Hypertensive disorders in pregnancy are major causes of maternal mortality and morbidity. Although the combined risk assessments history, blood pressure, uterine artery Doppler, serum marker seem to be highly predictive development hypertensive disorders, this method is a little complicated performed on many low-risk pregnant women. The aim study evaluate use characteristics, physical findings early second trimester, as factors disorders. This retrospective cohort undertaken single tertiary...

Methods: This a retrospective single-center cohort 2143 singleton pregnant women. association HNBP, ranging from 130/85 139/89 mmHg between 14 19 weeks gestation, with development assessed by multivariable logistic regression analyses. Results: In 2102...

The appropriate effectiveness of inter-twin amniotic fluid discordance (AFD) in the early second trimester for prediction severe twin-twin transfusion syndrome (TTTS) was evaluated.The largest AFD between 16 and 18 weeks' gestation analyzed correlation with TTTS development defined by polyhydramnios a maximum vertical pocket (MVP) ≥8 cm combined oligohydramnios MVP ≤2 using receiver operating characteristics curve. All pregnancies were stratified according to an cutoff, perinatal outcomes...

Abstract Aim To examine the intrapartum cesarean delivery rate following failure of induction labor (IOL) as well risk factors associated with failed IOL among nulliparous women advanced maternal age (AMA). Methods This was a retrospective cohort study conducted at single perinatal care center. We retrospectively reviewed medical records AMA (aged 35 years or older) singleton vertex pregnancy who underwent term. Data regarding baseline characteristics and course, including complications...

To elucidate the incidence of and risk factors for severe hypertensive disorders (HD) related maternal complications in uncomplicated twin pregnancies that reached 36 weeks' gestation.We conducted a prospective cohort study delivered after gestation. Cases twin-twin transfusion syndrome, anemia-polycythemia sequence, malformed fetuses, monoamniotic twins, selective reduction, fetal therapy HD or death before 35 gestation were excluded. The study's primary outcome was complications, including...

Abstract Aim To investigate the prevalence of qualitative abnormal umbilical artery Doppler waveforms (Abnormal UA) during early second trimester and subsequent variation in monochorionic diamniotic (MCDA) twin pregnancies. Methods This prospective cohort study included 153 MCDA Pulsed examinations for UA were performed at four points, including free‐loop (FL) near placental cord insertion site (CI) each UA, between 16 17 weeks' gestation. Cases classified into positive diastolic (Type I),...

Abstract Aim This study aimed to evaluate the incidence of unexpected critical complications (UCC) in monochorionic diamniotic (MCDA) twin pregnancies according ultrasonographic scan interval. Methods retrospective single‐center cohort study, conducted between January 2005 and April 2015, investigated UCC patients with MCDA undergoing weekly ultrasound (Group A) those biweekly B). We also examined predictable Results Of all 385 cases, total was 20 (5.2%), including 14 cases twin‐twin...

Here, we report an extremely rare case of trichoepithelioma (TE)—a benign epithelial tumor originating from the outer root sheath a hair follicle—arising in ovarian mature cystic teratoma (MCT) with fluorodeoxyglucose-positron emission tomography (FDG-PET) findings. A 48-year-old Japanese woman presented to our hospital for her annual follow-up adenomyosis. Ultrasonography and magnetic resonance imaging revealed left irregular-shaped septum, which was suspicious malignancy. However, marker...

The aim of this study was to evaluate the relevance abdominal circumference (AC) discordance and sIUGR in monochorionic diamniotic (MCDA) twins. This a retrospective MCDA twins referred our hospital before 18 weeks gestation. We assessed discordant rate (DR; %) AC from 14 17 defined as estimated body weight < −1.5SD (standard measurement by Japan Society Ultrasonics Medicine). Exclusion criteria were TTTS, both FGR, fetal abnormality, unavailability data. Cases classified into three types...

The aim of this study is to evaluate the prenatal outcomes fetus complicated with fetal growth restriction (FGR) in late 2nd trimester, and managed expectantly during pregnancy delivery. This a prospective observational study. A total 880 scans were performed on fetuses trimester from April 2009 2010. 741 neonate apply inclusion criteria was consecutively observed born our institution. Inclusion as follows: (1) singleton pregnancy; (2) Absence congenital malformations (including...

In high risk pregnancies, uterine artery Doppler flow examination have been reported valuable to predict of pre-eclampsia (PE) and fetal growth restriction (FGR), however, it has scarcely evaluated in low populations. The aim this study is analyze the association with abnormal (UtA) adverse pregnancy outcomes This a prospective observational study. A total 880 scans were performed late 2nd trimester from 2009 2010. Two hundred sixty-three women met inclusion criteria as follows: (1)...

Uterine pseudoaneurysm is a potentially fatal complication that can occur after non-traumatic delivery/abortion and surgical procedures such as cesarean section myomectomy. We encountered case of hysteroscopic myomectomy, necessitating hysterectomy due to massive hemorrhage. A 40-year-old woman was referred our institution with hypermenorrhea caused by submucous leiomyoma. The leiomyoma resected surgery, which revealed FIGO type 3 transvaginal ultrasonography at the routine follow-up visit...

目的:低リスクの初産婦において,妊娠中期子宮動脈血流波形異常の頻度を明らかにし,血流波形異常とPIH発症,Light for date(LFD)児出生の関連を検討する.対象と方法:低リスクの単胎初産婦で,2009年4月から2010年4月末に妊娠中期子宮動脈血流波形測定が行われ,当科で分娩を取り扱った137例を対象として,子宮動脈血流波形とPIHの発症,LFD児出生との関連を調べた.妊娠初期リスクスコアで0‐1点のものを低リスクとし,子宮動脈のPI値はMerz Eの基準値を用いて両側の平均値が95パーセンタイル以上を高値とした.結果と考察:子宮動脈血流波形PI値上昇3例中,PIHの発症例はなく(p=0.978),2例にLFD児を認めた(p=0.020).多変量ロジスティック解析では,LFD児出生に関連する因子としてPI値上昇が抽出された.PIH発症に関しては有意な項目はえられなかった.結論:低リスク単胎初産婦に対しても,妊娠中期の子宮動脈血流測定での血流波形異常の出現は,LFD児出生予測に関して有用である可能性がある.
