This article reviews the actual knowledge and future developments of ultrasound techniques for the evaluation of fetal growth and well-being. Sonography allows the visualization of the fetus in utero and is utilized worldwide for the evaluation of fetal growth and well-being. Fetal biometry assessment is performed in the second half of pregnancy when deviations of fetal growth can be best recognized through alterations of fetal abdominal circumference growth. Doppler velocimetry of utero-placental vessels identifies alterations of placental perfusion and is valuable in the assessment of fetal brain, heart, and liver perfusion, thus being utilized in the timing of delivery. Recently, three-dimensional ultrasound evaluation of fetal organs and placenta is being developed. 相似文献

The severe risk situations characterized by fetal growth retardation are outlined. The small fetus, whether growth retarded or severely premature, is best delivered where both fetal monitoring and newborn resuscitation are available. The moderate risk fetus can be monitored at home base with clinical skills described in this article. 相似文献

As prenatal diagnosis has become increasingly sophisticated and as technological advances have enhanced the range of diagnostic capabilities, invasive therapies have developed from our expanded understanding of the natural history and pathophysiology of structural anomalies. This article presents a comprehensive review of the treatment options currently available for the entire spectrum of fetal diagnoses that are potentially surgically correctable. The current indications, contraindications, and outcomes for shunting procedures, open fetal surgery, and fetoscopic surgeries are reviewed. 相似文献

Presently, MRI is an adjunct to prenatal sonography. It provides information that can aid in the diagnosis of fetal anomalies, affect prenatal counseling and management of the pregnancy, and guide prenatal intervention and delivery planning. With further advances in technology, particularly shorter scan times and better image resolution, the applications for fetal imaging are likely to increase. 相似文献

The purpose of our retrospective observational series was to determine whether the sonographic characteristics of fetal megacystic bladders can be used to reliably establish the most likely diagnosis in fetuses with this condition. The sonographic records of pregnant patients referred to our institutions over a 10‐year period who were found on initial 2‐dimensional sonography to be carrying fetuses with megacystis were examined for evidence of a keyhole sign, bladder thickness, amniotic fluid index, and fetal sex. When available, 3‐/4‐dimensional sonography, Doppler angiography, tomographic ultrasound imaging, virtual organ computer‐aided analysis, and automatic volume calculation were used as part of the detailed fetal anatomic survey. Twenty fetuses with megacystis were identified. Seventeen were male; 2 were female; and 1 had ambiguous genitalia. All male fetuses with megacystis originally had a diagnosis of prune belly syndrome. The diagnosis for 10 male fetuses with a keyhole sign was changed to megacystis secondary to posterior urethral valves. The fetus with ambiguous genitalia had prune belly syndrome. One of the female fetuses had a diagnosis of urethral atresia, and the diagnosis for the other female fetus was megacystis‐microcolon‐intestinal hypoperistalsis syndrome. In conclusion, in fetuses with megacystic bladders, it is possible to distinguish between cases with prune belly syndrome, posterior urethral valves, urethral atresia, and megacystis‐microcolon‐intestinal hypoperistalsis syndrome by a detailed anatomic survey using 2‐ and 3‐/4‐dimensioinal sonographic techniques. 相似文献

Fetal electrocardiography is a simple, rapidly performed procedure for determining fetal viability and multiple pregnancy. It is safe for both mother and fetus and can be regularly repeated. Diagnostic accuracy of the technic correlates with the period of gestation. In the series of patients reported in this paper, the percentage of correct diagnoses, confirmed by delivery, was 95.25. 相似文献

Records of 24 pregnancies with fetal polydactyly were reviewed for the type of polydactyly, family history, associated sonographic findings, genetic testing, and postnatal/postmortem examination findings. The importance of fetal polydactyly can be mainly elucidated by the family history and absent or associated anomalies on a specialized malformation scan. Fetal karyotyping diagnoses frequent chromosomal anomalies in about half of cases with additional malformations, and array comparative genomic hybridization may be a future means of detecting cryptic chromosomal aberrations. Syndromic disorders of monogenic origin demand a careful interdisciplinary clinical assessment for establishing a clinical diagnosis and prognosis for the outcome of the child. 相似文献

Given that practice variation exists in the frequency and performance of ultrasound and magnetic resonance imaging (MRI) in pregnancy, the Eunice Kennedy Shriver National Institute of Child Health and Human Development hosted a workshop to address indications for ultrasound and MRI in pregnancy, to discuss when and how often these studies should be performed, to consider recommendations for optimizing yield and cost effectiveness, and to identify research opportunities. This article is the executive summary of the workshop. 相似文献
