- Fetal thrombotic vasculopathy: A case report and literature review(2016) PELEJA, Ana Berquo; MARTINELLI, Silvio; RIBEIRO, Renata Lopes; BITTAR, Roberto Eduardo; SCHULTZ, Regina; FRANCISCO, Rossana Pulcineli VieiraIntroduction: Fetal thrombotic vasculopathy is a recently described placental alteration with varying degrees of involvement and often associated with adverse perinatal outcomes. The diagnosis is made histologically and therefore is postnatal, which makes it a challenge in clinical practice. Method: Case report and review of literature on the subject. Results: The present case refers to a pregnant woman presenting fetal growth restriction, with poor obstetrical past, and sent late to our service. Even with weekly assessments of fetal vitality (fetal biophysical profile and Doppler velocimetry) and prenatal care, the patient progressed with fetal death at 36 weeks and 1 day. There was no association with inherited and acquired thrombophilia. Pathological examination of the placenta revealed fetal thrombotic vasculopathy. Conclusion: The fetal thrombotic vasculopathy may be associated with adverse perinatal outcomes including fetal death, but much remains to be studied regarding its pathogenesis. Diagnosis during pregnancy is not possible and there is still no proven treatment for this condition. Future studies are needed so that strategies can be developed to minimize the impact of fetal thrombotic vasculopathy.

M. L. de; BRIZOT, Maria L.; LIAO, Adolfo W.; BITTAR, Roberto E.; FRANCISCO, Rossana P. V.; ZUGAIB, MarceloIntroductionA previous study indicated that progesterone reduces the mean uterine contraction frequency in singleton pregnancy at high risk for preterm birth. The aim of this study was to investigate the effect of vaginal progesterone on the frequency of uterine contractions in twin pregnancies. Material and methodsThis was a secondary analysis of a randomized, double-blind, placebo-controlled trial of twin pregnancies exposed to vaginal progesterone or placebo. Naturally conceived twin pregnancies with no prior history of preterm delivery, asymptomatic regarding preterm labor, who had undergone uterine contraction frequency monitoring from 24 to 34 weeks and 6 days were included in the study. Comparison of the mean frequency of uterine contractions between the treatment groups was performed. We also examined the influence of cervical length and chorionicity on the mean frequency of uterine contractions according to the group. ResultsThe final analysis included 166 women in the progesterone and 170 in the placebo group. The baseline characteristics were similar in the two groups. Overall, no difference in the mean frequency of uterine contractions (p = 0.91) was observed between the progesterone (2.54 3.19) and placebo (2.56 +/- 3.59) groups. Also, no difference in the mean frequency of uterine contractions was observed between the groups in each week between 24 and 34 weeks and 6 days of gestation. Cervical length and chorionicity did not influence the frequency of contractions according to the progesterone or placebo treatment. ConclusionsOverall, progesterone does not influence the frequency of uterine contractions in twin pregnancies.
