ABSENCE DE LA GELEE DE WHARTON AUTOUR D’UNE ARTERE OMBILICALE

Abstract

Introduction: Wharton's jelly is a mucoid connective tissue, avascular who plays the role of protection vis-a-vis the umbilical vessels avoiding compression. The umbilical arteries devoid of Wharton's jelly are more prone to compression. A complete absence is most often associated with fetal death. Clinical case: We report a case of a newborn in the maternity compiled des Orangers, having one of the umbilical arteries, devoid of Wharton's jelly over a distance of 10 cm from the umbilicus and whose clinical course was satisfactory. Discussion: In the literature, five cases have been reported, and several hypotheses have been discussed: Degeneration of Wharton tissue around the vessels, fusion incomplete coating amniotic mesenchymal umbilical cord during early embryonic development, hypoplastic amniotic coating with secondary loss of Wharton's jelly. In our context, since only one of the two umbilical arteries was not protected and covered by the thick meconium, two hypotheses arise: action thick meconium components of Wharton's jelly. A also discuss the underlying infection related with the absence of Wharton's jelly. Conclusion: The total absence of Wharton's jelly around the umbilical artery or two remains poorly understood, however, biochemical action of the components of meconium on Wharton's jelly or infectious origin can’t be excluded.
