Twin reversed arterial perfusion sequence (TRAP), refers to a rare, unique complication of mono-chorionic twin pregnancy in which a twin with an absent or a nonfunctioning heart (acardiac twin) is perfused by its co-twin (pump twin) via placental arterial anastomoses. The acardiac twin usually has a poorly developed heart, upper body and head. The pump twin is at risk of heart failure and probl...

The present study aimed to determine the effect of administrating prostaglandin F2α (PGF2α) and GnRH at the time of artificial insemination (AI) on the pregnancy per artificial insemination (P/AI) and the pregnancy survival rate of dairy cows. A number of 830 lactating Holstein cows were randomly divided into four groups. Cows in group 1 (n=200) treated with 150 µg d-cloprostenol. In group 2 (n...

Results First case of TRAP sequence was diagnosed at 8 weeks of gestation and controlled at 10 weeks using transvaginal 3D/4D ultrasound. 3D/4D ultrasound imaging showed a monovhorionic-monoamniotic twin pregnancy with nornal morpology and growth of the first twin and growth restriction of the second twin, with abnormal cephalic pole (acrania), no presence of cardiac activity and presence of re...

Twin-reversed arterial perfusion sequence is a rare complication of monochorionic twin pregnancy in which an anomalous acardiac fetus is hemodynamically dependent on its structurally normal "pump" twin. Early diagnosis is essential for improving perinatal prognosis for the normal twin. In this case report we present a case of TRAP sequence with immense acardiac twin with favorable outcome, emph...

Introduction: Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy. Aim: To evaluate the maternal and fetal complications in twin pregnancies. Materials and methods: 300 Twin Pregnancies were studied over a period of 16 months from 200607 to evaluate complications to the mother and both fetuses. Data obtained at the time of deliver...

AIM To evaluate the prevalence of increased nuchal translucency (NT) in multiple pregnancies and its relation to fetal karyotype and pregnancy outcome. METHODS We measured fetal nuchal translucency (NT) in 6,338 women pregnant from 10+3 to 13+6 weeks by ultrasound and evaluated the prevalence of NT=95th centile in 115 multiple pregnancies, including 100 pairs of twins (70 dichorionic and 30 m...

Ectopic pregnancy is an extrauterine pregnancy, and 98% of which occur in the fallopian tube. The incidence of twin tubal pregnancy is rare but is increasing due to assisted reproductive technology. Spontaneous unilateral twin tubal pregnancy is extremely rare, and only a small number of case reports have been made. We herein report a rare case of spontaneous unilateral twin tubal pregnancy wit...

We examined the prevalence of specific perinatal complications of monochorionic-diamniotic twin pregnancies in cases without any abnormal findings until the second trimester of pregnancy. This was a retrospective cohort study performed at a tertiary perinatal center in Tokyo, Japan. There were 88 cases of uncomplicated monochorionic-diamniotic twin pregnancies at 28 weeks of gestation. In five ...

The single stillbirth long-term intrauterine retention in dichorionic twin pregnancy is rarely reported. Also, the birth of a fetus is followed in most cases by immediate expulsion of the second twin. We hereby present an unusual case of asynchronous delivery of dichorionic twins, associating discordance for major and minor anomaly. The intrauterine death of the twin A, presenting a large sacro...
