Abdominal trauma, high uterine pressures, hyperstimulation of the uterus, high blood pressure, or seizures in the mother may also lead to a lack of blood and oxygen reaching the baby's brain. (millerandzois.com)
Ischemia was achieved by gradually obstructing the umbilical cord to regulate the amount of blood reaching the fetus. (ibecbarcelona.eu)
There is a buildup of blood below the innermost two membranes that cover the brain, which can cause seizures and cerebrospinal fluid buildup in the brain, or hydrocephalus, and apnea. (medicalmalpractice.net)
Brain hemorrhage occurs when blood vessels leak into the brain. (candallaw.com)
Brain ischemia occurs whenever blood flow to the brain becomes blocked. (cullanlawaz.com)
Lack of blood flow causes decreased oxygen which leads to the infant's brain cell death. (cullanlawaz.com)
Additionally, a seizure may happen when the brain is flooded with blood (brain hemorrhage) or when the brain doesn't have enough blood (brain ischemia). (birthinjuryguide.org)

So "seemingly similar" may not be because we just do not have the tools to measure the real extent of the brain insult with HIE. (millerandzois.com)

The term hypoxia refers to a lack of oxygen to organs or tissues. (millerandzois.com)
A subarachnoid hemorrhage is a bleed that occurs between the tissues that cover the brain. (medicalmalpracticehelp.com)

Ali G. Saad, M.D. , a Miller School professor, neuropathologist and director of the pediatric and perinatal pathology service at Holtz Children's Hospital, examined both placentas and found signature placental pathological changes caused by SARS-CoV-2 in both, and also examined major changes in the brain that came to autopsy.

[ 3 , 4 ] Further refinements in CPB hardware and techniques, perfusion methods, myocardial and brain protection over the past seven decades contributed to improved outcomes of surgical treatment of CHD. (medscape.com)

Tumor necrosis factor alpha (TNF-a), interleukin-1 beta (IL-1b) and interleukin-2 (IL-2) are overexpressed in affected brains, and receptors for these cytokines are present on many inflammatory and neural cells in the white matter. (eurekaselect.com)
