Monochorionic twins (MC) are at increased risk for morbidity. The unique placenta with vascular anastomoses may create imbalance with either acute or chronic hypotension or cardiac insufficiency that will eventually affect the fetal brain. It appears that these characteristics of the MC placenta add to the already higher frequency of brain anomalies observed
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...
Congenital anomalies are a major cause of fetal and neonatal death and of childhood morbidity. Chromosomal and other genetic abnormalities, environmental teratogens and some nutritional deficiencies account for some congenital anomalies but the majority are of unknown etiology. The hypothesis is here proposed that a significant proportion of congenital anomalies and cerebral palsy of unknown et...
Monochorionic twins share a single placenta with intertwin vascular anastomoses, allowing the transfer of blood from one fetus to the other and vice versa. These anastomoses are the essential anatomical substrate for the development of several complications, including twin-twin transfusion syndrome (TTTS) and twin anemia-polycythemia sequence (TAPS). TTTS and TAPS are both chronic forms of feto...
It is usually held that there is a time continuum in the formation of monoxygotic (MZ) twins which is indexed by their placentation, running from dichorionic to monochorionic diamniotic to monochorionic monoamniotic and conjoined pairs. There is good evidence that this continuum is characterised by a continuum of predisposition to anencephaly, slightly raised in dichorionic pairs but very high ...
