- Is Doppler ultrasound useful for evaluating gestational trophoblastic disease?(2015) LIN, Lawrence H.; BERNARDES, Lisandra S.; HASE, Eliane A.; FUSHIDA, Koji; FRANCISCO, Rossana P. V.Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblastic neoplasia. The PubMed/Medline, Web of Science, Cochrane and LILACS databases were searched for articles published in English until 2014 using the following keywords: ""Gestational trophoblastic disease AND Ultrasonography, Doppler."" Twenty-eight articles met the inclusion criteria and were separated into the 4 following groups according to the aim of the study. (1) Doppler ultrasound does not seem to be capable of differentiating partial from complete moles, but it might be useful when evaluating pregnancies in which a complete mole coexists with a normal fetus. (2) There is controversy in the role of uterine artery Doppler velocimetry in the prediction of development of gestational trophoblastic neoplasia. (3) Doppler ultrasound is a useful tool in the diagnosis of gestational trophoblastic neoplasia because abnormal myometrial vascularization and lower uterine artery Doppler indices seem to be correlated with invasive disease. (4) Lower uterine artery Doppler indices in the diagnosis of gestational trophoblastic neoplasia are associated with methotrexate resistance and might play a role in prognosis. CONCLUSION: Several studies support the importance of Doppler ultrasound in the management of patients with gestational trophoblastic neoplasia, particularly the role of Doppler velocimetry in the prediction of trophoblastic neoplasia and the chemoresistance of trophoblastic tumors. Doppler findings should be used as ancillary tools, along with human chorionic gonadotropin assessment, in the diagnosis of gestational trophoblastic neoplasia.
- Fetal growth according to different reference ranges in twin pregnancies with placental insufficiency(2015) NAKANO, Julianny Cavalheiro Nery; LIAO, Adolfo Wenjaw; BRIZOT, Maria de Lourdes; MIYADAHIRA, Mariana; FRANCISCO, Rossana Pulcineli Vieira; ZUGAIB, MarceloThe aim of this study was to compare different fetal growth curves in twin pregnancies with severe placental insufficiency. A retrospective cross-sectional analysis of 47 twin pregnancies with absent or reverse end diastolic flow in the umbilical artery of one fetus was performed. Pregnancies with major fetal abnormalities, twin-twin transfusion or three or more fetuses were not included. The estimated fetal weight zeta-scores were calculated for both fetuses (abnormal Doppler and co-twin) according to the following criteria: Hadlock, Liao and Araujo. The abdominal circumference zeta-scores were calculated according to Hadlock, Liao, Araujo, Ong and Stirrup. The mean estimates of the zeta-score values were calculated using generalized estimating equation regression analysis. The mean gestational age at inclusion was 27.4 +/- 4.7 weeks. The fetal sex and the interaction Doppler findings x criteria correlated significantly with the zeta-score values (p<0.001 for both variables). The estimated fetal weight mean zeta-scores (standard error) according to each criteria were as follows: Hadlock - abnormal Doppler: -2.98 (0.18), co-twin: -1.16 (0.15); Liao -abnormal Doppler: -2.89 (0.24), co-twin: -0.58 (0.19); and Araujo - abnormal Doppler: -3.05 (0.29), co-twin: -0.75 (0.18). Values for abdominal circumference were as follows: Hadlock -abnormal Doppler: -3.14 (0.26), co-twin: -1.13 (0.19); Liao -abnormal Doppler: -2.63 (0.27), co-twin: -0.42 (0.19); Araujo abnormal Doppler: -2.44 (0.22), co-twin: -0.71 (0.14); Ong -abnormal Doppler: -3.36 (0.34), co-twin: -1.48 (0.23); and Stirrup AD - -2.36 (0.14), co-twin: -1.18 (0.10). Sex-and plurality-specific charts should be used in the evaluation of fetal growth in twin pregnancies with placental insufficiency.
