Diaphragmatic eventration is the upward displacement of the abdominal viscera secondary to a thin or paralytic diaphragm. Its clinical presentations and radiographic pictures are similar to those of diaphragmatic hernia. Prenatal diagnosis of diaphragmatic eventration is extremely rare. A pregnant woman was referred to us because of abnormal cardiac findings noted at 20 weeks of gestation. A diagnosis of partial anomalous pulmonary venous connection was made on the basis of our findings of right atrial enlargement with an abnormal vascular channel drainage to it. The infant was born via cesarean section at 40 weeks and developed complications of cyanosis immediately after birth. Postnatal imaging studies and surgical findings disclosed right side diaphragmatic eventration with liver and associated vasculature upward displacement into the right pleural cavity. The cardiac structure was otherwise normal. We conclude that when an abnormal vessel tracing and unexplainable cardiac chamber asymmetry is encountered, diaphragmatic eventration should be considered as one of the differential diagnoses. Correct recognition and transferral to the hospital for neonatal assistance may lead to timely and appropriate management of these fetuses. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Early amniocentesis at less than 14 weeks gestation is becoming more common in prenatal diagnosis populations. Randomized studies are minimal and have not had the power to determine the accuracy and safety of the procedure compared to chorionic villus sampling or mid-trimester amniocentesis. Procedures at 11+0-12+6 weeks should be considered experimental. This clinical review considers the ethics, embryology, and clinical experience (cytogenetics, AFP, AChE, procedure and cytogenetic failures, spontaneous and therapeutic pregnancy losses, congenital anomalies) of early amniocentesis. 相似文献

Although congenital mesoblastic nephroma (CMN) is a rare benign congenital renal tumor, it is the most common solid renal tumor in the newborn period. The most common presentation of congenital mesoblastic nephroma is polyhydramnios, and only one case with prenatal fetal hydrops has been previously reported. Prenatal diagnosis of CMN has previously been made on the basis of the findings of sonography in the third trimester, and magnetic resonance imaging (MRI)–based diagnosis has been reported recently. Here we report a case of prenatally diagnosed classical type CMN diagnosed at 22 + 3 weeks of gestation based on the findings of sonography and magnetic resonance imaging. The characteristic imaging findings in this case were fetal hydrops and polyhydramnios. To our knowledge, this is the youngest reported gestational age for prenatal diagnosis of CMN and it is the second case of CMN associated with fetal hydrops detected prenatally.

Prevalence of congenital heart disease increases with nuchal translucency (NT) thickness. First-trimester fetal bradycardia may result from heart block associated with complex congenital heart disease. We report two cases detected in the first trimester of pregnancy, in which both fetuses showed an increased nuchal translucency and bradycardia. Fetal karyotype was normal in both fetuses. First-trimester fetal echocardiography was performed and, in both cases, complex congenital heart disease was diagnosed. We discuss the added role of fetal heart rate in first-trimester ultrasound screening, in fetuses with increased nuchal translucency and normal karyotype. We stress, as well, the importance of echocardiography performed in the first trimester as a potential tool for early diagnosis in selected cases. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Cervical teratoma is a neoplasm composed of embryonic tissues with representation of all three germ layers. We report an extremely rare case of fetal cervical teratoma presenting at 24 weeks of gestation. A submaxillary mass and agenesis of corpus callosum were identified on ultrasonography, associated with agenesis of corpus callosum and a subarachnoid cyst.

Open fetal surgery through a wide hysterotomy is no longer a real option for prenatal intervention, but a minimally invasive approach has emerged as treatment for a small number of indications. Endoscopic ablation of placental vessels is the preferred treatment for severe twin-to-twin transfusion syndrome and it may be the only chance to salvage the most severe forms of congenital diaphragmatic hernia. Several other indications are currently under review and may become justified in the future, provided that diagnostic accuracy and patient selection become more accurate. Before invasive fetal intervention becomes widely accepted, however, we need to better define outcome. It is no longer acceptable to express results in terms of survival at birth. Survival at discharge and long-term morbidity must be considered as well. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Progress in prenatal diagnosis can lead to the diagnosis of severe fetal abnormalities for which natural history anticipates a fatal outcome or the development of severe disability despite optimal postnatal care. Intrauterine therapy can be offered in these selected cases. Prenatal diagnosis is the only field of medicine in which termination is an option in the management of severe diseases. Fetal therapy has therefore developed as an alternative to fatalist expectant prenatal management as well as to termination of pregnancy (TOP). There are few standards of fetal care that have gone beyond the stage of equipoise and even fewer have been established based on appropriate studies comparing pre- and postnatal care. Several ethical questions are being raised as fetal surgery develops, including basic Hippocratic principles of patients' autonomy and doctors' duty of competence moving the boundaries between experimental surgery, therapeutic innovation and standard care. In addition, the technical success of a fetal intervention can only rarely fully predict the postnatal outcome. Managing uncertainty regarding long-term morbidity and the possibility for fetal therapy to change the risk of perinatal death into that of severe handicap remains a critical factor affecting women's choice for TOP as an alternative to fetal therapy.
