Twin-to-twin transfusion syndrome (TTTS) has been related to unbalanced unidirectional arteriovenous anastomoses in the placenta of monochorionic diamniotic (DiMo) twin gestations. As maternal malnutrition accounting for hypoproteinemia and anemia has been detected in severe cases of TTTS, the purpose of this study was to evaluate the impact of early diet ...

Standard artificial insemination (AI) using a speculum in dairy goats does not result in acceptable fertility rates in nulliparous does. An explanation might be the difficulties to pass the cervical canal in nulliparous females with the insemination gun, increasing the time needed for semen deposition. Nulliparous Alpine dairy goats were ...

The risk of perinatal morbidity and mortality in twins is 3-7 times higher than in singletons. In comparison to dichorionic twins, monochorionic twins are at increased risk for perinatal mortality and serious morbidity. In both type of twins growth discordance can occur. Discordant growth of dichorionic twins could be due ...

Twin reversed arterial perfusion (TRAP) sequence, also known as acardiac malformation, is a rare complication unique to monozygotic multiple gestations. It occurs in approximately 1 per 35,000 pregnancies and in 0.3% of all monozygotic twin gestations. The malformation is characterized by the lack of a well-defined cardiac structure in one ...

Embryo reduction of unilateral twin vesicles is normally successful before fixation of the vesicles. After fixation, however, it becomes a challenge, and the later in the gestation period that the reduction is performed, the greater the challenge. One therapy to reduce a twin into a singleton pregnancy is the transvaginal ...

Antenatal sonographic diagnosis of twin-twin transfusion syndrome (TTTS) is based on findings of a twin oligo-polyhydramnios sequence (TOPS) observed in monochorionic twin fetuses. However, TTTS can develop without a significant characteristic intertwin discordance in the amniotic fluid volumes. We report an uncommon form of TTTS without TOPS showing severe anemia ...
