1/69. Severe nonimmune hydrops fetalis and congenital corneal opacification secondary to human parvovirus B19 infection. A case report.BACKGROUND: In parvovirus infections in animals, congenital anomalies are seen, but the teratogenic potential in humans seems fairly low. CASE: A fetus with hydrops, ascites and pleural effusion was seen at a prenatal ultrasound examination. Fetal cordocentesis was performed, and fetal blood was positive for parvovirus antibodies. Intravascular fetal blood transfusion was given at 21 and 23 weeks of gestation. At 39 weeks labor started spontaneously, and a 2,960-g, female infant was delivered. The newborn had bilateral opacification of the cornea. CONCLUSION: In this case a combination of fetal parvovirus B19 infection and congenital corneal opacification was seen. This case also demonstrates that blood transfusions in hydropic fetuses may reverse the hydrops and prevent intrauterine death.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
2/69. Fetal trisomy 10 mosaicism: ultrasound, cytogenetic and morphologic findings in early pregnancy.We report the ultrasound, cytogenetic and morphologic findings in a case of trisomy 10 mosaicism prenatally detected by chorionic villus sampling (CVS). CVS sampling was carried out at the 13th week of gestation because of ultrasound diagnosis of hydrops fetalis and hygroma colli. trisomy 10 mosaicism was diagnosed in cells from the cytotrophoblast (short-term culture) and the chorionic villus core (long-term culture). Fetal mosaicism was confirmed after termination of pregnancy in umbilical cord cells, placenta and fetal skin fibroblasts.- - - - - - - - - - ranking = 1059.1972201346keywords = umbilical cord, umbilical, cord (Clic here for more details about this article) |
3/69. A case of large placental chorioangioma with non-immunological hydrops fetalis.A 34-year-old Japanese woman (gravida 2, para 2) with polyhydramnios and non-immunological hydrops fetalis was referred to our department at 32 weeks of gestation. On admission, the blood pressure was 120/60 mmHg and there was no pitting edema of the lower extremities. An ultrasound examination disclosed a large placental tumor 5.8 cm x 4.4 cm x 4.8 cm. Fetal lung compression was suspected because the lung-thorax transverse area ratio was 0.13. The preload index of the inferior vena cava was 0.74, suggesting fetal cardiac failure. After fetal pleural effusion was aspirated, lung compression developed. cordocentesis was performed at 33 weeks of gestation, and the fetal karyotype was confirmed to be 46, XY from an umbilical blood cultivation. The patient underwent a cesarean section at 33 weeks of gestation due to severe uterine contraction after preterm PROM. The baby was a 3,840 g male with a distended abdomen. apgar score at 1 minute was 1. A chest X-ray demonstrated respiratory distress syndrome. The baby was discharged on the 69th day after birth and he is now 2 years and 9 months old and healthy.- - - - - - - - - - ranking = 355.23467388651keywords = umbilical (Clic here for more details about this article) |
4/69. Successful treatment of refractory supraventricular tachycardia by repeat intravascular injection of amiodarone in a fetus with hydrops.We report the case of a fetus with supraventricular tachycardia complicated by congestive heart failure and ascites. After failure of initial transplacental treatment, the injection of amiodarone into the umbilical vein combined with evacuation of ascites achieved conversion to sinus rhythm and restored cardiac function thus allowing pregnancy to go to term. This report suggests that direct fetal therapy by umbilical vein puncture and evacuation of effusions constitutes an effective treatment for supraventricular tachycardias with massive fetal hydrops which do not respond to transplacental treatment.- - - - - - - - - - ranking = 710.46934777302keywords = umbilical (Clic here for more details about this article) |
5/69. Rapid determination of zygosity and common aneuploidies from amniotic fluid cells using quantitative fluorescent polymerase chain reaction following genetic amniocentesis in multiple pregnancies.Following second-trimester twin amniocentesis, we used quantitative fluorescent polymerase chain reaction (QF-PCR) assays and polymorphic small tandem repeats (STR) for rapid determination of zygosity and common aneuploidies from amniotic fluid (AF) cells in four pregnancies with like-sex twins, fused placentae and inconclusive chorionicity. The first and the second cases were suspected to have inadvertent sampling of the same amniotic cavity twice. The first case showed a dizygotic (DZ) pattern and repeat amniocentesis was thus avoided. The second case was monozygotic (MZ) and was complicated by discordant fetal growth and twin-twin transfusion syndrome. The third case was associated with a co-twin malformation, occipital encephalocele. dna studies revealed MZ twinning with a discordant structural defect. The fourth case was associated with co-twin abnormalities of cystic hygroma and hydrops fetalis. dna studies showed DZ twinning with discordant structural and chromosomal defects. The QF-PCR assay with STR has the advantages of rapid determination of zygosity and common aneuploidies in AF cells. This simple test appears to be useful in the instances of possible inadvertent puncture of the same amniotic cavity twice during amniocentesis and of discordant fetal structural and/or chromosomal abnormalities following genetic amniocentesis in multiple pregnancies with uncertain chorionicity.- - - - - - - - - - ranking = 4keywords = cord (Clic here for more details about this article) |
6/69. In utero development of hypertensive necrotizing pulmonary arterial lesions: report of a case associated with premature closure of the ductus arteriosus and pulmonary hypoplasia.Premature closure of the ductus arteriosus (PCDA) is an uncommon defect in which pulmonary hypertension (PH) has been documented by echocardiography in patients and by direct measurement after experimental PCDA in animals. The pulmonary vascular histology in human cases has received little attention but in the few recorded observations the vessels were either normal or showed increased muscularity. We report the case of a 31 week hydropic female stillborn monozygotic twin in whom postmortem examination disclosed PCDA and hypoplasia of the lungs. Atypical plexiform lesions with necrotizing pulmonary arteritis were present. These lesions represent vascular consequences of severe pulmonary hypertension produced by greatly enhanced blood flow through a restricted vascular bed resulting from the combined effects of these two abnormalities. The findings in this case of PCDA with presumed severe PH indicate that severe pulmonary vascular changes can develop in utero and that the interval of time needed for development of such chances in secondary PH is relatively short.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
7/69. Agenesis of the ductus venosus and its correlation to hydrops fetalis.Absence of the ductus venosus is a rare vascular anomaly. We report a late onset of a hydrops fetalis seen in a fetus at 34 completed weeks of gestation. A persistence of the cranial parts of the left and right umbilical veins and of the paired cranial vitelline veins with an absent ductus venosus led to a bilateral hydrothorax, ascites and skin-edema. Postnatally the hydrops resolved within 7 days most probably due to the change from the fetal to the adult circulation. The abnormal venous system was confirmed by angiography. Agenesis of the ductus venosus can manifest in two different morphologic patterns: The umbilical vein drains exclusively into the left branch of the intrahepatic portal vein or the umbilical vein drains into the inferior vena cava or directly into the right atrium by-passing the liver completely. In both patterns, the preferential direction of the flow towards the foramen ovale is not present. While the first pattern leads to hyperperfusion of the liver parenchyma, the latter would result in reduced perfusion and oxygenation. Our findings suggest that agenesis of ductus venosus might induce hydrops fetalis. We conclude, that in every case of hydrops fetalis the venous system should be evaluated by ultrasonography prenatally and/or immediately postnatally.- - - - - - - - - - ranking = 1065.7040216595keywords = umbilical (Clic here for more details about this article) |
8/69. Early prenatal management of a fetal ventricular tachycardia treated in utero by amiodarone with long term follow-up.Fetal cardiac arrhythmias are one of the causes of intra-uterine congestive heart failure and non-immune hydrops fetalis leading to fetal death. As ventricular tachycardia (VT) is rarely diagnosed in utero, it leads to emergency deliveries. We report a prenatal diagnosis of fetal tachycardia at 20 weeks of gestation associated with non-immune hydrops fetalis. The tachycardia seemed to be supraventricular and was initially treated by digoxin and sotalol. The hydrops increased and sotalol was stopped in order to give the mother a high dose of amiodarone by mouth over a long period. Although the tachycardia, which the ECG recorded at birth revealed to be of ventricular origin, persisted but at a lower rate, the new treatment proved successful. The child is three years old now and health, though with persistent VT. In conclusion, fetal tachycardia with similar ventricular and atrial rates can be a VT and the drug of choice in this case seems to be amiodarone.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
9/69. Angio-oedema in a neonate with IgG antibodies to parvovirus B19 following intrauterine parvovirus B19 infection.We report a neonate with angio-oedema following fetal hydrops caused by maternal parvovirus B19 infection. Levels of complement components, including total haemolytic complement activity and C1 inhibitor concentration, were within normal ranges in cord blood. Neonatal angio-oedema might be included in the clinical spectrum of parvovirus B19 infection in pregnancy.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
10/69. Reversal of foetal hydrops and foetal tachyarrhythmia associated with maternal diabetic coma.Foetal hydrops is always a challenge for the clinician. We report a case of tachycardia associated with hydrops and hydramnios in a pregnancy complicated with diabetic coma at 28 weeks gestation. Normal foetal heart rate was recorded immediately after correction of maternal acidotic status and hydrops eventually disappeared. The woman was delivered at 32 weeks and the baby had an uncomplicated postnatal course. We hypothesise that maternal ketoacidosis has been the precipitating factor of tachycardia and congestive heart failure and that this case is conceptually similar to the "late death" phenomenon, reported in cases of poorly controlled maternal diabetes.- - - - - - - - - - ranking = 1keywords = cord (Clic here for more details about this article) |
