“…Placental disorders associated with these later complications include unequal placental sharing, placental anastomoses (vessels from one twin being drained by the co-twin forming a unidirectional shunt), and placental inflammation. Additional risk factors include use of assisted reproductive technology (ART), young or old maternal age, prematurity, and low birth weight (Hall, 2003;Painter, Medland, Montgomery, & Hall, 2013).…”

Twins have an increased risk for congenital malformations and disruptions, including defects in brain morphogenesis. We analyzed data on brain imaging, zygosity, sex, and fetal demise in 56 proband twins and 7 less affected co-twins with abnormal brain imaging and compared them to population-based data and to a literature series. We separated our series into malformations of cortical development (MCD, N = 39), cerebellar malformations without MCD (N = 13), and brain disruptions (N = 11). The MCD group included 37/39 (95%) with polymicrogyria (PMG), 8/39 (21%) with pia-ependymal clefts (schizencephaly), and 15/39 (38%) with periventricular nodular heterotopia (PNH) including 2 with PNH but not PMG. Cerebellar malformations were found in 19 individuals including 13 with a cerebellar malformation only and another 6 with cerebellar

Multiple pregnancy is condition where more than one offsprings are formed. This result from either fertilization of more than one ovum individually by separate sperms or division of fertilized ovum. The implantation sites may be in different part of the genital organs and even the peritoneal cavity. The physiology of monozygotic multiple pregnancy is not fully understood as the trigger has not yet been identified. The incidence of multiple pregnancy is increasing, and this is as a result of assisted reproductive technologies.
