ABSTRACT

Wharton's jelly is a specialised tissue which surrounds the vasculature within the fetal umbilical cord. We present the case of a 42-year-old woman who gave birth to a female infant via emergency caesarean section. At the time of delivery, absence of Wharton's jelly was noted. This finding was confirmed by histological examination. Emergency caesarean section was necessitated due to a fetal bradycardia, and of note, the patient had presented twice prior to this with reduced fetal movements.

ABSTRACT

Los quistes de cordón umbilical aparecen en el 3% de los embarazos. Se clasifican en pseudoquistes y verdaderos quistes. La mayoría de los quistes diagnosticados durante el primer trimestre de gestación carecen de significación patológica, pero el 13% puede presentar alteraciones estructurales, y cuanto más persistan a lo largo del embarazo más aumenta el riesgo de las mismas. Estas anomalías son más frecuentes si el quiste se sitúa cerca de la inserción fetal o placentaria, son excéntricos y son múltiples. Cuando son diagnosticados en el segundo y tercer trimestre pueden llegar a asociar hasta en un 50% de los casos anomalías estructurales y cromosómicas. El uraco es una estructura que conecta la cúpula de la vejiga a la pared abdominal anterior, a nivel del ombligo. Durante el desarrollo temprano es un tubo permeable, pero posteriormente se oblitera, quedando un cordón de tejido sólido. Persiste en 1/150 000 recién nacidos. Según a que nivel persista el uraco se clasifica en: uraco permeable, quiste, seno o divertículo. El diagnóstico se realiza por ecografía. Se puede realizar fistulografía previa a la cirugía. A veces pueden ser necesarias otras pruebas de imagen. El tratamiento debe ser quirúrgico y precoz, por riesgo de infección local o del tracto urinario, sepsis y degeneración maligna (AU)


Umbilical cord cysts occur in 3% of pregnancies. They are classified as true cysts and pseudocysts. Most cysts diagnosed during the first trimester of pregnancy have no pathological significance, but 13% may have structural alterations, and if they persist throughout pregnancy increases the percentage. These abnormalities are more frequent if the cyst is close to the fetal or placental insertion, are eccentric and multiple. When they are diagnosed in the second and third quarter, they may associate up to 50% structural and chromosomal abnormalities. The urachus is a structure that connects the bladder to the anterior abdominal wall, at the navel. During the early development is a permeable tube but subsequently obliterated, leaving a solid cord tissue. It persists in 1/150 000 newborns. According to the level of the persistent urachus it is classified into patent urachus, cyst, sinus or diverticulum. The diagnosis is made by ultrasound. Fistulography can be performed before surgery. The abdominal CT scan or MR may be needed to confirm the diagnosis. Treatment should be surgical and prompt, to avoid the risk of local infection, or urinary infection, sepsis and malignant degeneration (AU)
