Abstract
OBJECTIVE This article aimed to evaluate pregnancy outcomes when a plan to perform fetal blood sampling (FBS) or delivery was based solely on the first abnormal middle cerebral artery peak velocity (MCA-PV) measurement compared with making a plan after a confirmatory test on a subsequent day. STUDY DESIGN We performed a descriptive study of pregnancy outcomes including all patients in a single healthcare system with maternal red cell alloimmunization undergoing ultrasound between 2005 and 2017 who had at least one MCA-PV>1.5 multiples of the median (MoM). We excluded patients with any sign of hydrops prior to the index visit or abnormal MCA-PV at>35 weeks. The first exam with a MCA-PV>1.5 MoM was deemed the index visit. RESULTS Fifty patients were identified. Twenty-one patients underwent intervention (FBS or delivery) based on the first abnormal MCA-PV. Of those, 9 had moderate or severe anemia (positive predictive value [PPV]: 43%), while 12 had mild or no anemia. The other 29 patients underwent a confirmatory MCA test between 2 and 8 days later. Of these, 13 patients had an abnormal confirmatory test and 11 of these underwent FBS and 7 had moderate or severe anemia (PPV: 54%). Sixteen patients undergoing confirmatory MCA Doppler had a normal test on repeat and did not undergo FBS. Of those, none developed moderate or severe anemia. CONCLUSION A substantial number of patients (55%) had normal MCA-PV testing on repeat, allowing avoidance of invasive testing. Deferring FBS until the abnormal MCA-PV was confirmed was not associated with undetected moderate or severe anemia. KEY POINTS · False-positive results from MCA-PV Doppler prediction of fetal anemia are common.. · Repeat noninvasive testing is normal in many patients with suspected fetal anemia.. · Invasive fetal testing can often be safely avoided by performing a confirmatory Doppler exam ination..

Abstract
Contrary to its widespread use in human cases, the use of Doppler ultrasonography is only recently becoming prevalent in farm animals. This study aimed to determine the effects of maternal metabolic and clinical changes on fetal hemodynamics during pregnancy toxemia with the doppler examination of umbilical cord. In the study twenty ewes with a single healthy fetus were included in the study. At the end of the 120th day of pregnancy, 20 single-bearing pregnant ewes were randomly categorized into two groups. Ewes in the control group were fed to meet all nutritional requirements. On the other contrary, the experimental ewes were fed to meet equivalent to 50 % of the daily needs and then fasted for 96 h. Doppler ultrasonographic examinations of umbilical cord were performed once every two days and once a day during fasting. Beta hydroxybutyric acid (BHBA) concentration was measured by taking blood from sheep on examination days. Pulse systolic velocity (PSV), end diastolic velocity (EDV), PSV/EDV, pulsatility index (PI), resistance index (RI), and fetal heart rate (FHR) as well as BHBA values and how those parameters has changed over time (time by treatment effect) due to energy deprivation during pregnancy were evaluated using repeated measure analysis of variance. No clinical signs were observed in both toxemia and control groups during restricted feeding. BHBA concentration increased and there was a significant time, time by treatment and main effect of treatment effect between groups. No significant main effect of treatment and time by treatment interaction was observed in the changes of PI, RI, FHR, and systolic/diastolic velocity values over time in both groups. FHR was reduced over time, and there was a significant time effect in FHR in both groups. Although doppler indices didn't increase, both PSV and EDV values increased significantly in the pregnancy toxemia group compared with the controls (Time P = 0.03, time by treatment interaction P < 0.05) and the main effect of treatment P < 0.05). The marked increase in blood velocities (PSV and EDV) in the umbilical cord is probably due to the compensatory functioning for excessive energy deprivation of the fetus. Therefore, PSV and EDV might be a valuable indicator for evaluating the fetus's health status during the management of the PT.

Abstract
OBJECTIVE The aim of this study was to investigate the role of middle cerebral artery (MCA) Doppler measurements for the prediction of abnormal neonatal outcomes in pregnancies affected by Zika virus (ZIKV). METHODS Secondary analysis of a prospective cohort of pregnant women diagnosed with ZIKV infection from September 2015 to December 2016 at a single regional referral center. Ultrasonography with measurements of MCA peak systolic velocity (PSV), PSV multiples of the median (MoM) for gestational age, and pulsatility index (PI) were collected. The primary outcome was a composite abnormal neonatal outcome. MCA Doppler values of normal and abnormal neonatal outcomes were compared with Wilcoxon rank sum test. The predictive value of MCA Dopplers for development of abnormal neonatal outcome was calculated by logistic regression. RESULTS One-hundred twenty-seven ZIKV-positive pregnancies with MCA Doppler measurements and known neonatal outcomes were included. Of the 132 neonates, 66 (50%) had an abnormal neonatal outcome. Lower MCA PSV (p = 0.027) and PSV MoM (p = 0.008) were associated with abnormal neonatal outcomes. There was no significant difference in MCA PI. Abnormal neonatal outcomes had lower MCA PSV by 5.36 cm/s (95% confidence interval [CI]: 0.95-9.77, p = 0.018) and lower MCA PSV MoM by 0.13 (95% CI: 0.05-0.22, p = 0.002). MCA PSV of 30 cm/s had a 65% predicted probability of an abnormal neonatal outcome (95% CI: 51-79%). CONCLUSION In ZIKV-infected pregnancies, lower MCA PSV and PSV MoM measurements were seen with abnormal neonatal outcomes. This may represent a physiologic response to fetal ZIKV infection. Evaluation of MCA Dopplers may be of clinical utility in the surveillance of ZIKV-affected pregnancies. KEY POINTS · Significantly lower MCA PSV is associated with abnormal neonatal outcomes in ZIKV pregnancies.. · Lower MCA PSV may reflect the underlying neuropathology of ZIKV exposure on the fetus.. · There is potential utility for MCA Doppler evaluation in antepartum surveillance of ZIKV pregnancies..

Abstract
Twin anemia polycythemia sequence (TAPS) is a consequence of unequal sharing of red blood cells between monochorionic twins resulting in anemia in the donor and polycythemia in the recipient twin. Prenatally TAPS can occur spontaneously or complicate incomplete laser surgery for twin transfusion syndrome. While there may be clinical overlap with twin transfusion syndrome or selective fetal growth restriction, diagnosis relies on Doppler measurement of middle cerebral artery peak systolic velocities. Significantly discordant velocities are diagnostic, while severity staging is based on signs of cardiovascular compromise. Conservative management, fetoscopic laser coagulation, selective twin reduction, fetal blood and exchange transfusion, and delivery may be selected guided by the gestational age of diagnosis, the severity of the condition, the likelihood of success, and the patients' priorities. Prenatal curative treatment that minimizes the risk for prematurity and residual morbidity at birth is most likely to offer the greatest short-term and long-term benefits.

Abstract
This second part on Doppler sonography in prenatal medicine and obstetrics reviews its clinical applications. While this has not become the initially anticipated screening tool, it is used for the diagnosis and surveillance of a variety of fetal pathologies. For example, the sonography-based determination of uterine artery blood flow indices is an important parameter for the first trimester multimodal preeclampsia risk assessment, increasing accuracy and providing indication for the prophylactic treatment with aspirin. It also has significant implications for the diagnosis and surveillance of growth-restricted fetuses in the second and third trimesters through Doppler-sonographic analysis of umbilical artery, middle cerebral artery and ductus venosus. Here, especially the hemodynamics of the ductus venosus provides a critical criterium for birth management of severe, early-onset FGR before 34 + 0 weeks of gestation. Further, determination of maximum blood flow velocity of the middle cerebral artery is a central parameter in fetal diagnosis of anemia which has been significantly improved by this analysis. However, it is important to note that the mentioned improvements can only be achieved through highest methodological quality. Importantly, all these analyses are also applied to twins and higher order multiples. Here, for the differential diagnosis of specific complications such as TTTS, TAPS and TRAP, the application of Doppler sonography has become indispensable. To conclude, the successful application of Doppler sonography requires both exact methodology and precise pathophysiological interpretation of the data.

Abstract
Abstract
Objectives
Doppler measurement of fetal middle cerebral artery peak systolic velocity (MCA-PSV) is used to screen fetuses at risk of developing fetal anemia. This screening tool has demonstrated to be accurate to estimate the likelihood of fetal anemia and it has been used in the management of fetuses at this risk. It is rare to find in the literature cases of increased MCA-PSV in the absence of fetal anemia. We present the case of an elevated MCA-PSV in the absence of common causes of fetal anemia.
Case presentation
A 30-year-old woman at 21 weeks of gestation was referred to our unit with a left fetal renal agenesis and single umbilical artery diagnosis. The patient had a poorly controlled type 1 Diabetes with a booking HbA1C of 9.1%. At 31 weeks of gestation, MCA-PSV was raised (>1.5 multiples of the median) in the absence of any cause of fetal anemia and discrepancy of ventricular size with normal fetal heart function were seen. In a subsequent scan, thick interventricular septum was seen and hypertrophic cardiomyopathy (HC) was suggested. Follow-up ultrasonography showed a persistent MCA-PSV in a large for gestation age (LGA) fetus with HC. Due to the prenatal diagnosis of persistent elevated MCA-PSV in LGA fetus with diagnoses of HC in a poorly controlled type 1 diabetic patient labor was induced after fetal lung maturation. Biventricular hypertrophic cardiomyopathy was detected after birth.
Conclusions
HC may be an explanation for increased MCA-PSV without fetal anemia.

Abstract
OBJECTIVES The subject of our analysis is the influence of umbilical cord collision around the fetal neck on the fetal heart function and cerebral circulation. METHODS Our study was carried out on a group of 115 fetuses from single pregnancies with physiological course, during the 15th to 40th week of pregnancy. In our analysis, we examined the following parameters: Tei index for right ventricle, Tei index for left ventricle with Tei index components: isovolumetric contraction time, isovolumetric relaxation time, ejection time and cardiothoracic area ratio, middle cerebral artery peak systolic velocity (PS MCA), middle cerebral artery pulsatility index (PI MCA). Gestational age in our study was: 28+2±34. The study group of patients with fetal umbilical cord around neck group (fUCAN) included 38 fetuses (20 males, 18 females). The control group of patients with no fetal umbilical cord around neck group (NfUCAN) included 77 fetuses (43 males, 34 females). RESULTS In our study, we found no significant differences in the values obtained: Tei LV in fUCAN: 0.5±0.1 vs. in NfUCAN: 0.5±0.1; p=0.42), Tei RV in fUCAN: 0.5±0.2 vs. in NfUCAN: 0.4±0.1; (p=0.2). Tricuspid valve regurgitation-TR was observed with the following frequency: fUCAN: 7/38, 18% vs. NfUCAN: 13/77, 17%; p=0.8. MCA PS in study fUCAN group was significantly higher than in NfUCAN (40.2±11.5 vs. 32.5±9.5; p=0.003), although other hemodynamic and clinical variables did not differ between the study and control groups. CONCLUSIONS The fetal nuchal umbilical cord collision did not affect the fetal heart function expressed as Tei index, at the time of fetal heart examination (at mean gestational age 29+4 weeks). The fUCAN group presented elevated PS MCA, which was not related to other hemodynamic and clinical variables between the study and control groups.

Peak systolic velocity of fetal middle cerebral artery to predict anemia in Red Cell Alloimmunization in un-transfused and transfused fetuses. Eur J Obstet Gynecol Reprod Biol 2021; 258:437-442.

Abstract
OBJECTIVE To assess the accuracy of middle cerebral artery peak systolic velocity (MCA-PSV) in prediction of severe fetal anemia resulting from Red Cell Alloimmunization (Anti-D) in un-transfused and transfused fetuses. In addition to comparing the accuracy of MCA-PSV and the estimation of the daily decline of fetal hemoglobin (Hb), to determine the appropriate time of subsequent transfusions. STUDY DESIGN This was a retrospective study of a series of 84 anaemic fetuses due to Red Cell alloimmunization. During each in-utero transfusion session, measurements of (1)MCA-PSV, (2)pre- and (3)post-transfusion Hb levels were recorded. Receiveroperating characteristics (ROC) curves, negative and positive predictive values of MCA-PSV in predicting severe fetal anemia were calculated. Regression analysis assesses the correlation between fetal HB and MCA-PSV, and between observed and expected fetal hemoglobin levels. RESULTS Eighty four anemic fetuses were included in the study and had an in-utero transfusion. The positive predictive value (PPV) of MCAPSV decreased sharply from 86.0 % at the first IUT, to 52.0 % and 52.1 % at the second and third IUTs respectively. According to the ROC curves, setting the cut-off at 1.70 MoM would provide the best performance of MCA-PSV with respect to the timing of the second and third IUT. Setting a higher threshold of 1.70 MoM for the 2nd and 3rd transfusions would increase the PPV from 52.0 % to 96.4 % at the second IUT, and from 52.1%-99.8 % at the third IUT. CONCLUSION In this study we suggest that a higher MCA-PSV (MoM 1.7 in compared to 1.5MOM) can accurately predict the recurrence of severe fetal anemia requiring serial IUTs. In transfused fetuses, MCAPSV accuracy to detect severe anemia decline slightly with increase number of IUT. In addition to that, the mean projected daily decrease in fetal hemoglobin has a similar accuracy to MCA-PSV in predicting moderate to severe fetal anemia.

Abstract
Fetal Doppler ultrasonography provides an effective and noninvasive approach to identify circulatory abnormalities in the maternal-fetal circulation. It is invaluable to assess the hemodynamic status of the fetus under a wide range of physiologic, infectious, and abnormal anatomic conditions. Findings from these studies are often used to make clinical decisions, including whether to proceed with urgent delivery of the fetus. In this review, we focus on key literature describing the main uses of Doppler ultrasonography in neonatal medicine, including how abnormal findings may be implicated in immediate and long-term outcomes. Our review highlights the importance of fetal Doppler examination as an effective intrauterine management strategy, and its full potential is more likely to be realized when considered in context with other available clinical information.

Abstract
This study evaluates the diagnostic performance of Doppler ultrasound in diagnosing fetal anemia. Data were taken from relevant study reports published in peer-reviewed journals identified after a literature search in electronic databases. Random effects meta-analyses were performed by pooling the effect sizes of diagnostic indices (sensitivity, specificity, positive/negative predictive values, and false-positive rate) or correlation coefficients reported by individual studies. As a result, 31 studies (1848 pregnancies; gestation age, 28.25 weeks [95% confidence interval {CI}, 26.87-29.63]) were included in the meta-analysis. Anemia was found in 63.7% (95% CI, 49.7-77.7) fetuses, and severe anemia was found in 36.7% (95% CI, 26.9-46.4) fetuses. Sensitivity and specificity of Doppler ultrasound for detecting fetal anemia in alloimmunized fetuses at middle cerebral artery peak systolic velocity cutoff of 1.5 multiple of median for gestation age were 83.42% (95% CI, 71.75-95.09) and 80.30% (95% CI, 73.58-87.02), respectively. Positive predictive value, negative predictive value, and false-positive rate were 76.35% (95% CI, 65.98-86.72), 80.0% (95% CI, 76.63-83.37), and 10.4% (95% CI, 5.9-14.9), respectively. Correlation coefficient between hematological anemia and Doppler ultrasound-measured blood flow velocity was -0.706 (95% CI, -0.765 to -0.635; P < 0.00001). In conclusion, Doppler ultrasound-measured middle cerebral artery peak systolic velocity at 1.5 multiple of median provides good diagnostic strength for the detection of alloimmunized fetal anemia. A strong correlation between Doppler velocimetric measures and hematological anemia is also observed.

Abstract
INTRODUCTION Peak systolic velocity (PSV) of the middle cerebral artery (MCA) shows 100% sensitivity for predicting fetal anemia before the first intrauterine transfusion (IUT). However, its ability to predict subsequent transfusions has remained mostly controversial. OBJECTIVES To assess if there is a need to change the threshold of MCA-PSV from 1.5 to 1.69 multiples of the median (MoM) to predict fetal anemia and the need for subsequent IUT. METHODS This is a retrospective audit, wherein case records of mothers who underwent IUT at the Bangalore Fetal Medicine Centre between April 2008 and May 2017 were reviewed; 86 cases were included, and the data were analyzed using MS Excel. The MCA-PSV and pretransfusion Hb were converted into MoM. 40 fetuses that had more than 1 IUT were included in the analysis. -Results: 31/40 fetuses that had >1 IUT had an MCA-PSV >1.5 MoM, of which 29 were anemic according to the post-IUT Hb MoM. 20/29 (69%) had an MCA-PSV >1.69, whereas 9/29 (31%) had an MCA-PSV between 1.5 and 1.69 MoM. Our study shows that changing the MCA-PSV threshold from 1.5 to 1.69 MoM will reduce the detection of fetal anemia and hence the need for repeat IUT by 31%. CONCLUSIONS Increasing the fetal MCA-PSV threshold from 1.5 to 1.69 will miss out one-third of the fetuses that will require a 2nd, 3rd, or 4th IUT. This is more relevant in geographical areas where the parents must travel long distances for IUTs, which are performed in tertiary fetal care centers.

The value of echocardiography and Doppler in the prediction of fetal demise after laser coagulation for TTTS: A systematic review and meta-analysis. Prenat Diagn 2019; 39:838-847. [PMID: 31237967 PMCID: PMC6771838 DOI: 10.1002/pd.5511] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2019] [Revised: 05/09/2019] [Accepted: 06/18/2019] [Indexed: 01/10/2023]
Abstract
This study aimed to investigate the value of echocardiography and Doppler before fetoscopic laser coagulation for twin‐twin transfusion syndrome (TTTS) in the prediction of intrauterine fetal demise (IUFD). We performed a systematic review and meta‐analysis to compare preoperative parameters between fetuses with and without demise after laser surgery. Eighteen studies were included. Recipient twins have an increased risk of demise in case of preoperative absent/reversed flow (A/REDF) in the umbilical artery (odds ratio [OR] 2.76, 95% confidence interval [CI], 1.78‐4.28), absent or reversed a‐wave in the ductus venosus (OR 2.32, 95% CI, 1.70‐3.16), or a middle cerebral artery peak systolic velocity > 1.5 multiples of the median (MoM) (OR 7.59, 95% CI, 2.56‐22.46). In donors, only A/REDF in the umbilical artery (OR 3.40, 95% CI, 2.68‐4.32) and absent or reversed a‐wave in the ductus venosus (OR 1.66, 95% CI, 1.12‐2.47) were associated with IUFD. No association was found between donor‐IUFD and preoperative myocardial performance index (MPI). Two studies found an association between abnormal MPI and recipient demise. With this study, we have identified a set of preoperative Doppler parameters predictive of fetal demise after laser surgery. More research is needed to assess the utility of preoperative echocardiographic parameters such as the MPI in predicting IUFD. What's already known about this topic?
Doppler parameters are associated with fetal demise after laser surgery. Echocardiographic parameters are currently not used in risk stratification.
What does this study add?
A more extensive set of preoperative Doppler parameters is defined to predict post‐laser fetal demise. The utility of preoperative echocardiographic parameters such as the MPI in predicting fetal demise remains unclear.

Abstract
Objective: The aim of this study was to investigate in the fetus the relationship between unexpected high middle cerebral artery peak systolic velocity (middle cerebral artery (MCA) peak systolic velocity (PSV)) values and hemoglobin (Hgb) levels in normal pregnancies without conditions leading to fetal anemia.Material and methods: This was a prospective study of 922 singleton low-risk pregnant women attending the maternity of La Fe Hospital between 35 and 41 weeks. Multiple pregnancies and pregnancies with growth restriction, smallness, macrosomia or conditions leading to fetal anemia were excluded. During each examination, a biometry and a Doppler examination of the umbilical artery pulsatility index (umbilical artery (UA) pulsatility index (PI)), MCA PI and MCA PSV were performed. MCA PSV was converted into multiples of median (MoM), and birth weight (BW) into centiles adjusting for gender. All pregnancies delivered in a 2-week interval since examination. In order to explain Hgb levels at birth, a correlation between MCA PSV MoM and Hgb was performed and Hgb levels of fetuses with normal MCA PSV and abnormal MCA PSV were compared, using 1.3 MoM as cut-off for mild anemia. Finally, a multivariate linear regression analysis was performed including MCA PSV MoM and several Doppler and clinical parameters.Results: The univariate analysis showed no correlation between the MCA PSV MoM and the umbilical artery Hgb (r2 = 0.026, p = .1237) while a weak correlation was found with the umbilical vein Hgb (r2 = 0.0053, p = .027). Also, fetuses with values of MCA PSV MoM <1.3 MoM did not differ in terms of artery and vein Hgb with those presenting values >1.3 MoM (p = .99 and p = .61, respectively). Finally, both prediction models explaining arterial and venous Hgb presented very weak predictive accuracies (R Squared: 0.0965 and R Squared: 0.106) indicating a low possibility to diagnose fetal anemia in otherwise normal fetuses based on clinical and sonographic data.Conclusion: In normal pregnancies that are not suffering from conditions leading to fetal anemia, unexpected high MCA PSV values do not necessarily reflect the presence of this condition. Active management in this circumstance might result in unjustified higher rates of labor induction and operative delivery.

Abstract
PURPOSE To assess the relationship between peak systolic velocity in the middle cerebral artery (MCA-PSV) and fetal hypoxia in diabetic pregnant women requiring insulin therapy. METHODS The data of diabetic pregnant women using insulin who were followed in our departments were reviewed retrospectively. The relationships between MCA-PSV and umbilical cord pO2, pCO2, base deficit, hemoglobin, and birth weight were analyzed. RESULTS A total of 120 cases were included in the final analysis. The median (Q1 - Q3 ) gestational age at Doppler evaluation was 37 weeks 3 days (37-38 weeks and 2 days), and the mean ± SD gestational age at delivery was 38 weeks 4 days ± 3days. The mean ± SD hemoglobin A1c (HbA1c) level was 5.7% ± 1.0% and, median (Q1 -Q3 ) daily total insulin dose was 25 U (10U-48U). There was no statistically significant correlation between MCA-PSV and pH, PO2, PCO2, base deficit, Hb, and birth weight (Spearman correlation, r:-.001[P = .99], r:-.011[P = .90], r:-.052 [P = .51], r: .049[P = .59], r: .049 [P = .59], r: .030 [P = .75], respectively). Using binary logistic regression analysis, no independent factor for the prediction of fetal acidosis (venous pH < 7.23), and metabolic acidosis (base deficit >6.3 mmol/L) was detected. CONCLUSION MCA-PSV is not a good indicator of fetal polycythemia or chronic hypoxia in fetuses of diabetic pregnant women. Fetal well-being should be monitored with other tools in these circumstances.

Abstract
A uniform approach to management of fetal growth restriction (FGR) improves outcome, prevents stillbirth, and allows appropriately timed delivery. An estimated fetal weight below the tenth percentile with coexisting abnormal umbilical artery (UA), middle cerebral artery (MCA), or cerebroplacental ratio Doppler index best identifies the small fetus requiring surveillance. Placental perfusion defects are more common earlier in gestation; accordingly, early-onset (≤32 weeks of gestation) and late-onset (>32 weeks) FGR differ in clinical phenotype. In early-onset FGR, progression of UA Doppler abnormality determines clinical acceleration, while abnormal ductus venosus (DV) Doppler precedes deterioration of biophysical variables and stillbirth. Accordingly, late DV Doppler changes, abnormal biophysical variables, or an abnormal cCTG require delivery. In late-onset FGR, MCA Doppler abnormalities precede deterioration and stillbirth. However, from 34 to 38 weeks, randomized evidence on optimal delivery timing is lacking. From 38 weeks onward, the balance of neonatal versus fetal risks favors delivery.

Abstract
OBJECTIVES To assess the performance of middle cerebral artery peak systolic velocity (MCA-PSV) and of the expected daily decrease in fetal hemoglobin in determining the timing of serial in-utero transfusions (IUT) in red-cell alloimmunization. METHODS This was a retrospective study of a continuous series of suspected anemic fetuses undergoing IUT between June 2003 and December 2012. Doppler measurement of MCA-PSV and pre- and post-transfusion hemoglobin levels were recorded at the time of the first, second and third IUT. Receiver-operating characteristics (ROC) curves and negative and positive predictive values of MCA-PSV in the prediction of severe fetal anemia were calculated. The daily decrease of fetal hemoglobin (Hb) between IUTs was calculated. Regression analysis was used to assess the correlation between pretransfusion fetal hemoglobin and MCA-PSV, and between observed and expected (by projection of daily decreases) pretransfusion fetal hemoglobin levels. RESULTS One hundred and eleven fetuses required an IUT, of which 96 and 67 received a second and third IUT, respectively. The area under the ROC curve for MCA-PSV in the prediction of severe fetal anemia was not different for each rank of transfusion. The positive predictive value of MCA-PSV decreased from 75.3% at the first IUT, to 46.7% and 48.8% at the second and third IUTs, respectively, while the negative predictive value for a 1.5-MoM threshold remained high (88.9% at the second and 91.7% at the third IUT). The mean daily decrease in hemoglobin following each transfusion was 0.45, 0.35 and 0.32 g/dL, respectively. There was a persistent linear correlation between fetal hemoglobin and MCA-PSV and between observed and expected fetal hemoglobin levels. CONCLUSIONS Both MCA-PSV and projection of daily decrease in hemoglobin are reliable means of diagnosing fetal anemia following previous IUTs. The high negative predictive value of MCA-PSV could allow subsequent IUTs to be postponed in selected cases.

Abstract
α-Thalassemia prevails in Southeast Asia, where α-thalassemia major is a lethal type. Sonography is a helpful and cost-effective screening tool for detecting α-thalassemia major fetuses. The cardiothoracic ratio, placental thickness, and middle cerebral artery peak systolic velocity are most used in clinical practice. These sensitive markers are helpful for evaluation of the hemodynamic status and cardiovascular function of the affected fetuses. They can predict fetal α-thalassemia major and assess the efficacy of treatment noninvasively; therefore, the medical costs as well as the possibility of fetal loss caused by invasive procedures can be reduced. Other potentially useful sonographic markers need further studies, although previous preliminary research suggests their usefulness. This article will review those sonographic markers.

Abstract
Doppler evaluation of the placenta and fetal cardiovascular system is one of the primary surveillance tools in prenatal medicine. By assessing uterine and umbilical arteries, placental development can be documented. This is useful for the prediction of hypertensive maternal disorders and placental dysfunction and fetal growth failure. The umbilical artery flow velocity waveform provides an estimate of villous vascular occlusion in the fetal compartment of the placenta. Middle cerebral artery Doppler is important in studying fetal responses to abnormal oxygenation and fetal anemia. Precordial venous Doppler gives insight into the cardiac effects of many conditions such as fetal growth restriction, twin-twin transfusion syndrome and fetal arrhythmia. Further quantification of these effects requires cardiac Doppler to quantify diastolic and systolic function as well as global myocardial performance. This article reviews important characteristics of arterial and venous Doppler waveform analysis, individual vascular beds and their clinical application in fetal evaluation.
