A fetus with absent radii in both forearms was discovered on routine ultrasound examination performed at 18 weeks of pregnancy. No other significant abnormalities were found, and no signs of haemorrhage were detected. Serial ultrasound examinations revealed no evidence of fetal internal bleeding. At 37 weeks of pregnancy, a CBC ...

In summary, NIHF is a heterogenous disorder resulting from a vast number of underlying pathologies. A thorough evaluation should be performed in all cases to attempt to establish the etiology. This requires a systematic approach that should logically proceed from least to most invasive testing. Despite increasing availability of treatment ...

A patient presented at 21 weeks gestation with nonimmune hydrops of her singleton fetus. A cordocentesis confirmed fetal anemia. During the course of the procedure, fetal cardiac arrest occurred. The fetus was resuscitated with intracardiac epinephrine and fetal transfusion was performed. The resuscitation was initially successful, however the fetus died ...

OBJECTIVE: Our purpose was to test the hypothesis that maternal anti-Kell alloimmunization produces fetal anemia by erythroid suppression. STUDY DESIGN: Erythropoiesis in 11 anemic fetuses from maternal anti-Kell alloimmunization was compared with that in 11 fetuses where the mother was alloimmunized to RhD; each was matched for hematocrit, gestational age, ...

A 36-year-old pregnant woman with anti-HPA1a antibodies underwent six fetal platelet concentrate transfusions. During the second, at 28 weeks' gestation, fetal asystole occurred in association with a post-transfusion platelet count of 813 x 10(9)/l. Asystole was reversed by an intracardiac partial exchange transfusion of normal saline for fetal blood, simultaneously ...

A published algorithm for the frequency of fetal blood sampling in the management of fetal hemolytic disease allows many pregnancies to continue 1-3 months after the last sample until delivery at term. Though the positive predictive value for antenatal anemia is known, the likelihood of either neonatal hyperbilirubinemia or an ...

Fetal cystic adenomatoid malformation, type I, is a rare pulmonary anomaly that has been diagnosed after 20 weeks' gestation. The prognosis of this malformation is usually dependent on whether it is microcystic, types II and III, or macrocystic, type I. We report a case of severe macrocystic fetal cystic adenomatoid ...

Congenital cystic adenomatoid malformation (CCAM) can be diagnosed in utero. Nonimmune hydrops associated with CCAM is a predictor of fetal demise. Fetuses with prenatally diagnosed large CCAM tumors and hydrops have undergone successful in utero resection. An animal model is needed to understand the pathophysiology of CCAM and hydrops. To ...

BACKGROUND: Diamond-Blackfan anemia is a rare form of congenital red-cell aplasia. Approximately 90% of the patients are diagnosed by 1 year of age. This report presents two pregnancies with good outcomes in a patient over a period of 1.5 years. CASE: The patient, a 20-year-old woman, was diagnosed with Diamond-Blackfan ...

During the time period 1983-90, 91,300 consecutive pregnancies were monitored for red cell alloimmunization. Once revealed, the immunizations were followed by means of repeated maternal antibody titers, maternal anti-D quantitation in D-immunized women, amniotic fluid bilirubin levels and fetal hemoglobin concentrations. High dose intravenous immunoglobulin and/or intrauterine intravascular transfusion was ...

PROBLEM: Review the current management of red blood cell alloimmunization in pregnancy. METHODS: Retrospective review of the literature and 8-year experience at Baylor College of Medicine, Houston, Tex. RESULTS: Rhesus alloimmunization continues to affect one in 1000 pregnancies. Newly diagnosed disease can be managed with serial anti-human globulin titers until ...

The term "hydrops fetalis" denotes generalized fetal edema, a condition that differs from localized edema confined to head, extremities, or body cavities. This report illustrates a case of right-sided diaphragmatic hernia associated with severe edema of the head, polyhydramnios, small hydrothorax, and ascites with an antenatal diagnosis of hydrops fetalis. ...

The etiology and pathogenesis of the HELLP syndrome, a multisystem disease occurring only in pregnancy, are still unclear. Curiously, very few authors have investigated whether inherited factors may be involved. We report two cases of HELLP syndrome in two unrelated women whose fetuses were relatives (first cousins). The first case ...

In recent years intrauterine intravascular transfusion has become the method of choice for the treatment of severe fetal erythroblastosis. Despite the association of the procedure with fetal complications such as bradycardia and overtransfusion, later neonatal neurological consequences have been only rarely reported. A case is described of a neonate who ...

45 pregnant women affected by rhesus incompatibility were treated at the Department of Prenatal Diagnosis and Therapy, Vienna, between January 1992 and March 1993. 32 patients had a cordocentesis and on 21 fetuses, anemia requiring treatment was diagnosed. A total of 71 intravascular transfusions via the umbilical vein was given. ...

Recent observations have shown that treatment with high-dose intravenous gammaglobulin (IVIgG) given to the mother may improve fetal outcome in cases of severe Rh D alloimmunization. Unfortunately, the costs of this new method of treatment are too high for routine use. Therefore, we decided to apply this treatment to the ...

Authors report the case of a newborn who died just a few hours after the birth as a result of intrauterine Parvovirus B19 infection. Diagnosis of fetal hydrops was made by ultrasound examination at the 25th week of pregnancy. Etiology was established on the basis of specific antibody findings in ...

Cystic hygroma with hydrops fetalis is considered to have grave prognosis. This report describes a case of resolution of cystic hygroma, hydrops fetalis, and fetal anemia in a female fetus with a normal karyotype. Cystic hygroma and hydrops fetalis were noted on a routine ultrasound examination at 27 weeks' gestation ...

A 32-year-old woman in her third pregnancy underwent fetal blood sampling because of a previous child with neonatal thrombocytopenia. At 33 weeks' gestation, fetal thrombocytopenia was diagnosed. Treatment was instituted antenatally with serial fetal platelet transfusions and corticosteroid therapy. Delivery was by Caesarean section at 37 weeks' gestation. Neonatal treatment ...

Forty-seven fetuses treated with intravenous intrauterine transfusion for rhesus isoimmunization were studied. At the time of first transfusion the fetuses were below average in size with the fetal femur length being directly related to the degree of fetal anemia. Subsequent to transfusion therapy there was increased growth of all fetal ...

We describe a 31-year-old patient with pure red cell aplasia of pregnancy, successfully managed with regular blood transfusions. In vitro studies showed specific inhibition of day 14 erythroid colonies (BFU-E) using serum and purified immunoglobulin G (IgG) obtained from the patient at diagnosis (before blood transfusion). The inhibition of BFU-E ...

Pyruvate kinase deficiency was diagnosed in an infant by umbilical vessel sampling at 30 weeks' gestation. Although three previous hydropic siblings had been stillborn or died in the neonatal period, this infant survived with transfusion dependent haemolytic anaemia. Prompt fetal diagnosis of pyruvate kinase deficiency is feasible and allows better ...

We report on a case of unilateral primary fetal hydrothorax leading to nonimmunological fetal hydrops (NIHF). The NIHF was treated successfully by inserting two consecutive intrauterine catheters at 23 weeks gestation. The first catheter was dislocated through the uterine wall to the maternal peritoneal cavity. At 36 weeks gestation, the ...

Fetal tumors are being diagnosed with increasing frequency and great accuracy by antenatal ultrasound. High-output cardiac failure and hydrops indicate fetal distress. Management may be limited by the gestational age of the fetus. Our experience with three fetal tumors demonstrates the dilemma with respect to timing of delivery and prognosis. ...

Platelet counts remain stable during intrauterine life (245 +/- 65 x 10(9)/litre, mean +/- SD). Before diagnosing thrombocytopenia (< 150 x 10(9)/litre), a foetal blood sample must be checked for contamination with amniotic fluid, since even slight contamination can activate coagulation and lead to a false positive result. In this ...

OBJECTIVES: This study was performed to evaluate the possible relationship between fetal spleen size and fetal hemoglobin levels and to assess the predictive value of ultrasonographically measured fetal spleen size as an estimate of the severity of fetal hemolytic anemia. STUDY DESIGN: Before 85 consecutive fetal blood samples in 28 ...

We report a case, in which direct fetal therapy by amiodarone injected into the umbilical vein during the last trimester of pregnancy was used for the treatment of fetal supraventricular tachyarrhythmia in the presence of severe hydrops fetalis. Eight injections were needed due to the recurrence of supraventricular tachycardia 1-9 ...

Neonatal hemochromatosis is a rare inherited disorder of iron metabolism in which various tissues contain excessive amounts of iron. Only in a very few cases in which the disease is associated with fetal nonimmune hydrops is there the possibility for prenatal diagnosis. We present a case of fetal nonimmune hydrops ...

The purpose of this study was to determine whether the need for late neonatal transfusion can be predicted in fetuses who received intrauterine transfusions. The records of 36 patients who underwent intrauterine transfusion were reviewed. Newborns who required late transfusions had a lower reticulocyte count at their last intrauterine transfusion, ...

We report two cases of transfusion-dependent thalassemia treated by deferoxamine during the first trimesters of two successful pregnancies. The absence of any sign(s) of toxicity or teratogenicity is remarkable; despite the data from animal models, it seems that deferoxamine in humans is rather harmless for the fetus at the usually ...

BACKGROUND: Placental chorioangiomas are the most common tumors of the placenta, occurring in 1% of all pregnancies. With the increasing use of ultrasound, prenatal recognition of these tumors is becoming more common. CASE: A 36-year-old woman presented at 28 weeks' gestation with an intrauterine mass suggested by color flow and ...

In feto-maternal alloimmune thrombocytopenia (FMAIT), severe hemorrhage, particularly intracranial haemorrhage (ICH), may occur before delivery. Management strategies to prevent ICH in high-risk pregnancies include maternal administration of intravenous Ig with or without steroids and fetal platelet transfusions. This report describes a patient who lost three fetuses with ICH because of ...

Mucopolysaccharidosis type VII (MPS VII, beta glucuronidase deficiency) has been described in association with non-immune hydrops fetalis. Three consecutive pregnancies in an itinerant family, which resulted in stillbirths caused by non-immune hydrops are described. The parents were closely related and there was a strong family history of storage disorders. The ...

A retrospective review of post-delivery antibody records was performed at a teaching hospital and a community hospital to determine the frequency of new red cell alloantibody production and transfusion during pregnancy. If alloantibody was undetected at delivery, it was assumed that alloimmunization had not occurred. When antibody was detected, a ...

OBJECTIVE: To determine the etiology, pregnancy complications, and outcome of isolated fetal pleural effusion diagnosed antenatally and to evaluate the benefits of prenatal fetal interventions. DATA SOURCES: A literature search of MEDLINE was performed for relevant English language publications between 1985-1991. In addition, reference lists of articles were used to ...

Structure and composition of stereocilia cross-links were investigated cytochemically in normal and hydropic cochleas of the guinea pig. The electron-dense markers colloidal thorium and cationized ferritin were used for visualization. Side links as well as tip links were visualized using both markers. Cationized ferritin allowed a better visualization of the ...

The intravascular volume load that an anemic fetus can tolerate was studied retrospectively in 124 consecutive intravascular transfusions in 35 erythroblastic fetuses. The tolerated volume load correlated well to the estimated fetal weight. Transfusion volume loads above 20 ml/kg of the estimated fetal weight resulted in a lower fetal survival. ...

The Winnipeg Rh Laboratory has reviewed its experiences with maternal CW alloimmunization. From September 24, 1956, to March 31, 1992, 12 women with significant CW alloimmunization underwent 18 pregnancies. In 3 (4 pregnancies) the antibody, despite its strength, was 'naturally occurring' (i.e. there was no known exposure to CW-positive red ...

In utero evolution and postnatal outcome were studied for 18 cases of congenital adenomatoid malformation (CAM) diagnosed by prenatal ultrasound. Five were macrocystic CAM, 9 were microcystic, and 4 were homogeneously hyperechogenic. Three fetuses presented with hydrops. Pulmonary amniotic shunting was performed in 3 patients. Outcome was the following: 4 ...

Fetomaternal transfusion occurs in about 50 percent pregnancies. However, it can cause severe neonatal anemia at birth. A one-day-old baby girl, small for gestational age, was born to a G1P1 woman without perinatal blood loss or obstetric complication. Pallor and mild tachypnea were noted after birth. Laboratory examination revealed severe ...

As there is only little information on pregnancy complicated by hereditary spherocytosis, we report on 8 patients with this disorder who had a total of 19 pregnancies. 10 pregnancies occurred in patients before splenectomy, and 9 occurred after splenectomy. There were 13 term births, 4 spontaneous abortions and 2 therapeutic ...

OBJECTIVE: To report the first four years' clinical experience with fetal intravascular blood transfusion for the treatment of fetal haemolytic anaemia in Western Australia. SETTING: King Edward Memorial Hospital, Perth, which is the sole tertiary level perinatal centre in Western Australia with a referral base of approximately 25,000 pregnancies each ...

Intravascular fetal transfusions are occasionally complicated by extravascular deposition of transfused blood or by fetal bradycardia on penetration of the needle into the umbilical cord. It is desirable therefore to continuously monitor the intravascular location of the needle and the fetal heart rate. This can be achieved by Doppler velocimetry ...

Neonatal alloimmune thrombocytopenia (NAIT), which usually involves sensitization to P1A1 (HPA-1a), may have devastating complications for the fetus. These may be prevented by antenatal treatment of severe cases with either maternally administered high-dose gamma-globulin and/or repeated intrauterine platelet transfusions. Determination of the paternal platelet phenotype is useful for counseling parents ...

We report on fetal hydrops presenting at 18 weeks of gestation and diagnosed as beta-glucuronidase deficiency. The parents were first cousins and there were 2 previous similar fetal deaths. beta-Glucuronidase was absent in cultured fetal fibroblasts and lymphoblasts but was normal in the tested relatives. The activities of other lysosomal ...

This article has presented an overview of developments in the treatment of HDN. The number of cases requiring treatment that have occurred in the last decade has dropped because of the development and implementation of Rh immunoprophylaxis, although this treatment still appears to be underutilized in the United States. Failure ...

OBJECTIVE: To review our experience with, and to evaluate the efficacy of, antenatal pharmacologic treatment of pregnancies complicated by alloimmune thrombocytopenia. METHODS: We reviewed the records of six pregnancies complicated by alloimmune thrombocytopenia recently cared for at the University of Iowa Fetal Diagnosis and Treatment Unit. All patients had a ...

The first fetal transfusion was performed at the National Women's Hospital in Auckland in 1963. From that time until the end of 1990, a total of 1041 transfusions have been completed on 459 fetuses. The survival rate for affected pregnancies rose significantly from 39% in 1963-65 to 90% in 1986-90. ...

The acardiac fetus is a rare entity found only in monozygotic multiple pregnancy. Although the acardiac fetus is non-viable, the perinatal mortality rate for the normal fetus may be as high as 50 per cent, and is usually associated with fetal heart failure and hydrops fetalis, or as the result ...

By chance, we had the opportunity to make serial sonographic observations of the extrusion of meconium in a case of meconium peritonitis. Inflammation leads to exudative processes and production of fluid (ascites) in the fetal abdomen. Sonography at that stage of the disease may lead to a misdiagnosis such as ...
