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.

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.

AbstractThrombosis of both umbilical arteries is a rare condition, less common than venous thrombosis. They cause a lot of complications during and after delivery. Umbilical artery thrombosis is associated with both maternal predisposing factors and cord abnormalities and is commonly seen in male fetuses. Presenting symptoms are those of intrauterine growth retardation. Ultrasound abdomen and Doppler flow studies are useful in diagnosing this condition. The prognosis is very poor. Histopathological examination is helpful for confirmation. We present a case of both umbilical arteries thrombosis of a female fetus in a twin gestation causing fetal demise.

Despite the rapid technological advance, the expansion of prenatal ultrasound diagnosis, as well as the accumulation of experience by both domestic and foreign experts, prenatal recognition of true knots of the umbilical cord causes significant difficulties. Three cases of successful ultrasound diagnosis of true knots of the umbilical cord and brief review of the literature are presented.

Abstract. CRH-binding protein was present in the amniotic fluid and in the umbilical cord plasma after 15 weeks and 24 weeks of pregnancy, respectively. The size of the CRH-binding protein was similar to that in the peripheral blood from normal subjects. The level of the binding of CRH-binding protein in the umbilical cord plasma during the third trimester of pregnancy was also similar to that in the peripheral blood of neonates and normal adult subjects. The binding of CRH-binding protein was temporarily decreased at 40 weeks of pregnancy. These results indicate that fetal CRH-binding protein seems to be produced at least in the second trimester of pregnancy.

Background: Umbilical cord true knot is a rare condition which affects about 1% of all pregnancies. Though the incidence is lower, it often goes undetected in antenatal period despite the availability of prenatal sonography and may lead to a compromised fetal outcome as presented in this case. In this case the presence of true knot of umbilical cord was missed despite routine sonography done just 1 week prior to delivery, when patient presented to casualty with complains of decreased fetal movements since 24 hours. This modality is said to be associated with adverse fetal outcome such as birth asphyxia or in adverse cases intra uterine fetal demise. Risk factors include long cord, polyhydramnios, small sized fetus, etc. Case Summary: 27 years old gravida two, para two, with 1 live issue with k/c/o hypothyroidism with previous lesions came with complaints of decreased fetal movement since 24 hours at 36 weeks 3 days of gestational period. The patient recorded regular ANC checkups and routine investigations within normal limits. Her USG scan done at 34.2 wks showing single loop of cord around neck and normal doppler findings. On examination her vitals were normal .Her abdominal examination showed uterus of 34 wks size, longitudinal lie, cephalic presentation and irritable with mild contractions present with scar tenderness . Her FHS were present/irregular/112 bpm with less variability. On p/v examination os was admitting tip of finger, cervix soft, 25% effaced, station high up, presenting part vertex, membrane present. She was advised admission and a cardio-tocography (CTG) was done which showed recurrent deep atypical variable decelerations with decreased beat to beat variability. An emergent cesarean section was taken. Newborn was a female diagnosed with true umbilical cord knot, 2 cm away from fetal insertion with cord length of 84 cm. The baby was shifted to NICU in view of respiratory distress. Conclusion: Despite of modern day ultrasonography and Doppler studies, true umbilical cord knot still remains a lesser diagnosed entity and so every pregnant patients should be monitored carefully with a watch for daily fetal movement count (DFMC)and weekly non stress test (NST) for fetal well being.

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.
