant association between a right AUA and concomitant fetal GI and GU abnormalities. Contrary to previous reports, we conclude that laterality of the AUA may prove to be an easily identified early marker of fetal abnormalities.

“…In almost 50% of the cases, SUA is associated with other anomalies, (Benirschke and Kaufman, 2006) most frequently of the genitourinary system (renal anomalies; Macpherson, 1991;Cristina et al, 2005). SUA is furthermore correlated with placental abnormalities (Benirschke and Kaufman 2006) and with adverse pregnancy outcome, namely preterm delivery, low birth weight, perinatal mortality and growth retardation (Bjoro et al, 1985;Gornall et al, 2003).…”

Umbilical cord anomalies are more frequent in twins after assisted reproduction

BACKGROUND: The objective of this study is to analyse differences in cord characteristics between naturally conceived twins and twins born after assisted reproduction. METHODS: Between 1985 and 2004, the East Flanders Prospective Twin Survey (EFPTS) registered 4159 twin pairs. We compared cord characteristics between 2119 naturally conceived dizygotic (DZ) twin members and 2243 DZ twin members originating from assisted reproductive technologies (ART). Data were adjusted for intra-twin correlation, year of birth, maternal age, gestational age, parity, sex of the child and number of placentas. RESULTS: Marginal cord insertion, velamentous cord insertion and single umbilical artery (SUA) occur more frequently in twins following infertility treatment (P < 0.001). The incidence of velamentous cord insertion increases proportionate with 'invasiveness' of reproductive techniques: 3.6% in naturally conceived twins versus 5% in twins after artificial induction of ovulation (AIO) [odds ratio (OR) 1.45; 95% confidence interval (CI) 0.99-2.11], 7.4% in twins after IVF (OR 1.49; 95% CI 1.26-1.77) and 10.4% in twins after ICSI (OR 1.31; 95% CI 1.14-1.51). SUA has the highest incidence in twins after AIO: 1.9% compared with 0.6% in naturally conceived twins (OR 3.19; 95% CI 1.66-6.11). CONCLUSIONS: Umbilical cords of twins born after ART have more pathologic characteristics when compared with cords of naturally conceived twins.
