Given the increase of women with excess weight or obesity and its possible effects on birth weight, the present study aimed to investigate the association between pregestational maternal body mass index (BMI) and birth weight in a birth cohort from Ribeirão Preto, SP, Brazil. This was a prospective study conducted on 1362 mother-child pairs involving singleton births. The women were evaluated using standardized questionnaires during the second trimester of pregnancy and at the time of childbirth. Information about the newborns was obtained from their medical records. The dependent variable was birth weight, categorized as low, adequate, or high. The independent variable was pregestational maternal BMI, categorized as malnutrition, adequate weight, overweight, and obesity. A multinomial regression model was used to estimate the crude and adjusted relative risk (RR) of low and high birth weight. A high frequency of pregestational excess weight (39.6%) was detected and found to be independently associated with high birth weight (RR=2.13, 95%CI: 1.19-3.80 for overweight and RR=3.34, 95%CI: 1.80-6.19 for obese pregnant women). There was no association between pregestational malnutrition and low birth weight (RR=1.70; 95%CI: 0.81-3.55). The present data showed a high rate of women with excess pregestational weight, supporting the hypothesis that pregestational BMI may contribute to high birth weight babies and indicating the need for actions aiming to prevent excessive weight in women at reproductive age.

ABSTRACT Introduction: twin-to-twin transfusion syndrome (TTTS), defined by combination of polyhydramnios-oligohydramnios, is the most prevalent (5%-35%) of the abnormalities due to placental vascular anastomoses and the most lethal (80%-100% mortality) if untreated. Fetoscopic laser ablation of abnormal vasculature using the Solomon technique is the gold standard approach. It consists of interrupting the intertwin blood flow. Objectives: to present our initial experience at the Fetal Surgery Service of the Hospital de Clinicas of the Federal University of Parana (HC-UFPR) and to compare our results with those reported in the literature. Methods: we conducted a retrospective analysis of pregnancies who had undergone laser ablation, assessing data on Quintero's staging, gestational age at diagnosis and at the time of the procedure, placental position, immediate post-procedure survival, and survival after the neonatal period. We then compared these data with the most recent data available in the literature. Results: we analyzed ten TTTS cases. The diagnosis was performed before the 26th week of pregnancy (median 20.8 weeks) and treatment occurred in a median of 9.5 days later. The distribution by the Quintero's staging was of three cases in stage II, five in stage III, and two in stage IV. In 50% of the gestations, at least one of the fetuses survived through the neonatal period. Conclusion: the treatment of TTTS in the HC-UFPR had a positive impact in the survival of the affected fetuses, although the results were worse than the ones reported in the literature, probably due to the delay in referencing the patients to our service, leading to a prolonged interval between diagnosis and treatment.

RESUMO Introdução: a síndrome de transfusão feto-fetal (STFF), definida pela combinação polidrâmnio-oligohidrâmnio, é a mais prevalente (5 a 35%) das anormalidades associadas às anastomoses vasculares placentárias e tem a maior letalidade (80 a 100%) se não tratada. A ablação a laser destes vasos por via fetoscópica com a técnica de Solomon é o tratamento de escolha atual para a interrupção das anastomoses vasculares. Objetivo: apresentar a experiência inicial do Serviço de Cirurgia Fetal do Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR) e comparar nossos resultados com os da literatura. Métodos: foram revisados os prontuários de todas as pacientes submetidas ao procedimento de ablação a laser, sendo analisados os dados referentes ao estadiamento de Quintero, à idade gestacional ao diagnóstico e ao procedimento, à posição placentária, à sobrevida imediata pós-procedimento e sobrevida após o período neonatal. Os dados foram então comparados com os mais recentes disponíveis na literatura. Resultados: dez casos de STFF foram analisados. Todos diagnosticados antes da 26a semana (mediana 20,79) e o intervalo diagnóstico-tratamento teve mediana de 9,5 dias. A distribuição pelo estadiamento de Quintero foi: três casos no estádio II, cinco casos no III e dois casos no IV. Em 50% das gestações pelo menos um dos fetos sobreviveu ao período neonatal. Conclusão: o tratamento da STFF no HC-UFPR impactou positivamente a sobrevida dos fetos acometidos. Entretanto, nossos resultados estão aquém dos reportados na literatura, possivelmente pelo demora no referenciamento das pacientes, com intervalo aumentado entre diagnóstico e tratamento.

INTRODUCTION@#Pregnant women are reported to be at increased risk of severe coronavirus disease 2019 (COVID-19) due to underlying immunosuppression during pregnancy. However, the clinical course of COVID-19 in pregnancy and risk of vertical and horizontal transmission remain relatively unknown. We aim to describe and evaluate outcomes in pregnant women with COVID-19 in Singapore.@*METHODS@#Prospective observational study of 16 pregnant patients admitted for COVID-19 to 4 tertiary hospitals in Singapore. Outcomes included severe disease, pregnancy loss, and vertical and horizontal transmission.@*RESULTS@#Of the 16 patients, 37.5%, 43.8% and 18.7% were infected in the first, second and third trimesters, respectively. Two gravidas aged ≥35 years (12.5%) developed severe pneumonia; one patient (body mass index 32.9kg/m2) required transfer to intensive care. The median duration of acute infection was 19 days; one patient remained reverse transcription polymerase chain reaction (RT-PCR) positive >11 weeks from diagnosis. There were no maternal mortalities. Five pregnancies produced term live-births while 2 spontaneous miscarriages occurred at 11 and 23 weeks. RT-PCR of breast milk and maternal and neonatal samples taken at birth were negative; placenta and cord histology showed non-specific inflammation; and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific immunoglobulins were elevated in paired maternal and umbilical cord blood (n=5).@*CONCLUSION@#The majority of COVID-19 infected pregnant women had mild disease and only 2 women with risk factors (obesity, older age) had severe infection; this represents a slightly higher incidence than observed in age-matched non-pregnant women. Among the women who delivered, there was no definitive evidence of mother-to-child transmission via breast milk or placenta.

Objetivo. Investigar las tasas de trastornos respiratorios y del sueño en los niños cuyas madres se sometieron a una amniocentesis. Materiales y métodos. Se incluyó a niños cuyas madres se sometieron a una amniocentesis en el segundo trimestre (entre las 16 y las 20 semanas) y otros sin procedimiento invasivo (controles). Resultados. Se anallizó a 50 niños en el grupo de amniocentesis y a 47 controles. Hubo mayor incidencia de trastornos del sueño en el grupo de amniocentesis: 30 casos (60 %) frente a 11 controles (23,4 %) (p = 0,001). En el grupo de amniocentesis, 7 niños (14%) tenían asma; en el grupo de referencia, 1 niño (2,1 %) (p = 0,032).Conclusión. Podría haber una asociación entre la amniocentesis en el segundo trimestre, el asma y los trastornos del sueño en los niños. Se requieren estudios futuros y analizar los efectos a largo plazo de las pruebas invasivas.

Objective. The aim was to investigate the rates of respiratory and sleep disturbances in infants whose mothers experienced amniocentesis.Material and methods. Infants whose mothers have undergone midterm amniocentesis (between 16 and 20 weeks) and no invasive procedure (controls) were enrolled.Results. The study analyzed 50 infants whose mothers have undergone amniocentesis (amniocentesis group) and 47 controls. Amniocentesis group had higher incidence of sleep disturbances: 30 cases (60 %), compared with 11 controls (23.4 %) (P = 0.001). In the amniocentesis group there were 7 children (14 %) with asthma, while in the control group, asthma was confirmed in 1 child (2.1 %) (P = 0.032).Conclusion. Our data triggers the hypothesis that associations between midterm amniocentesis, child's asthma and sleep isturbances may exist. These preliminary results reveal the importance of further studies and the need for the analysis of long term effects of invasive testing.

ABSTRACT BACKGROUND: The prevalence of congenital abnormalities in general populations is approximately 3-5%. One of the most important applications of obstetric ultrasound is in detection of fetal structural defects. OBJECTIVE: To assess fetal structural anomalies diagnosed using ultrasound in the three trimesters of pregnancy. DESIGN AND SETTING: Retrospective cohort study at the Mário Palmério University Hospital of the University of Uberaba (Universidade de Uberaba, UNIUBE), from March 2014 to December 2016. METHODS: Ultrasound data at gestational weeks 11-13 + 6, 20-24 and 32-36 were recorded to identify fetal anomalies in each trimester and in the postnatal period. The primary outcome measurements were sensitivity, specificity, positive predictive value and negative predictive value for detection of fetal anomalies and their prevalence. RESULTS: The prevalence of anomalies detected using ultrasound was 2.95% in the prenatal period and 7.24% in the postnatal period. The fetal anomalies most frequently diagnosed using ultrasound in the three trimesters were genitourinary tract anomalies, with a prevalence of 27.8%. Cardiac anomalies were diagnosed more often in the postnatal period, accounting for 51.0% of all cases. High specificity, negative predictive value and accuracy of ultrasound were observed in all three trimesters of pregnancy. CONCLUSION: Ultrasound is safe and has utility for detecting fetal anomalies that are associated with high rates of morbidity and mortality. However, the low sensitivity of ultrasound for detecting fetal anomalies in unselected populations limits its utility for providing reassurance to examiners and to pregnant women with normal results.

ABSTRACT Objective: To evaluate the renal parenchymal area in human fetuses, providing a descriptive analysis on the renal area development by demographic factors during the second gestational trimester. Material and Methods: We analyzed 84 fetuses (44 males and 40 females), for a total of 168 renal units evaluated in terms of longitudinal length, superior pole width, inferior pole width and thickness. Renal volume was calculated by ellipsoid formula. After renal pelvis dissection, length and width were evaluated; as pelvis is free of urine, we considered thickness as 1mm. Renal pelvis volume was also calculated by ellipsoid formula. Renal parenchymal area was assessed by excluding the volume of the renal pelvis from the total renal volume. We performed the statistical analysis by simple linear regression assessing the association between the variables analyzed with the fetal age. Results: Gestational age ranged from 12 to 23 weeks post conception. Mean renal parenchymal area of the right kidney was 666.22mm3 (45.86 to 2375.35mm3) and for the left kidney was 606.76mm3 (68.63 to 2402.57mm3). No statistical difference was observed between the sides (p-value = 0.3456) or genders (p-value = 0.07429). Linear regression between renal parenchymal volume and gestational age was positive for right kidney (y = 133.74x-1479.94 / r2 = 0.4009) and left kidney (y = 149.53x-1761.59 / r2 = 0.4591). Conclusions: The linear regression analysis indicated that renal parenchymal area correlated significantly and positively with fetal age, weight and crown-rump length with no statistical differences between gender or laterality. These growth curves provide a reference for functional volume of the kidney during fetal period.

OBJECTIVE@#To analyze the application of three-dimensional power Doppler sonography (3-DPDS) in evaluation of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in second-trimester fetus.@*METHODS@#Three-dimensional volume probe was used to collect the 3-DPDS blood flow images in 50 normal fetuses of 22-24 weeks and 50 fetuses of 30-32 weeks, respectively. The characteristics of three-dimensional ultrasound were analyzed. The clinical and imaging data of 4 fetuses of 26-32 weeks with midgut volvulus were analyzed retrospectively.@*RESULTS@#The display rates of SMA and SMV were 93%in normal group by 3-DPDS and those in volvulus group were 4/4 and 3/4, respectively. The SMV trunk was parallel to and on the right side of the SMA in the normal group, while 3 cases in volvulus group showed the characteristic relationship of SMV swirling around SMA.@*CONCLUSIONS@#3-DPDS can be used to observe the spatial relationship of SMA and SMV visually in fetus during the second trimester and is of value to diagnose and predict the outcome of midgut volvulus.

PURPOSE: To determine whether maternal attitude toward sex during pregnancy and health-related quality of life could influence sexual function of pregnant women. METHODS: In this study, 138 second and third trimester pregnant women completed self-report questionnaires during their visits to women's hospitals or community health centers to assess their general characteristics, attitude toward sex during pregnancy (PIES-M), health-related quality of life (EQ-5D), and sexual function (FSFI-6K). Multiple regression analysis was performed to test the research model with SPSS version 23. RESULTS: Pregnant women who had discontinued their sexual life after recognizing their pregnancy accounted for 27.5% of women questioned. The average sexual function score of pregnant women was higher in the second trimester than the third trimester. Attitude toward sex during pregnancy (β=−.38, p< .001), maintaining sexual life (β=.20, p=.028), health-related quality of life (β=.18, p=.030), and adverse symptoms during sex (β=.18, p=.042) were determinants of sexual function during pregnancy. CONCLUSION: Nurses in antenatal care units need to help pregnant women maintain a positive attitude toward sexual activity during pregnancy and manage their health-related quality of life to maintain their sexual life during pregnancy.

PURPOSE: The objective of this study was to investigate the prevalence of antenatal depression in pregnant women and its influencing factors. METHODS: With a cross-sectional survey design, a total of 396 pregnant women were recruited from a local obstetrics and gynecology clinic. Measurements included antenatal depression, perceived stress, predictors of depression during pregnancy, and demographic and obstetric characteristics. RESULTS: Mean antenatal depression score was 8.20 (standard deviation=4.95) out of 30, falling into its normal range. However, the prevalence of antenatal depression was 35.9% when cut-point of 9/10 was used. The prevalence of antenatal depression among women in the first trimester was 31.4%. It was slightly increased to 34.9% in the second trimester but significantly increased to 40.5% in the third trimester. In multiple logistic regression analysis, experiencing prenatal anxiety (odds ratio [OR], 4.16), having no job (OR, 2.90), lower self-esteem (OR, 1.62), and higher perceived stress (OR, 1.32) were significant factors influencing antenatal depression. CONCLUSION: Negative feeling such as feeling anxious, lower self-esteem, and higher perceived stress during pregnancy are key factors affecting antenatal depression. Thus, antenatal nursing intervention focusing on pregnant women's feeling upon their job status is necessary to improve their antenatal psychological well-being.

OBJECTIVE@#To explore the mechanism and duration of false positive results of non-invasive prenatal testing (NIPT) caused by vanishing twins.@*METHODS@#To detect the variation of cell-free fetal DNA fraction before and after the fetal death and explore its influence on the results of NIPT at different gestational weeks. Prenatal diagnosis was also carried out on amniotic fluid sample derived from the survivor twin. After birth, the two placentas and papyraceous fetus were obtained to ascertain the definitive genetic diagnosis and pathological changes through fluorescence in situ hybridization, fluorescence quantitative PCR and histopathological examination. Eight cases of vanishing twins leading to discordant NIPT results were reviewed for determining the duration of this influence.@*RESULTS@#The vanishing twin has led to immediate flooding of cfDNA into the maternal plasma due to necrotic cytotrophoblasts, which in turn caused increased release of fetal DNA in a short time. However, this did not change the NIPT result for a period of time. The tissue and chorionic villi of perished fetus presented extensive degenerative necrosis.@*CONCLUSION@#The false positive NIPT result caused by vanishing twins may be attributed to continuous release of DNA fragments into the maternal plasma by the fetuses. The influence of the vanished fetuses, which may lead to discordant NIPT results, can last for at least 7-8 weeks but no more than 12-14 weeks during the first and second trimester.

The visual system of women changes during pregnancy. Few reports have addressed the effects of pregnancy on color vision. We aimed to compare the color vision of women in the first, second, and third trimesters of pregnancy. Fifty women were divided into first (n=10), second (n=10), third trimester pregnancy groups (n=10), and non-pregnant group (n=20). We used the Farnsworth D15 and Lanthony desaturated D15 (D15d) tests. The hue ordering quantified the amount of error (C-index) and the chromatic selectivity of the errors (S-index). Bland-Altman analysis was applied to the hue ordering data. No difference was found for Farnsworth D15 test results obtained from the pregnant groups and the non-pregnant group (P<0.0083). For the Lanthony D15 desaturated test, the third trimester pregnant group had higher C-index and S-index than non-pregnant women and first-trimester pregnant women (P<0.0083). The Bland-Altman analysis showed that the limits of agreement increased as pregnancy advanced, and the errors were biased to the D15d test. In this study, color vision was impaired during pregnancy. Color vision evaluation could be used as an indicator of the functional status of the central vision during pregnancy.

The congenital diaphragmatic hernia (CDH) is a congenital defect of the formation and /or closure of the diaphragm that permits the herniation of abdominal contents into the thorax. It occurs when the diaphragmatic muscle fails to close during the prenatal development, and the contain of the abdomen migrate into the chest through this hole. When the abdominal organs are in the chest, there is limited room for the lungs to grow. This prevents the lungs for developing normally, resulting in pulmonary hypoplasia (or underdeveloped lungs). This can cause reduced blood flow to the lungs and pulmonary hypertension, as well as gastrointestinal reflux, feeding disorders and developmental delays. CDH can occur on the left side, right side or, very rarely, on both sides, and it can be life-threatening. The etiology is usually unknown. The incidence of CDH may be as high as 1 in 2000 to 1 in 5000 newborns alive. The sex relationship male/female is 1:1.8. Because of associated persistent pulmonary hypertension of the newborn and pulmonary hypoplasia, medical therapy in patients with CDH is directed toward optimizing oxygenation while avoiding definitive therapy. No time for repair of CDH is ideal, but it is suggested that the opportunity is 24-48 hours after birth to achieve pulmonary development. The key to survival lies in prompt diagnosis and treatment. Over the past two decades antenatal diagnosis rates have increased the knowledge of the pathophysiology of CDH and has become better understand with advances in clinical care including prenatal surgery, with a reported mortality of almost 35 % in live-born patients and a higher mortality when in utero deaths are conected. All these considerations are described in the article, with special reference to pre and post-natal treatment, complications management, diagnosis and prognosis

ABSTRACT Introduction: Paraganglioma is an extremely rare catecholamine-producing tumor during pregnancy. Paraganglioma carries high risks of fetal and maternal mortality during pregnancy. We report a pregnant woman with paraganglioma in the second trimester. Case Description: A 24-year-old pregnant woman presented with severe hypertension in the 17th week of gestation. Hormonal examination and Magnetic Resonance Imaging (MRI) confirmed the diagnosis of extra adrenal pheochromocytoma (paraganglioma). She underwent laparoscopic tumor excision successfully. Conclusions: A high index of suspicion is needed to diagnose paraganglioma in a pregnant patient with hypertension. Laparoscopic tumor removal for paraganglioma seems to be a feasible and safe procedure during pregnancy.

La vaginosis bacteriana (VB) es un síndrome producido por el desbalance de la microbiota vaginal normal, frecuente en mujeres en edad fértil, incluyendo embarazadas (ME). Los objetivos de este trabajo fueron conocer la prevalencia de VB en el segundo trimestre de embarazo en la población estudiada y su impacto sobre la producción de partos prematuros (PP) y/o de bajo peso al nacer (BPN). Se realizó un estudio retrospectivo, comparativo, de casos y controles, de 315 ME con y sin vaginosis en el segundo trimestre de embarazo entre 2009 y 2016. Se consideraron “casos” a aquellas mujeres afectadas por VB (estadio IV) y “controles” a las que exhibían una microbiota habitual (estadio I). El 20% de las ME presentaron VB (estadio IV). Se registraron 16 BPN (11 entre los 62 casos y 5 entre los 120 controles) (p=0,025). En 16 oportunidades el parto fue prematuro (10 entre los casos y 6 entre los controles) (p=0,007) En total, las dificultades en el parto fueron significativamente más numerosas entre los casos que entre los controles (p=0,009). Al menos en la población estudiada la presencia de vaginosis en el segundo trimestre de las ME estuvo significativamente asociada con PP y/o BPN.

Bacterial vaginosis (BV) is a syndrome produced by the imbalance of the normal vaginal microbiota, common in women of childbearing age including pregnant women (PW). The objectives of this study were to know the prevalence of BV in the second trimester of pregnancy in the population studied and its impact on the production of premature births (PB) and/or low birth weight infants (LBWI). A retrospective, comparative study of cases and controls of 315 PW with and without vaginosis was carried out in the second trimester of pregnancy between 2009 and 2016. Those cases affected by BV (stage IV) were considered “cases”, and “controls” those that exhibited a habitual microbiota (stage I). Twenty percent of PW presented VB (stage IV) and 16 LBWI were recorded (11 among 62 cases and 5 among 120 controls) (p=0.025). On 16 occasions, labour was premature (10 among cases and 6 among controls) (p=0.007). In total, the difficulties in delivery were significantly more numerous among the cases than among the controls (p=0.009), at least in the population studied the presence of vaginosis in the second trimester of the ME was significantly associated with PB delivery and/or LBWI.

Abstract Objectives: to verify the contribution of polymorphisms rs1800469 and rs1800468 of the TGF-β1 gene and the risk factors for the pre-eclampsia development. Methods: this is a case-control study with 257 women from the Uberaba region of Minas Gerais were selected, 88 of them were in the pre-eclampsia group and 169 in the control group. Genotyping was performed by allelic discrimination using the real-time PCR technique. The odds ratio and the 95% confidence interval were used to evaluate the probability of the polymorphisms studied contributing for the pre-eclampsia development. The logistic regression analysis was performed to evaluate the relation among family recurrence, smoking, primiparity and the presence of polymorphic alleles and susceptibility of preeclampsia. Results: no association was found between polymorphisms rs1800469 and rs1800468 of the TGF-β1 gene and pre-eclampsia. The logistic regression analysis was statistically significant for family recurrence, showing that women with a family history of pre-eclampsia and primiparity are at an increased risk of developing the disease. Conclusions: no association was found between polymorphisms rs1800469 and rs1800468 of the TGF-β1 and pre-eclampsia gene. Factors such as family history and primiparity were associated to the risk of developing pre-eclampsia.

Métodos: trata-se de um estudo caso-controle, onde foram selecionadas 257 mulheres, da região de Uberaba, Minas Gerais, sendo 88 do grupo PE e 169 controles. A genotipagem foi realizada por discriminação alélica através da técnica de PCR em tempo real. Odds ratio e o intervalo de confiança de 95% foram usados para avaliar a probabilidade dos polimorfismos estudados contribuírem com o desenvolvimento de PE. A análise de regressão logística foi realizada para avaliar a relação entre recorrência familiar, tabagismo, primiparidade e presença dos alelos polimórficos e a suscetibilidade a PE. Resultados: não foi observada associação entre os polimorfismos rs1800469 e rs1800468 do gene TGF-β1 e PE. A análise de regressão logística foi estatisticamente significativa para recorrência familiar, mostrando que mulheres com histórico familiar de PE e mulheres primigestas possuem risco aumentado de desenvolver a doença. Conclusões: não foi encontrada associação entre os polimorfismos rs1800469 e rs1800468 do gene TGF-β1 e PE. Fatores como histórico familiar e primiparidade foram associados com o risco de desenvolvimento de PE.

BACKGROUND/AIMS: Maternal thyroid dysfunction has been associated with adverse pregnancy outcomes. The purpose of our study was to establish trimester-specific reference intervals for thyroid hormones in pregnant women in Korea, where iodine intake is more than adequate and to examine pregnancy and perinatal outcomes in their offspring. METHODS: Among 459 healthy pregnant women who were screened, we enrolled 417 subjects who had negative results for thyroid autoantibodies. Serum thyroid stimulating hormone (TSH) and free thyroxine were measured using an immunoradiometric assay. Urine iodine concentration was measured using inductively coupled plasma-mass spectrometry in 275 women. Reference ranges of thyroid hormones were determined according to the guidelines of the National Academy of Clinical Biochemistry. Pregnancy and perinatal outcomes were compared according to maternal thyroid function. RESULTS: The reference ranges of serum TSH were 0.03 to 4.24 mIU/L in the first trimester, 0.13 to 4.84 mIU/L in the second trimester, and 0.30 to 5.57 mIU/L in the third trimester. Pregnancy and perinatal outcomes did not vary in mothers with subtle changes in thyroid function. CONCLUSIONS: Trimester-specific thyroid hormone reference intervals in Korean pregnant women differ from those of other countries with different iodine nutrition status and ethnicity. The establishment of population-based, reliable trimester-specific reference intervals is critical for the interpretation of thyroid function in pregnant women to avoid unnecessary tests and treatments.

Although gravid uterine incarceration is typically diagnosed during the early second trimester, we encountered two unusual cases in early pregnancy. A 34-year-old multiparous woman with adenomyosis presented at 7 + 2 weeks of gestation with increased urinary frequency and a sensation of incomplete bladder emptying. The uterine incarceration was successfully reduced by manual reduction and pessary insertion, and she delivered a normal infant at term. In the second case, a 31-year-old nulliparous woman with a large myoma complained of dysuria, acute urinary retention, and intense back pain at 6 weeks of gestation. Manual reduction was successful in the knee-chest position. Subsequent pessary insertion failed; however, a slight reduction in pain was achieved. After a week, the fetus spontaneously aborted. In summary, gravid uterine incarceration is a rare but potentially fatal condition for the fetus, and a suspicion of this condition in patients with urinary symptoms, especially urinary retention and pelvic pain, is important in the early gestation period.

Cerebral venous sinus thrombosis (CVST) is a rare condition in early pregnancy. A 22-year-old Chinese woman at 10 weeks of pregnancy requested induced abortion and was diagnosed as CVST for a severe headache accompanying with nausea and vomiting. The patient was treated successfully with anticoagulation, followed by amniocentesis, and finally succeeded in induction of labor safely. The diagnosis, treatment and prognosis for this rare condition are discussed in this paper.
