Isolated Increased Nuchal Translucency in First Trimester Ultrasound Scan: Diagnostic Yield of Prenatal Microarray and Outcome of Pregnancy.

Background: Increased nuchal translucency (NT) is associated with aneuploidy. When the karyotype is normal, fetuses are still at risk for structural anomalies and genetic syndromes. Our study researched the diagnostic yield of prenatal microarray in a cohort of fetuses with isolated increased NT (defined as NT ≥ 3.5 mm) and questioned whether prenatal microarray is a useful tool in determining the adverse outcomes of the pregnancy. Materials and Methods: A prospective study was performed, in which 166 women, pregnant with a fetus with isolated increased NT (ranging from 3.5 to 14.3 mm with a mean of 5.4 mm) were offered karyotyping and subsequent prenatal microarray when karyotype was normal. Additionally, all ongoing pregnancies of fetuses with normal karyotype were followed up with regard to postnatal outcome. The follow-up time after birth was maximally 4 years. Results: Totally, 149 of 166 women opted for prenatal testing. Seventy-seven fetuses showed normal karyotype (52%). Totally, 73 of 77 fetuses with normal karyotype did not show additional anomalies on an early first trimester ultrasound. Totally, 40 of 73 fetuses received prenatal microarray of whom 3 fetuses had an abnormal microarray result: two pathogenic findings (2/40) and one incidental carrier finding. In 73 fetuses with an isolated increased NT, 21 pregnancies showed abnormal postnatal outcome (21/73, 28.8%), 29 had a normal outcome (29/73, 40%), and 23 were lost to follow-up (23/73, 31.5%). Seven out of 73 live-born children showed an adverse outcome (9.6%). Conclusions: Prenatal microarray in fetuses with isolated increased NT had a 5% (2/40) increased diagnostic yield compared to conventional karyotyping. Even with a normal microarray, fetuses with an isolated increased NT had a 28.8% risk of either pregnancy loss or an affected child.

Prenatal sonographic features can accurately determine parental origin in triploid pregnancies.

OBJECTIVE: To describe the prenatal sonographic features and maternal biochemical markers in triploid pregnancies and to assess whether prenatal phenotype can determine genetic origin. METHODS: We performed a retrospective multicenter cohort study that included all triploid pregnancies diagnosed between 2000 and 2018 in two Fetal Medicine Units in Amsterdam. Fetal growth, presence of structural anomalies, extra-fetal anomalies, and maternal biochemical markers were retrieved. Asymmetrical intrauterine growth restriction was diagnosed when the head-to-abdominal circumference (HC/AC) ratio was >95th centile. Parental origin was analyzed via molecular genotyping in 46 cases (38.3%). RESULTS: One hundred and twenty triploid pregnancies were identified, of which 86 cases (71.6%) were detected before 18 weeks of gestation. Triploidy of maternal origin was found in 32 cases (69.6%) and was associated with asymmetrical growth restriction, a thin placenta, and low pregnancy-associated plasma protein A and free beta-human chorionic gonadotrophin (ß-hCG) levels. Triploidy of paternal origin was found in 14 cases (30.4%) and was associated with an increased nuchal translucency, placental molar changes, and a high free ß-hCG. Prospective prediction of the parental origin of the triploidy was made in 30 of the 46 cases based on phenotypical ultrasound presentation, and it was correct in all cases. CONCLUSION: Asymmetrical growth restriction with severe HC/AC discrepancy is pathognomonic of maternal triploidy. Placental molar changes indicate a paternal triploidy. Moreover, triploidy can present with an abnormal first trimester combined test, with serum levels on the extreme end. When available results of maternal serum markers can support the diagnosis of parental origin of the triploidy, an accurate assessment of the parental origin based on prenatal sonographic features is possible, making DNA analysis redundant.

Effect of education and attitude on health professionals' knowledge on prenatal screening.

INTRODUCTION: Ongoing developments in prenatal anomaly screening necessitate continuous updating of counsellors' knowledge. We explored the effect of a refresher counselling course on participants' knowledge of prenatal screening. METHODS: We investigated the association between knowledge and counsellors' working experience. Also, the association between knowledge and counsellors' attitude towards prenatal screening was determined. All counsellors in the North-West region of the Netherlands were invited to attend a refresher counselling course and fill in both a pre-course and a post-course questionnaire. The participants consisted of midwifes, sonographers and gynaecologists. A 55-item questionnaire assessed pre-course (T0) and post-course (T1) knowledge. At T0, counsellors' attitude towards the prenatal screening program was assessed and its association with knowledge analysed. RESULTS: Of 387 counsellors, 68 (18%) attended the course and completed both questionnaires. Knowledge increased significantly from 77.7% to 84.6% (p<0.01). Scores were lowest regarding congenital heart diseases. Participants with ultrasound experience scored higher on T0, but improvement was seen in participants with and without ultrasound experience. Participants with a positive attitude towards a free-of-charge first trimester combined test had higher knowledge scores than participants with a negative attitude (62% vs 46%; p=0.002). CONCLUSIONS: A refresher course improved counsellors' knowledge on prenatal screening. Ultrasound experience and a positive attitude towards free screening may be associated with higher knowledge levels. Participating in a mandatory refresher counselling course is useful for the continuous improvement of healthcare practitioners' knowledge. More research on the effect of knowledge and attitude on the quality of prenatal screening is necessary.

Standardization of compounded oral liquids for pediatric patients in Michigan.

PURPOSE: The development, dissemination, and adoption of standard concentrations for compounded oral liquids for pediatric patients in Michigan are described. SUMMARY: A baseline assessment of current practices in Michigan revealed significant variations in the concentrations of commonly used oral liquid medicines for pediatric patients. A statewide collaborative initiative in Michigan was created to standardize the concentrations of compounded oral liquids for pediatric patients. Standard concentrations were proposed and adopted by key stakeholders. These standards were then disseminated across the state to prescribers and pharmacists, with encouragement to voluntarily adopt the standards as a patient safety measure. A follow-up survey was conducted to evaluate adoption of the standards. A total of 263 pharmacists responded to the survey. Standardization of the concentrations of compounded oral liquids in Michigan was welcomed by most pharmacies and is perceived to have reduced the risk for errors at transitions of care for children receiving compounded oral liquids. Awareness of the standardization initiative was acknowledged by 77% of survey respondents, and adoption of the standards was observed to some degree by 57% of survey respondents. In addition, 70% of survey respondents agreed or strongly agreed that adoption of the standards has improved patient safety in Michigan. CONCLUSION: Standard drug concentrations for compounded oral liquids were developed for pediatric patients in Michigan. A survey after dissemination of the recommended standards confirmed general awareness of the initiative and adoption of the standards by a substantial proportion of respondents. Most respondents indicated a belief that creation of the standards improved patient safety.

Selenium Pretreatment for Mitigation of Ischemia/Reperfusion Injury in Cardiovascular Surgery: Influence on Acute Organ Damage and Inflammatory Response.

Ischemia/reperfusion injury (IRI) contributes to morbidity and mortality after cardiovascular surgery requiring cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). Multi-organ damage is associated with substantial decreases of blood selenium (Se) levels in patients undergoing cardiac surgery with CPB. We compared the influence of a dietary surplus of Se and pretreatment with ebselen, a mimic of the selenoenzyme glutathione peroxidase, on IRI-induced tissue damage and inflammation. Male Wistar rats were fed either a Se-adequate diet containing 0.3 ppm Se or supplemented with 1 ppm Se (as sodium selenite) for 5 weeks. Two other groups of Se-adequate rats received intraperitoneal injection of ebselen (30 mg/kg) or DMSO (solvent control) before surgery. The animals were connected to a heart-lung-machine and underwent 45 min of global ischemia during circulatory arrest at 16 °C, followed by re-warming and reperfusion. Selenite and ebselen suppressed IRI-induced leukocytosis and the increase in plasma levels of tissue damage markers (AST, ALT, LDH, troponin) during surgery but did not prevent the induction of proinflammatory cytokines (IL-6, TNF-α). Both Se compounds affected phosphorylation and expression of proteins related to stress response and inflammation: Ebselen increased phosphorylation of STAT3 transcription factor in the heart and decreased phosphorylation of ERK1/2 MAP kinases in the lungs. Selenite decreased ERK1/2 phosphorylation and HSP-70 expression in the heart. Pretreatment with selenite or ebselen protected against acute IRI-induced tissue damage during CPB and DHCA. Potential implications of their different actions with regard to molecular stress markers on the recovery after surgery represent promising targets for further investigation.

Comparison and alignment of an academic medical center's strategic goals with ASHP initiatives.

PURPOSE: An academic medical center's strategic goals were compared and aligned with the 2015 ASHP Health-System Pharmacy Initiative and the Pharmacy Practice Model Initiative (PPMI). METHODS: The department's pharmacy practice model steering committee identified potential solutions to narrow prioritized gaps using a modified nominal group technique and a multivoting dot technique. RESULTS: Five priority solutions were identified and assigned to work groups to develop business plans, which included admission medication history and reconciliation for high-risk patients and those with complex medication regimens, pharmacist provision of discharge counseling to high-risk patients and those with complex medication regimens, improved measurement and reporting of the impact of PPMI programs on patient outcomes, implementation of a departmentwide formalized peer review and evaluation process, and the greeting of every patient at some time during his or her visit by a pharmacy team member. Stakeholders evaluated the business plans based on feasibility, financial return on investment, and anticipated safety enhancements. The solution that received the highest priority ranking and was subsequently implemented was "improved measurement and reporting of the impact of PPMI programs on patient outcomes." CONCLUSION: A defined process was followed for identifying gaps among current practices at an academic medical center and the 2015 ASHP Health-System Pharmacy Initiative and the PPMI. A key priority to better document the impact of pharmacists on patient care was identified for our department by using a nominal group technique brainstorming process and a multivoting dot technique and creating standardized business plans for five potential priority projects.

Nursing, Pharmacy, and Prescriber Knowledge and Perceptions of High-Alert Medications in a Large, Academic Medical Hospital.

BACKGROUND: High-alert medications pose a greater risk of causing significant harm to patients if used in error. The Joint Commission requires that hospitals define institution-specific high-alert medications and implement processes to ensure safe medication use. METHOD: Nursing, pharmacy, and prescribers were asked to voluntarily complete a 34-question survey to assess their knowledge, experience, and perceptions regarding high-alert medications in an academic hospital. RESULTS: The majority of respondents identified the organization's high-alert medications, the consequences of an error involving a high-alert medication, and the reversal agent. Most of the risk-reduction strategies within the institution were viewed as being effective by respondents. Forty-five percent of the respondents utilized a high-alert medication in the previous 24 hours. Only 14.2% had experienced an error with a high-alert medication in the previous 12 months, with 46% being near misses. The survey found the 5 rights for medication administration were not being utilized consistently. Respondents indicated that work experience or hospital orientation is the preferred learning experience for high-alert medications. CONCLUSIONS: This study assessed all disciplines involved in the medication use process. Perceptions about high-alert medications differ between disciplines. Ongoing discipline-specific education is required to ensure that individuals accept accountability in the medication use process and to close knowledge gaps on high-alert medications and risk-reduction strategies.

Integrating a new medicinal chemistry and pharmacology course sequence into the PharmD curriculum.

OBJECTIVE: To evaluate the implementation of an integrated medicinal chemistry/pharmacology course sequence and its alignment with a therapeutics series. DESIGN: Each topic was divided into modules consisting of 2-hour blocks, and the content was integrated and aligned with the therapeutics series. Recitation sessions emphasizing application skills in an interactive environment followed each of three 2-hour blocks. To ensure that students achieved competency in each unit, students failing any unit examination were encouraged to undergo remediation. ASSESSMENT: Student feedback was collected by an independent researcher through social media and focus groups and relayed anonymously to course directors for midcourse improvements. Responses from surveys, interviews, and student ratings of faculty members and of courses were used to implement changes for future editions of the courses. CONCLUSION: The majority of students and faculty members felt the integration and alignment processes were beneficial changes to the curriculum. Elements of the new sequence, including remediation, were viewed positively by students and faculty members as well.

A cardiopulmonary bypass with deep hypothermic circulatory arrest rat model for the investigation of the systemic inflammation response and induced organ damage.

BACKGROUND: Cardiopulmonary bypass (CPB) is a commonly used technique in cardiac surgery. CPB is however associated with a strong induction of systemic inflammatory response syndrome (SIRS) which in conjunction with ischemia and reperfusion may lead to multiple organ failure. The aim of the study was to establish and characterize a CPB rat model incorporating deep hypothermic circulatory arrest with a specific focus on the extent of the inflammatory reactions and organ damage as a groundwork for novel therapeutics against SIRS and I/R induced organ injury. MATERIALS AND METHODS: Male Wistar rats (n = 6) were cannulated for CPB, connected to a heart-lung-machine (HLM) and cooled to a temperature of 16°C before they underwent 45 minutes of deep hypothermic circulatory arrest with global ischaemia. Arrest was followed by rewarming and 60 minutes of reperfusion. Haemodynamic and vital parameters were recorded throughout the CPB procedure. Only animals displaying sinus rhythm throughout reperfusion were utilized for analysis. Rats were euthanized and tissue samples were harvested. Blood gas analysis was performed and blood samples were taken. Induction of organ damage was examined by analysis of protein levels and phosphorylation status of kinases and stress proteins. Results were compared to animals (n = 6) which did not undergo CPB. RESULTS: CPB induced leucocytosis and an increase of interleukin-6 and TNF-α plasma values indicating an inflammatory response. Markers of tissue damage and dysfunction, such as troponin T, creatinine and AST were elevated. Phosphorylation of STAT3 was induced in all examined organs. Activation of MAPK and induction of heat shock proteins occurred in an organ-specific manner with most pronounced effects in heart, lungs and kidneys. CONCLUSIONS: The presented CPB rat model shows the induction of SIRS and activation of specific signalling cascades. SIRS seems not to be provoked during DHCA and is elicited mainly during reperfusion. This model might be suitable to test the efficacy of therapeutics applied in major heart surgery with and without DHCA.

First-trimester screening for down syndrome with serum sampling at different gestational ages: the effect on screening performance.

INTRODUCTION: The objective of this study was to evaluate the performance of first-trimester Down syndrome (DS) screening with serum sampling at different weeks of gestation. MATERIAL AND METHODS: We studied 35,431 singleton pregnancies (2005-2011), including 145 DS cases. Screening performance was determined in different maternal age groups with serum sampling between weeks 9 + 0 and 13 + 6. RESULTS: No significant differences were found between the detection rates at different gestational weeks. The false-positive rate (FPR) in week 9 (6%) was comparable to the FPR in week 10 (6.5%; p = 0.214), whereas it was significantly lower compared to weeks 11 (7.2%; p = 0.007), 12 (7.4%; p = 0.003) and 13 (8.5%; p < 0.001). The odds of receiving a false-positive result was significantly increased with serum sampling in week 11 (OR 1.32, 95% CI 1.08-1.63; p = 0.008) for women ≥36 years and from week 12 onwards (OR 1.28, 95% CI 1.01-1.61; p = 0.04) for women <36 years. There were no differences in mean log10 multiple of the median values of pregnancy-associated plasma protein-A, free ß-human chorionic gonadotrophin or nuchal translucency between both age groups, nor in mean maternal age between the different gestational weeks in either age group. DISCUSSION: Early serum sampling (<11 weeks) resulted in higher screening performance. The impact of the increase in the FPR was highest in women ≥36 years.

Variability in compounding of oral liquids for pediatric patients: a patient safety concern.

OBJECTIVE: To determine the degree in variation of oral liquid pediatric compounding practices in Michigan pharmacies. DESIGN: Cross-sectional survey study. SETTING: All types of inpatient and outpatient pharmacies across the state of Michigan, excluding nuclear pharmacies and long-term care facilities. PARTICIPANTS: 244 Michigan pharmacies. INTERVENTION: An online survey tool was used to assess the current compounding practices of 147 oral liquid pediatric medications. The survey was e-mailed or faxed to hospitals, chain pharmacies, and independent pharmacies. Pharmacists were also mailed a follow-up postcard, and the Michigan Pharmacists Association publicized the project through its journal and annual meeting. MAIN OUTCOME MEASURES: Pharmacy demographics; number of compounding pharmacies; number of medications compounded; awareness of compounding errors; results of compounding errors; and number of concentrations compounded per medication. RESULTS: The majority of respondents were from outpatient pharmacies, but inpatient and other types of pharmacies were also represented. The majority of participating pharmacies compound fewer than five oral liquid medications per week. Awareness of errors was low overall, with no errors believed to result in permanent harm or death. The number of concentrations compounded per medication ranged from 1 to 9, with the majority of pharmacies compounding more than 3 concentrations per medication. CONCLUSION: There is a considerable degree of variation in current oral pediatric liquid compounding practices in Michigan pharmacies. This variability poses a significant risk to patient safety.

The effectiveness of multifetal pregnancy reduction in trichorionic triplet gestation.

OBJECTIVE: The objective of the study was to assess in trichorionic triplet pregnancies the effectiveness of elective reduction to twins. STUDY DESIGN: This was a nationwide retrospective cohort study. We compared the time to delivery and perinatal mortality in trichorionic triplet pregnancies electively reduced to twins with ongoing trichorionic triplets and primary dichorionic twins. RESULTS: We identified 86 women with reduced trichorionic triplet pregnancies, 44 with ongoing trichorionic triplets, and 824 with primary twins. Reduced triplets had a median gestational age at delivery of 36.1 weeks (interquartile range [IQR], 33.3-37.5 weeks) vs 33.3 (IQR, 28.1-35.2) weeks for ongoing triplets and 37.1 (IQR, 35.3-38.1) weeks for primary twins (P < .001). The total number of surviving children in the reduced group was 155 (90%) vs 114 (86%) in the ongoing triplet group. After reduction, 75 of women (87%) had all their fetuses surviving, compared with 36 (82%) (relative risk [RR], 1.3; 95% confidence interval [CI], 0.72-2.3) for ongoing triplets and 770 (93%) (RR, 0.91; 95% CI, 0.82-1) for primary twins. There were 6 women without any surviving children (7%) after reduction vs 5 (11.4%) (RR, 0.81; 95% CI, 0.47-1.4) among women with ongoing triplets and 32 (3.9%) (RR, 1.7; 95% CI, 0.8-3.7) in women with primary twins. CONCLUSION: In women with a triplet pregnancy, fetal reduction increases gestational age at birth with 3 weeks as compared with ongoing triplets. However, there the impact on neonatal survival is limited.

Evaluation of the introduction of the national Down syndrome screening program in the Netherlands: age-related uptake of prenatal screening and invasive diagnostic testing.

OBJECTIVE: To study the effect of different government prenatal screening (PNS) policies on the uptake of PNS and prenatal diagnostic testing (PND) over the periods 2001-2003 (PNS on request), 2004-2006 (permission to offer the first-trimester combined test (FCT) to women of advanced maternal age (AMA), with women aged <36 years informed on explicit request) and 2007-2010 (introduction of population screening) and to evaluate whether trends in uptake are related to maternal age. The indication AMA for PND is still warranted, and the costs for FCT are only reimbursed for AMA women. STUDY DESIGN: Analysis of data on the first- and second-trimester screening program (n=41,600) for Down syndrome (DS) and on PND (n=10,795) performed from 2001 to 2010 in the region North-Holland of the Netherlands. To evaluate the actual participation in PNS and PND in different maternal age groups, estimation of the age distribution of women who underwent a fetal anomaly scan in 2009 (n=14,481) was used as a reference population (participation of 85.2%). RESULTS: The overall uptake of FCT was 35.2% in 2010. Over the years the number of FCT in all age groups increased significantly (P<0.001). Overall the number of PND decreased significantly; the number of PND for AMA decreased and the number of PND for increased risk at FCT (in women <36 and ≥36 years) increased (P<0.05). Since 2004 significantly more DS cases were detected with FCT in AMA women and fewer with PND for AMA, and since 2007 more DS cases were detected with FCT in women <36 years (P<0.001). CONCLUSION: The effect of the national screening program is limited. Significantly more women opt for PNS but the overall uptake remains low, especially in younger women. A significant number of AMA women still opt for PND for AMA. The choice for FCT and PND for AMA seems dependent on background risk. To accomplish a more effective screening policy, reimbursement of the cost of the test should apply to all women and the indication for PND for AMA should be abolished.

Validation of correction factors for serum markers for first-trimester Down syndrome screening in singleton pregnancies conceived with assisted reproduction.

OBJECTIVE: To validate previously computed correction factors for free ß-human chorionic gonadotrophin (fß-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) pregnancies with hormone treatment and to determine the effect on false-positive rate (FPR). METHODS: Retrospective study on 249 IVF and 250 ICSI cases and 20,190 controls. Correction factors 1.42 (PAPP-A), 1.17 (fß-hCG) in IVF; 1.56 (PAPP-A) in ICSI were applied on the absolute serum concentrations. Analysis was done on log10-transformed multiples of medians (MoMs). RESULTS: In the controls, mean PAPP-A and fß-hCG MoM were 1.004 and 1.062. Before correction, mean PAPP-A MoM was significantly lower in IVF (0.757; p < 0.001) and in ICSI (0.671; p < 0.001) and after correction comparable (1.071; p = 0.053 in IVF; 1.048; p = 0.178 in ICSI). Before correction, mean fß-hCG MoM was comparable (1.054; p = 0.59 in IVF and 1.051; p = 0.56 in ICSI) and after correction significantly higher in IVF (1.241; p < 0.001). After correction the likelihood for receiving a false-positive result was 1.03 in IVF pregnancies (95% CI 0.98-1.09; p = 0.248) and 1.02 in ICSI pregnancies (95% CI 0.97-1.07; p = 0.448). CONCLUSIONS: After correction the FPR in IVF and ICSI pregnancies with hormone treatment reduces to the observed FPR in the controls.

Performance of first-trimester combined test for Down syndrome in different maternal age groups: reason for adjustments in screening policy?

OBJECTIVE: To evaluate the performance of the first-trimester combined test (FCT) in different maternal age groups and to discuss whether adjustments in screening policies should be made. METHODS: In this retrospective study data (n = 26 274) from a fetal medicine center on FCT (maternal age, fetal NT, free ß-human chorionic gonadotrophin, pregnancy-associated plasma protein-A) were studied. RESULTS: 70.6% of cases was <36 years and 43% of the Down syndrome (DS) cases were detected in this age group. For women <36 years and advanced maternal age (AMA) women (≥36 years) detection rate (DR) and false positive rate (FPR) were 94.5% and 4.1%, and 95.8% and 13.0%, respectively (cut-off 1:200). Lowering the cut-off showed an improved balance in DR and FPR. With increasing maternal age FPR and DR increased and odds of being affected given a positive result (OAPR) decreased. CONCLUSION: FCT is effective in women <36 and ≥36 years. The balance between FPR and DR is more favourable in women <36 years with comparable OAPR. Although FPR increases with increasing maternal age, performance of FCT in AMA women is more effective than screening based on maternal age alone. Lowering the cut-off to 1:100 in AMA women is suggested to improve screening performance. Routinely offering diagnostic testing to AMA women as a screening policy for the detection of DS seems not reasonable.

Small for gestational age children without early catch-up growth: spontaneous growth and prediction of height at 8 years.

BACKGROUND/AIM: About 10-15% of children born small for gestational age (SGA) have at the age of 2 years a height standard deviation score (HSDS(2y)) still below -2. There is no model to predict which children will catch up in height after 2 years of age. The aim of this study was to determine the percentage of children with catch-up growth to a normal height after the age of 2 years and to develop a prediction model for growth after that age. METHODS: In a cohort of 724 SGA children, the percentage of children with HSDS above -2 at 8 years of age was determined. In data of 97 children with HSDS(2y) below -2, a prediction model was developed for growth between 2 and 8 years. RESULTS: Thirty-nine percent of children with HSDS(2y) below -2 reached an HSDSabove -2 between 2 and 8 years (6% of the total group). Determinants of growth after age 2 years, all with a positive influence, were the difference between target height SDS and HSDS(2y), change in height SDS during first 2 years of life, female gender and multiple birth. CONCLUSIONS: Catch-up growth to a normal height occurred in 91% of SGA children, in 6% between 2 and 8 years of age. The difference between target height SDS and HSDS(2y) was the most important determinant. The presented prediction model can identify children with low or high probability of catch-up growth after the age of 2 years. This may assist to determine which children require medical follow-up.

Prenatal diagnosis of aneurysms of the vein of Galen (vena magna cerebri) with conventional sonography, three-dimensional sonography, and magnetic resonance imaging: report of 2 cases.

OBJECTIVE: To describe the cases of 2 fetuses with aneurysms of the vein of Galen diagnosed prenatally. METHODS: The techniques used were conventional sonography, three-dimensional sonography, and ultrafast magnetic resonance imaging. On the basis of these imaging modalities, prognostic factors, such as drainage and secondary damage, were assessed. RESULTS: The first fetus had good prognostic indices, and embolization after birth was successful. According to the prognostic factors, a poor neonatal outcome was predicted for the second fetus. The neonate died soon after birth. CONCLUSIONS: Conventional sonography, color Doppler imaging, and magnetic resonance imaging appeared to be useful diagnostic tools. The prognostic factors can be useful in counseling patients and providing the best possible care after birth.
