Twin anemia-polycythemia sequence (TAPS) is characterized by a wide discrepancy of hemoglobin between two monochorionic fetuses without sign of twin oligo-polyhydramnios sequence. A primiparous woman with monochorionic diamniotic twin transferred for preterm labor. Ultrasonographic evaluation at 32+3 weeks of gestation revealed increased middle cerebral artery-peak systolic velocity (77.4 cm/se...

Hypoplastic left heart syndrome is a congenital disease which accounts for 8% of all defects. Twin pregnancies have significantly higher risk structural than singleton ones, however the concordance rate has been found to be relatively low, even in monochorionic pregnancies. We describe here favorable evolution monochorionic, diamniotic, twin pregnancy both fetuses were diagnosed with hypoplasti...

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...

INTRODUCTION This study investigates patterns of intertwin size discordance in dichorionic diamniotic (DCDA) and monochorionic diamniotic (MCDA) twin pregnancies. MATERIAL AND METHODS Ultrasound measurements of twin pregnancies, from 14 weeks to term, were collected by 9 hospitals over a 10-year period. This analysis considers the modelled and observed levels of discordance in abdominal circu...

A 41-year-old Saudi woman, gravida 7, para 5, aborta 1 with sickle cell disease at week 12 of gestation of diamniotic dichorionic twin pregnancy was admitted with fever. Blood cultures grew Listeria monocytogenes. She was treated with intravenous ampicillin and had death of one of the fetuses after 10 days. An ultrasound at 19 weeks of gestation showed a normal intrauterine gestation and the pr...

Maternal mirror syndrome is a rare consequence of fetal hydrops. By convention, delivery is recommended in pregnancies complicated by mirror syndrome due to grave fetal prognosis. We describe a case of a dichorionic, diamniotic twin gestation complicated by hydrops fetalis of twin B. The patient declined selective feticide. Two weeks later, intrauterine fetal demise of fetus B was diagnosed and...

Twin to twin transfusion syndrome (TTTS) is a common complication of monochorionic twin gestations. If untreated, this condition carries a very high mortality rate for both twins. The therapeutic options available today are still rather limited. Therapeutic amniocentesis (amnioreduction) of the recipient twin's amniotic fluid has been shown to be effective in equalising pressures between the tw...
