Dias T, Ladd S, Mahsud-Dornan S, Bhide A, Papageorghiou AT, Thilaganathan B. Systematic labeling of twin pregnancies on ultrasound. Ultrasound Obstet Gynecol 2011; 38: 130–33 Sometimes a paper comes along with the simple answer to a common question so that the reader has a “Why didn’t I think of that?” moment. This is one of those. We have all come across the potential errors in labeling twins ...

It is well established that the death of one fetus in a monochorionic twin pregnancy places the surviving twin at significant risk for neuro-developmental delay or death. Although the early 1st trimester "vanishing twin" has not traditionally been considered a major risk, the precise gestational threshold beyond which a surviving twin is at risk remains uncertain. Most experts recommend serial ...

UNLABELLED INTRODUCTION. Pentalogy of Cantrell is a very rare congenital multiple malformation with the poor outcome. Syndrome included the following pentad: abdominal wall defect, a defect of the lower sternum, anterior diaphragm defect, ectopia cordis, as well as a variety of intracardiac anomalies. CASE REPORT In the fifteenth week of the twin pregnancy, ultrasound examination showed multi...

intra-uterine pregnancy of 19 weeks gestation. All along the size of the uterus was bigger than the period of amenorrhoea suggested. The foetal movements were first felt in the second week of January 1971 at 18 weeks gestation (uterine size 22 weeks). She developed mild hypertension on 2 April 1971 and was admitted for rest. An X-ray of the abdomen then revealed a twin pregnancy. The following ...

Retrospective assessment of maternal smoking or substance use during pregnancy is sometimes unavoidable. The unusually close relationship of twin sister pairs permits comparison of self-report data versus co-twin informant data on substance use during pregnancy. Information about smoking during pregnancy has been gathered from a series of mothers from an Australian volunteer twin panel (576 wom...

A chromosomal abnormality in one of the fetuses of a monozygotic twin pregnancy is a rare phenomenon. In the prenatal unit of our cytogenetics laboratory we have recently come across two such heterokaryotypic twin pregnancies. In both cases ultrasound abnormalities were detected in one fetus of each twin pair. Chromosomal analysis showed that one twin pregnancy was discordant for trisomy 21 and...

Decreased fetal movement (DFM) perceived by pregnant women sometimes indicates imminent fetal jeopardy. It is unknown whether this also holds true for twin pregnancy. A 27-year-old primiparous woman with monochorionic diamniotic (MD) pregnancy had a slight difference of amniotic fluid volume at 31(2/7) weeks of gestation. DFM only in one twin at 31(4/7) weeks of gestation prompted her to receiv...

The risk of structural heart disease is significantly higher in twin pregnancies than in singleton pregnancies, but the concordance rate has been found to be relatively low, even in monochorionic pregnancies. This is the first report of a monochorionic twin pregnancy concordant for hypoplastic left heart syndrome (HLHS), the diagnosis having been made by fetal echocardiography at 15 weeks' gest...

It has recently been suggested that the measure of success of assisted reproductive technologies (ART) should be the birth of a singleton baby, whereas a twin pregnancy should be considered as a complication. Although the maternal and neonatal complications in twin pregnancies are significantly higher than those in singleton pregnancies, the classification of a twin pregnancy as a complication ...
