Possible reasons for late term:
Trisomy 21: Down Syndrome
Trisomy 13 & 18: mental retardation, 90 percent of babies born with it die before the age of 1.
Anencephaly: a severe head disorder, occurs when the head end of the neural tube fails to close, absence of a major portion of the brain, skull, and scalp. Children with this disorder are born without a forebrain, the largest part of the brain. The remaining brain tissue is often exposed—not covered by bone or skin.
Polycystic Kidney Disease: cysts on the babies kidney. It takes many years for this to cause the kidneys to fail and can be treated with dialysis or kidney transplantation. 600,000 people in the U.S. are living with PKD.
Spina Bifida: the most common permanently disabling birth defect in the U.S. The spine of the baby fails to close, he or she won’t be able to walk. 70,000 people in the U.S. are living with SB.
Hydrocephalus: there is an excessive amount of fluid in the brain. Infants experience vomiting, large head size, sleepiness, irritability, downward deviation of the eyes (“sunsetting”) and seizures. Older children and adults may experience different symptoms such as, headache followed by vomiting, nausea, papilledema (swelling of the optic disk which is part of the optic nerve), blurred or double vision, sunsetting, problems with balance, poor coordination, gait disturbance, urinary incontinence, slowing or loss of developmental progress, lethargy, drowsiness, irritability, or other changes in personality or cognition including memory loss. Hydrocephalus is very treatable.
Potter’s Syndrome: there is a total absence or malformation of infant kidneys. Vast majority of babies die at birth or shortly afterwards.
Lethal Dwarfism: this is very rare. Some symptoms are a large head, wide front fontanel, corneal clouding, closed off ear canals, and very short arms. Nearly half of the babies that have this die before they’re born.
Holoprosencephaly: In most cases, the brain does not divide into lobes, which severely deforms the skull and face. Sometimes the brain is partially or nearly divided, making the symptoms much less severe. In the absolute worst cases, the baby dies in the womb.
Anterior and Posterior Encephalocele: this complication leads to chromosomal anomaly, most common anomaly being Trisomy 18. Patients with an anterior encephalocele have a 100% survival rate, but only 55% in persons with a posterior encephalocele. Encephalocele reduces the chance of live birth to 21%, and only half of those live births survive. Approximately 75% of survivors have a mental deficit. The absence of brain tissue in the herniated sac is the single most favorable prognostic feature for survival.
Non-Immune Hydrops: Excess of extra-cellular fluid in two or more sites without any identifiable circulating antibody to red cell antigens. There are treatments to perform while the baby is still in the womb, however the prognosis is generally very poor with very high peri-natal mortality.
