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...

Abnormal fusion of the Müllerian ducts or failure of resorption of the septum causes varying degrees of congenital uterine malformation. They are often associated with reproductive problems such as miscarriage, premature labour, premature rupture of the membranes, or malpresentation. Twin gestation in a case of bicornuate uterus is extremely rare. A 37-year-old multiparous woman conceived a twi...

Fetal cholelithiasis is a rare finding during a third-trimester ultrasound with an average incidence rate of 0.07-1.15%. We report a case of fetal cholelithiasis in twins, observed in a patient with monochorionic diamniotic twin pregnancy hospitalized at our unit for signs of premature labor. We present the outcome of the 2 neonates with a clinical and sonographic follow-up. In addition, we off...

Monochorionic twins are usually monozygotic and thus usually have the same sex. A case of monochorionic diamniotic twins following IVF/ICSI and laser treatment of the zona pellucida ("assisted hatching") is presented in which partial embryo amalgamation appears to have occurred. Discordant sex between the twins was suspected on detailed antenatal ultrasound at 13 + 3 weeks gestation and was con...

Monoamniotic twins are known to be at risk of cord entanglement, and have an elevated perinatal morbidity and mortality associated with this. We present a case of cord entanglement in a monochorionic diamniotic (MCDA) twin pregnancy thought to be due to spontaneous septostomy. Unfortunately the cord entanglement was detected postpartum, and ultimately resulted in the demise of one of the twins....

Acardiac twinning is a rare congenital anomaly of monozygotic twin pregnancy which often results from abnormal placental vascular anastomosis. It leads to twin reversal arterial perfusion with complex pathophysiology. Current information on early recognition and treatment for salvation of the normal twin is based on individual case reports in the literature. Mortality of Acardiac twin is 100%. ...

We report on the prenatal diagnosis through array CGH of a dichorionic–diamniotic (DC/DA) twins discordant for Cri du Chat Syndrome. Structural anomalies on one of the twins lead to amniotic fluid sampling, which revealed a partial deletion on the short arm of the chromosome 5. Selective feticide of the affected twin was performed at 34 + 1 weeks' and elective Cesarean section at 37 + 2 weeks. ...
