BACKGROUND: Early fetal echocardiography (FE), performed at 12 to 16 weeks' gestational age (GA), can be used to screen for fetal heart disease akin to that routinely performed in the second trimester. The efficacy of FE at earlier GAs has not been as well explored, particularly with recent advances in ultrasound technology. The aim of this study was to evaluate the efficacy of early FE in assessing fetal heart structure, and the added benefit of color Doppler (CD), from as early as 6 weeks through to 13(+6) weeks' GA...

OBJECTIVES: To determine whether color Doppler sonography increases the detection of pregnancies at risk for adverse outcomes. METHODS: Participants admitted to labor and delivery with the anticipation of a vaginal delivery underwent measurements of amniotic fluid volume (AFV) using amniotic fluid index (AFI) and single deepest pocket (SDP) techniques by grayscale followed by color Doppler sonography. Oligohydramnios was defined as an AFI of less than 5 cm or an SDP of less than 2 cm...

Tubal choriocarcinoma is uncommon, and its magnetic resonance imaging characteristics have not yet been reported. In this report, a 39-year-old woman presented with irregular painless vaginal bleeding and a palpable left lower abdominal lump for 2 months following 6 weeks' amenorrhea and positive urine pregnancy test. Her serum β-human chorionic gonadotropin value was significantly increased. Ultrasound revealed a left adnexal mass, which showed no blood flow signal on Color doppler flow imaging. A further MR examination showed a well-defined cystic-solid mass with cystic component accounting for a large proportion in the left lower abdomen...

Umbilical cord entanglement is the leading cause of fetal mortality in monoamniotic twin pregnancies and a pseudo monoamniotic environment. Published methods for detecting this complication include color Doppler and pulsed Doppler sonography; however, no method provides an absolute diagnosis. In this case, we report the diagnosis of umbilical cord entanglement using dual-gate Doppler imaging. A 35-year-old woman was referred to our hospital at 28 weeks of gestation for prenatal management because of diagnosis of a monochorionic diamniotic twin pregnancy with spontaneous septostomy of the dividing membranes...

Postpartum hemorrhage (PPH), a leading cause of maternal mortality, can occur within 24 h of delivery (primary PPH), or during the period from 24 h after delivery to Week 6 of puerperium (secondary PPH). It requires health professionals to be alert to the symptoms to ensure prompt diagnosis and treatment, especially in the case of rupture of a uterine artery pseudoaneurysm (UAP) due to its life-threatening consequence (Baba et al., 2014). Most of the published case reports or case serials describe UAP as a possible cause of delayed PPH after traumatic procedures during delivery or pregnancy termination, including cesarean section (CS), manual removal of the placenta, or dilation and curettage (D&C) (Wald, 2003)...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome (TTTS) recipient's vascular architecture remains unknown. OBJECTIVES: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were: 1) to establish a 3D color Doppler ultrasound method of measuring umbilical arterial (UA) length relative to its corresponding venous segment in the Umbilical cord using AV-angle, 2) to compare recipient AV-angle to gestational age-matched controls, and 3) to test the association of AV-angle with recipient heart failure...

Conjoined twins are a rare, but serious, complication of monozygotic twins. Early prenatal diagnosis of conjoined twins is increasingly made with transvaginal ultrasound and color Doppler studies. Most prenatally diagnosed conjoined twins are terminated due to the high perinatal mortality, but advancement in pediatric surgery has allowed for successful postnatal separation in a small number of cases, and some parents may consider this option over termination of pregnancy. It is important to get a detailed prenatal ultrasound for the site and extent of fusion for an accurate categorization...

We sought to describe the prenatal features and postnatal outcomes of the "criss-cross heart" (CCH) with crossing atrioventricular connections as encountered in 5 cases and to review the literature regarding fetal diagnoses of this lesion. We reviewed the clinical history and fetal echocardiograms of 5 patients with a diagnosis of CCH encountered in our institution from 2010 to 2015. Affected pregnancies were identified through the University of Alberta fetal cardiology database. Fetal and postnatal echocardiograms, prenatal and postnatal clinical records, autopsy, and surgical reports were reviewed...

Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

A 27-year-old primiparous woman with 28 weeks gestational age was admitted to our hospital with worsening shortness of breath. She was diagnosed with Ebstein's anomaly three years ago, but preferred to be left untreated. The patient was not cyanotic and her vital signs were stable. Her ECG showed incomplete RBBB and prolonged PR-interval. Blood tests revealed mild anemia. Observation of two-dimensional echo with color flow Doppler study showed Ebstein's anomaly with PFO as additional defects, EF of 57%, LV and LA dilatation, RV atrialization, severe TR, and moderate PH with RVSP of 44...

Paraovarian cysts are a rare pathology, constituting 10-20% of the adnexal masses. The origin can be represented by paramesonephric ducts (Hydatid cysts of Morgagni), vestiges of mesonephric ducts also represented by mesothelium, or neoplastic (cystadenomas or cystadenofibromas) that are mostly benign. Borderline or malignant paraovarian tumors are encountered less often. This article presents a case of paraovarian cyst in a 37-year-old patient, with a history of 2 pregnancies, completed by cesarean. The patient sought medical attention for an asymptomatic voluminous ovarian cyst, detected in a routine ultrasound scan...

Caesarean scar pregnancy is one of the rarest forms of ectopic pregnancy. Transvaginal ultrasound and color flow Doppler provides a high diagnostic accuracy. A delay in diagnosis and treatment can lead to uterine rupture, major hemorrhage, hysterectomy and serious maternal morbidity and mortality. Early diagnosis can offer treatment options of avoiding uterine rupture and hemorrhage, thus preserving the uterus and future fertility. Primary health care provider should know about this rare entity, because if diagnosed timely, and referral to specialized centre is done without delay will definitely save maternal morbidity and mortality...

REVIEW
Dawn S Hughes, Everett F Magann
The evaluation of amniotic fluid volume (AFV) is an established part of the antenatal surveillance of pregnancies at risk for an adverse pregnancy outcome. The two most commonly used ultrasound techniques to estimate AFV are the amniotic fluid index (AFI) and the single deepest pocket (SDP). Four studies have defined normal AFVs, and although their normal volumes have similarities, there are also differences primarily due to the statistical methodology used in each study. Dye-determined AFV correlates with ultrasound estimates for normal fluid volumes but correlates poorly for oligohydramnios and polyhydramnios...
