We report the case of a massive fetal cardiac rhabdomyoma recently occurred at our clinic. A woman at 23 weeks of gestational age was referred to our center for a fetal cardiac echogenic mass of 26 mm detected at the second-trimester screening ultrasound. During pregnancy, though, the mass progressively increased its dimensions until reaching 48 mm in diameter at 37 weeks of gestation. Fetal echoencephalography and brain magnetic resonance did not show any further fetal anomalies, but molecular genetic testing at amniocentesis revealed a heterozygotic missense variant of gene TSC2 associated with Tuberous Sclerosis. The mass was therefore most likely preferable to a single large rhabdomyoma of gradually increasing dimensions. The baby was delivered at term with a cesarean section. Because of the rhabdomyoma remarkable size and newborn ECG electrical alterations, postnatal therapies with Flecainide and Everolimus were started. Everolimus treatment led to a significant and progressive reduction in the cardiac mass volume. This case, therefore, shows the efficacy of what seems to be a promising treatment in pediatric patients with large rhabdomyomas. Rhabdomyomas may present with different features: most often they appear as multiple masses along the interventricular sept, but they may also appear as a single large thoracic mass. When a rhabdomyoma is suspected, genetic counseling is recommended. Both before and after birth, a multidisciplinary approach is useful to choose the appropriate therapy for the newborn. mTOR inhibitors therapies look like promising therapeutic approaches to stimulate the involution of rhabdomyomas.

Objective: Evaluate two new 3D and two new 2D ultrasound formulae for fetal weight estimation against the modified Hadlock formula and compare their estimation to the actual fetal weight.Methods: Fifty pregnant females were included.Inclusion Criteria: singleton pregnancy, within five days of delivery and normal or IUGR pregnancy. 3D evaluation of the fetal thigh and arm was done to calculate mid-thigh and mid-arm volumes. The actual fetal weight was recorded at delivery and compared to the estimated weights.Results: Modified Hadlock formula had higher accuracy, whereas fractional limb volume method had higher precision. Systematic errors for the modified Hadlock formula, Model 6 of fractional limb volume and the original mid-thigh soft tissue thickness methods were 2.3%, -4.8% and 11%, respectively, whereas the random errors were 7.7%, 6.2% and 13.8%, respectively. The percentage of cases estimated within 5%, 10% and 15% of actual fetal weight were 48%, 86% and 92%, respectively, for the modified Hadlock method, whereas for the fractional limb volume method, these were 40%, 78% and 98%, respectively.Conclusion: Fractional limb volume method is a very promising method for fetal weight estimation. Its performance is not significantly different from the modified Hadlock method. [ABSTRACT FROM AUTHOR]

Ultrasound imaging is an essential component of healthcare services. This study sought to explore perceptions of access, and factors which shape access, to ultrasound imaging in two northern, remote, Indigenous communities in Canada. Using interpretive description as a methodological approach and a multi-dimensional conceptualisation of access to care as a theoretical framework, 15 semi-structured interviews were conducted in the northern Canadian communities of Stony Rapids and Black Lake, Saskatchewan. All participants had an obstetrical or non-obstetrical ultrasound exam performed in the past 10 years. Interviews were audio recorded and interview transcripts were analysed using constant comparative analysis. Geographic isolation from imaging facilities was a central barrier to participants accessing ultrasound imaging. Other barriers became apparent when participants had to travel for ultrasound, including fear of air travel, isolation from family, financial means, and unfamiliarity with larger cities. Barriers such as family and work responsibilities were exacerbated by the barrier of geography. Participants overcame these barriers as they were motivated by potential diagnostic benefits of ultrasound imaging. This study highlights disparities in access to ultrasound for northern, remote, Indigenous populations. Future efforts to improve access to imaging should consider barriers of distance to imaging facilities and strategies to bridge these barriers. [ABSTRACT FROM AUTHOR]

Objective: Obesity increases the difficulty of completing the fetal anatomic survey. This is of added concern in obese gravidas who are at higher risk of congenital fetal anomalies. We hypothesized that incorporation of an early transvaginal assessment could improve the completion rate of the fetal anatomic survey in obese women. Methods: We performed a prospective, longitudinal, blinded study of obese gravidas (BMI ≥ 35 kg/m2) comparing the use of a single early second trimester transvaginal ultrasound in addition to midtrimester transabdominal ultrasound versus traditional serial midtrimester ultrasound alone for completion of the anatomic survey. Transvaginal ultrasound for anatomy was performed between 13 0/7 and 15 6/7 week followed by midtrimester anatomic ultrasound, with each patient serving as her own control. Structures were marked as optimally or suboptimally viewed after each ultrasound. Sonographers and reviewers were blinded to images from the transvaginal ultrasound. Completion rates and gestational age at completion were compared between groups. Results: Fifty subjects were included. Fetal anatomic survey was completed in 62% using standard midtrimester assessment versus 78% with the addition of early transvaginal assessment (p =.04). The survey was completed at an earlier gestational age utilizing the transvaginal approach (22 0/7 ± 6 3/7) compared to traditional midtrimester transabdominal ultrasound approach (25 2/7 ± 5 3/7) p <.0005. Conclusions: Incorporation of an early transvaginal assessment of anatomy in obese women improved the rate of completion and led to earlier gestational age at completion of the fetal anatomic survey. Consideration should be given to including an early transvaginal sonogram as part of routine assessment of women with a BMI ≥ 35. [ABSTRACT FROM AUTHOR]

Superb Micro-vascular Imaging (SMI; Toshiba Medical Systems, Tokyo) is a new blood flow imaging technique that employs a unique algorithm to minimize motion artifacts by eliminating signals based on analysis of tissue movement. Compared to conventional blood flow imaging such as color and power Doppler imaging, SMI significantly reduces motion artifacts and can visualize low-velocity blood flow in small vessels. In the present report, the clinical value and future potential of SMI in obstetrics have been demonstrated for the first time. We believe this new blood flow imaging technique is acceptable for obstetricians for the purpose of perinatal clinical assessments. [ABSTRACT FROM PUBLISHER]

Foetal magnetic resonance imaging (MRI) plays an increasingly important role in the diagnosis of foetal abnormalities. Over the years, we have successfully applied bi-parametric MRI (bp-MRI) to the following obstetric conditions: (1) neurologic vascular diseases; (2) assessment of lung parenchyma maturation; (3) renal pathologies, such as polycystic kidney, suspected renal infarction, unilateral or bilateral renal agenesis; (4) placental pathologies, as twin-twin transfusion syndrome or placenta accreta; (5) benignant and malignant congenital tumours or cysts of the liver, such as haemangioendothelioma, hepatoblastoma or metastatic neuroblastoma, of the kidney (e.g. mesoblastic nephroma) and of the retroperitoneum, such as teratoma. The information derived from bp-MRI, and concerned with water motions in different tissues, improved the morphologic details provided by conventional foetal MRI. It has the potential to increase the value of MRI in the assessment of a wide range of foetal pathologies, particularly in renal diseases, allowing an adequate management decision and therapy.

Purpose: The purpose of our study is to present clinical courses and outcomes of 50 first-trimester cesarean scar pregnancy (CSP) cases, which are managed either with transabdominal ultrasound (TAUS)-guided suction curettage alone or abdominal hysterotomy. Methods: We retrospectively analyzed our records from 2011 to 2016 at a single-center. TAUS-guided suction curettage alone was preferred in hemodynamically stable patients when the myometrial thickness was ≥3 mm and there was no vascular invasion. If the myometrial thickness was <3 mm and/or vascular invasion was present, then hysterotomy was preferred. Results: Statistical analysis of age, gravidity, parity, history of previous CS (≥3 or <3), presence of embryonic cardiac activity, complaints (vaginal bleeding, pelvic pain, or both), preoperative and postoperative hemoglobin levels (g/dl), blood transfusion, initial serum β-hCG levels, and duration to resolution of β-hCG demonstrated no significant difference between TAUS-guided suction curettage and abdominal hysterotomy groups. There was a significant difference between two groups in terms of postoperative length of stay in the hospital and gestational age. Conclusion: TAUS-guided suction curettage in selected cases may be considered as a reliable first-line treatment option due to its low cost, ease of application, lower side-effect profile, and potentially minimal influence on future fertility in CSP patients that are hemodynamically stable.

Fetal malformations of the central nervous system are among the most common major birth defects encounter during prenatal ultrasound screening. Patients with fetal intracranial findings require further work-up for improving the accuracy of the sonographic diagnosis. We developed and advanced fetal neurosonography and related services to improve clinical care and to positively impact the fetal outcome. Currently, dedicated neurosonography in the prenatal period is not routinely offered across all prenatal diagnostic centers. We propose that dedicated neurosonography done in advanced prenatal diagnostic centers improves fetal outcomes. This is directly related to proper counseling, pediatric and neonatal involvement during the prenatal period. We present here our model of dedicated neurosonography adapted to our center in the last 4 years to improve diagnosis and better understand fetal CNS pathology. With commitment of resources and coordination of services, this model is easy to implement and benefits not only parents and babies but also provides the maternal fetal medicine fellows advanced training in fetal neurosonography.
