Wharton's jelly absence: a possible cause of stillbirth

Abstract

The umbilical cord is a structure that provides vascular flow between the fetus and the placenta. It contains two arteries and one vein, which are surrounded and supported by gelatinous tissue known as Wharton's jelly. There are many umbilical cord abnormalities that are related to the prognosis of fetus survival and birth weight. The authors report a case of umbilical cord constriction due to the localized absence of Wharton's jelly, which was undiagnosed antenatally and had a fatal outcome. A review of the association between the absence of Wharton's jelly and an unfavorable pregnancy outcome was undertaken.
