The missing umbilical artery – A case report

Single umbilical artery (SUA) is a condition where one umbilical artery exists. Normally, the umbilical artery contains two umbilical artery and one umbilical vein. The incidence of SUA varies from 0.2% to 0.8%. We present a case of SUA in a term baby with birth weight of 1.7kg delivered by a 28-year-old mother. SUA is a condition which must be kept in mind during histopathological examination since it helps in improving the neonatal and maternal care.

A 22-week stillborn fetus with 47,XXX karyotype had lower mesodermal defects consisting of irregular fusion of the sacral vertebrae, anal agenesis, multicystic dysplasia of a horseshoe kidney, a single umbilical artery, dysplastic ovaries, and uterine hypoplasia. This case provides additional evidence for an association between trisomy X and genitourinary defects including lower mesodermal defects sequence.

BACKGROUND Human umbilical cord contains two arteries and one vein with their tunica intima and tunica media layers. The role of tunica adventitia is fulfilled by Wharton’s jelly, a mucoid connective tissue. The function of Wharton’s jelly is to prevent the vessels from compression and torsion which is essential for foetal development. The purpose of the study was to estimate the importance of Wharton’s jelly in the growth of the foetus. METHODS Umbilical cord tissue collected from each case was immediately put in 10 % formalin for fixation. Slides were then stained with Haematoxylin and Eosin. These slides were then read under light microscopy and measurements were taken using a photomicrograph. Wharton’s jelly area was calculated by subtracting the total vessel area from the umbilical cord area. RESULTS The histological measurements of umbilical vessels include the external diameter, lumen diameter, wall thickness, thickness of tunica intima and tunica media, and the area. The mean area of the umbilical cord was 35.73 ±23.04 mm2 (Mean ± SD) and the mean area of the Wharton’s jelly was 29.74 ± 19.26 mm2. There was a significant difference in the external diameter and wall thickness of the umbilical artery. Analyses showed that there was a significantly (P < 0.01) increased external diameter and wall thickness of umbilical artery in normal cases, compared to single umbilical artery cases. CONCLUSIONS There was a significant positive correlation between the gestational age and the external diameter of the umbilical cord. There was a significant difference in the external diameter of the umbilical cord between SUA cases (4.45 mm) and the other foetuses with normal umbilical cord (6.53 mm). There was a significantly increased external diameter, lumen diameter, wall thickness and area of umbilical vein in normal cases, compared to single umbilical artery cases. There was a significantly increased area of umbilical cord and area of Wharton’s jelly in normal umbilical cord foetuses than foetuses with a single umbilical artery.

A Prospective Study

ABSTRACT Objective Through a prospective study the incidence and neonatal results of patients with persistent right umbilical vein are evaluated. Materials and methods During the period between August 2009 and February 2011, 3,576 low-risk obstetric sonographies were performed by the same technician at four different centers of prenatal diagnosis. Persistent right umbilical vein was diagnosed during a customary ultrasound examination, in the abdominal transverse section used to measure abdominal perimeter. Patients were asked to bring their children several months after delivery for a clinical and sonographic evaluation. Results Persistent right umbilical vein was found in nine fetuses. In one case, it was associated with single umbilical artery. All fetuses had good growth and development. In some children, the postnatal sonography showed the gallbladder toward the left of falciform ligament. Conclusion The incidence of persistent right umbilical vein in this population was of 1:397. We did not find any association with severe malformations as mentioned in the first articles related to this topic. There was only one case with single umbilical artery. All newborns developed normally. The question is raised why, being this anomaly so frequent and obvious, it is not more often diagnosed. Gallbladder position in respect to falciform ligament is a finding to assess. How to cite this article Leal DB, Maggiolini M, Bianchi A.
