A case of prenatal diagnosis of single umbilical artery due to thrombosis diagnosed by the ultrasound finding of “wink-sign”

AbstractObjectivesUmbilical artery thrombosis is a significant umbilical cord condition that is associated with adverse pregnancy outcomes. However, no consensus has been reached regarding how umbilical artery thrombosis should be diagnosed or managed because of its rarity and the difficulty associated with an antenatal diagnosis.Case presentationHere, we describe a case involving decreased fetal movement and non-reassuring fetal status (NRFS) in which acute umbilical artery thrombosis was prenatally diagnosed. Transabdominal ultrasound showed that the cross-section of the umbilical cord had one normal artery and a small deformed echogenic area. A characteristic ultrasound finding known as the “wink sign” contributed to the prenatal diagnosis.ConclusionsEvaluation of the umbilical cord enabled the estimation and facilitated the subsequent antenatal management.

Single Umbilical Artery

The case of prenatal ultrasound diagnosis of single umbilical artery aneurysm is presented. During ultrasound examination at 21 weeks of gestation several anomalies in the umbilical cord were detected: the umbilical right artery was missing and dilatation of the umbilical artery with a diameter 10 mm close to fetus. With colour Doppler and pulsed Doppler was demonstrated arterial turbulent flow in the aneurysm. Prenatal diagnosis of the single umbilical artery aneurysm was made. Other fetal measurements were normal. The diameter of the aneurysm increased throughout the pregnancy till 16 mm at 33 weeks of gestation. Cesarean section was performed at 34 weeks with baby weight 2150 g. The post-delivery examination of the umbilical cord confirmed the prenatal diagnosis. No chromosomal abnormalities were found. After six months the baby is alive and well.

Objective Thrombosis of umbilical artery is a rare condition. The diagnosis is established commonly in the third trimester after detection of fetal distress or intrauterine growth retardation, or could be established after delivery. Also, the management of the condition is conflicting after the diagnosis. Case(s) Here we reported an umbilical artery thrombosis case that was diagnosed in the second trimester after referral for an umbilical cord cyst. After the diagnosis at 24th week of pregnancy, she had been followed up weekly. She had been delivered electively at the 34th week of pregnancy uneventfully. The diagnosis was confirmed postnatally. Conclusion The prenatal diagnosis of umbilical arterial thrombosis is so important to prevent perinatal morbidity. When umbilical cord cysts are detected, further evaluation is required in terms of umbilical artery thrombosis.

Umbilical Cords

Background: A right-sided umbilical cord twist is associated with the presence of a single umbilical artery, congenital malformations and placenta praevia. Methods: It was an observational study. Data was collected from 137 umbilical cords, all from live births and their patient records. The gestational ages ranged from 28 weeks to 41 weeks. The umbilical cords were categorized into right or left, based on the direction of twist. The independent sample T test and the Chi square test were used to analyze the differences between groups. Results: The prevalence of left twist was 84%. Right twist was significantly associated with a larger Hyrtl’s anastomosis (p=0.029) and gestational diabetes (p=0.027). Conclusion: Two previously unreported associations with right twist of the umbilical cord, gestational diabetes and an increase in the diameter of Hyrtl’s anastomosis, were noted in the present study.
