The fetal demise of one of the twins during the second trimester of a monochorionic pregnancy can result in serious complications to the surviving fetus. Complications include gangrenous limbs, hands and feet, cerebral palsy and IQ deficits, constriction rings of limbs and digits, reduced digits , skin defects, brain cysts , hydranencephaly ...
Evidence of brain injury related to the hypoxic-ischemic events that cause neonatal encephalopathy can be seen with brain MRIs, CTs, magnetic resonance spectroscopy imaging or ultrasounds. [9] [10] Neonatal encephalopathy may be assessed using Sarnat staging. [11] Brain MRI is usually performed within eight days of life. [12]
Alcohol: Use during pregnancy can cause fetal alcohol syndrome and fetal alcohol spectrum disorder. [67] Tobacco use: During pregnancy, causes twice the risk of premature rupture of membranes, placental abruption and placenta previa. [68] Also, it increases the odds of the baby being born prematurely by 30%. [69]
The cause of TAPS is slow and persistent unbalanced feto-fetal transfusion through tiny placental anastomoses, which progressively results in highly discordant hemoglobin levels. This causes the recipient twin to become polycythemic and the donor twin to become anemic. [1]
Additionally, hypotension resulting from fetal distress or cesarean section births can lead to decreased blood and oxygen flow to the developing brain. These hypoxic-ischemic incidents can cause damage to the blood brain barrier (BBB), a system of endothelial cells and glial cells that regulates the flow of nutrients to the brain. A damaged BBB ...
[10] During pregnancy, women with preeclampsia faces serious risk of damage to vital organs such as the kidneys, liver, brain, and the blood system. This hypertensive disorder may also cause damage to the placenta leading to issues such as premature births, miscarriages, placental abruption, or even stillbirths. In some cases, preeclampsia can ...

Perinatal asphyxia (also known as neonatal asphyxia or birth asphyxia) is the medical condition resulting from deprivation of oxygen to a newborn infant that lasts long enough during the birth process to cause physical harm, usually to the brain. It remains a serious condition which causes significant mortality and morbidity.
