Dandy-Walker malformation is a rare abnormality of the central nervous system (CNS) with a reported incidence of 1 in 25,00-35,00 live births and a slight female predominance. It accounts for 1-4% of cases of antenatally detected hydrocephalus. Dandy Walker variant forms part of the spectrum of Dandy Walker malformation. It ...

Vasa praevia is an uncommon obstetric complication, which if undiagnosed is associated with a high fetal mortality because of the rapid haemorrhage from tearing of fetal vessels resulting in fetal exsanguinations. Antenatal diagnosis in most cases is not made and therefore prevention of fetal death is not possible. Outcome depends ...

BACKGROUND AND OBJECTIVES: The exact antenatal prevalence of congenital anomalies in Saudi society is unknown. Early antenatal diagnosis of congenital anomalies is crucial for early counselling, intervention and possible fetal therapy. The objective of this study was to evaluate the antenatal frequency of major congenital anomalies and malformation patterns in ...

This case study describes a pregnant patient with vaginal bleeding who had a bedside endovaginal ultrasound in the emergency department (ED). The emergency physician identified a live intra-uterine pregnancy (IUP) with another structure that appeared to be a second gestational sac. The patient subsequently had an endovaginal ultrasound in the ...

OBJECTIVES: Defecation proctography is the standard method used in the investigation of obstructed defecation. Translabial ultrasound has recently been shown to demonstrate rectocele, enterocele and rectal intussusception. We performed a comparative clinical study to determine agreement between the two methods. METHODS: Thirty-seven women scheduled to undergo defecation proctography for obstructed ...

During the last few decades, the use of ultrasonography for the detection of fetal abnormalities has become widespread in many industrialised countries. This resulted in a shift in timing of the diagnosis of congenital abnormalities in infants from the neonatal period to the prenatal period. This has major implications for ...

The understanding of early pregnancy both normal and abnormal as seen by transvaginal ultrasound is an essential skill of any clinician involved in reproductive medicine and infertility. The "sonomicroscopy" of the vaginal probe results from the high level of magnification and close proximity to the structure being studied. In addition, ...

Our objective was to determine whether the rate of small for gestational age (SGA) infants and adverse perinatal outcome are increased in pregnancies diagnosed with an isolated single umbilical artery (SUA). We compared 297 pregnancies with a SUA diagnosed on routine obstetrical ultrasound with 297 pregnancies with a three-vessel cord ...

Processes that can produce a biological effect with some degree of heating (ie, about 1 degrees C above the physiologic temperature) act via a thermal mechanism. Investigations with laboratory animals have documented that pulsed ultrasound can produce elevations of temperature and damage in biological tissues in vivo, particularly in the ...

Policies for routine third trimester obstetrical ultrasound examinations differ among countries. In Canada, a routine third trimester ultrasound scan is not offered in the low-risk pregnancy population. This practice is based mainly on results of a meta-analysis published in 2001 that concluded "routine late pregnancy ultrasound in low-risk or unselected ...

Agenesis of the corpus callosum is found in about 5 per 1,000 births and it is due to maldevelopment or, secondary, to destructive lesions. Multicystic dysplastic kidneys is a consequence of either developmental failure of the mesonephric blastema to form nephrons or to early urinary obstruction due to urethral or ...

OBJECTIVE: The Ritscher-Schinzel syndrome (RSS), also known as the 3C syndrome, is an autosomal recessive disorder classically comprising craniofacial, cerebellar and cardiac defects. The underlying molecular etiology remains unknown; therefore, prenatal diagnosis of recurrences depends on identification of the associated structural anomalies on second trimester ultrasound examination. Identification of recurrences ...

Intracranial teratoma, although a rare disease, is nonetheless the most common of the congenital tumors of the central nervous system in the neonatal period. It can be diagnosed antenatally by ultrasound. The prognosis for fetal forms of teratoma is very grim. We report here the case of an immature teratoma ...

Diagnostic ultrasound is used selectively in late pregnancy where there are specific clinical indications. However, the value of routine late pregnancy ultrasound screening in unselected populations is controversial. The rationale for such screening would be the detection of clinical conditions which place the fetus or mother at high risk, which ...

Fetal seizures are an unusual phenomenon. When diagnosed by ultrasonography, they are frequently associated with malformations and carry a poor prognosis. We describe first trimester seizures in two siblings with arthrogryposis multiplex congenita. In both cases, convulsions appeared before other sonographic signs of the disease. Review of the literature revealed ...

Ultrasound screening of structural fetal malformations is mainly based on the use of ultrasounds during the second trimester of pregnancy. The diagnostic sensibility of ultrasounds varies in the different multicentric studies reported in literature and is correlated to different factors: gestation period, type of malformation, number of ultrasounds performed, operator ...

Effect of ultrasound sonication was examined on the electroplating of iridium in aqueous hexabromoiridate(III) solution. The electrodeposits were evaluated by observing the defects of the iridium deposits by means of voltammetry, in which the current-potential curves of the iridium deposits on copper were measured. Applying ultrasound sonication to the electroplating ...

There are three primary methods of gestational age estimation: dating based on last menstrual period (LMP), ultrasound-based dating and neonatal estimates. We review the strengths and limitations of each method as well as their implications for research. Dating based on LMP is a simple, low-cost method of estimating gestational age. ...
Dietz Patricia M - - 2007
Although early ultrasound (<20 weeks' gestation) systematically underestimates the gestational age of smaller fetuses by approximately 1-2 days, this bias is relatively small compared with the large error introduced by last menstrual period (LMP) estimates of gestation, as evidenced by the number of implausible birthweight-for-gestational age. To characterise this misclassification, ...

Tuberous sclerosis complex (TSC) is an autosomal-dominant neurocutaneous disorder with multi-organ involvement. The diagnosis is suspected at fetal ultrasound on the discovery of multiple cardiac rhabdomyomas (CRs). They typically develop in utero and undergo spontaneous regression during the first years of live. With developing neuroradiological methods more light is shed ...

We conducted a pilot study on 60 women in the second stage of labour using trans-abdominal ultrasound to assess fetal position prior to obstetric intervention. Digital examination failed to assess the correct fetal position in 16 (26%) of the cases. Ultrasound helped in determining fetal position in 57 (95%) of ...

OBJECTIVE: The ability to predict surgically relevant fetal renal pyelectasis is limited. We sought to determine whether the intrauterine timing of prenatal pyelectasis can predict the need for postnatal surgery. METHODS: We retrospectively reviewed all patients with ultrasound measurements of the fetal renal pelvis during the 2nd and 3rd trimesters ...

PURPOSE: As a form of energy, diagnostic ultrasound has bioeffects on living tissues. The thermal index (TI), TIS (TI for soft tissue), TIB (TI for bone), TIC (TI for cranial bone) expresses the potential for rise in temperature at the ultrasound beam's focal point. The mechanical index (MI) indicates the ...

Ultrasound has been used to aid cannulation of veins of the neck, chest, antecubital fossa, and femoral vein. This investigation compared the traditional method of peripheral intravenous (IV) cannulation of veins of the hands and forearms with ultrasound-guided IV cannulation of these veins. After obtaining institutional review board approval and ...

Three-dimensional (3D) ultrasound of the fetal heart is increasingly being used in prenatal diagnosis. While very detailed fetal cardiac studies can be performed using the various 3D ultrasound modalities, their utility for screening for fetal heart disease is yet to be proven. With the emergence of even newer technologies such ...
