What is hypoxic-ischemic encephalopathy Slideshare?
• Hypoxic-ischemic encephalopathy Is an abnormal neurobehavioral state in which the predominant pathogenic mechanism is impaired cerebral blood flow that may result in neonatal death or be manifested later as cerebral palsy or mental deficiency.
What is HIE MRI?
Neonatal hypoxic-ischemic encephalopathy (HIE) is the result of a global hypoxic-ischemic brain injury in a term neonate, usually after asphyxia.
What area of brain does HIE affect?
Cerebral cortex (deep nuclear): A predominant cerebral cortex (deep nuclear) pattern of injury is present in 35-85% of infants with hypoxic-ischemic encephalopathy.
What is Hie medical?
Electronic health information exchange (HIE) allows doctors, nurses, pharmacists, other health care providers and patients to appropriately access and securely share a patient’s vital medical information electronically—improving the speed, quality, safety and cost of patient care.
What is Hie newborn?
What is hypoxic-ischaemic encephalopathy (HIE)? Hypoxic-ischaemic encephalopathy (HIE) may be diagnosed if your baby’s brain does not receive enough oxygen and/or blood flow around the time of birth. You might hear this being referred to as ‘asphyxia’, ‘birth asphyxia’ or ‘perinatal asphyxia’.
Does HIE show on MRI?
MRI allows to reveal a number of lesions associated with HIE that are invisible on the ultrasound scans (i.e. cortico-subcortical lesions within the central region, bilateral parasagittal lesions and brain stem, thalamus, cerebellum and hippocampus lesions).
Can MRI be normal with HIE?
Infants with mild HIE who are developmentally normal at the age of 2 years do not have normal MRI scans and may be at risk of minor neurological problems by school age.
Can MRI detect hypoxic brain damage?
Magnetic resonance imaging (MRI) is more sensitive than computed tomography at detecting stroke in the early phase, subtle abnormalities related to anoxic/hypoxic encephalopathy, and diffuse axonal injury (DAI) in patients with TBI.
How is hypoxic ischemic encephalopathy treated?
At present, there is no true cure for hypoxic-ischemic encephalopathy (HIE). However there is one treatment, called therapeutic hypothermia, that can reduce the extent of permanent brain damage if given very shortly after birth or the oxygen-depriving incident.
Can HIE be cured?
Hypothermia treatment has been proven to be an effective way to limit the lasting damage and long-term disabilities that babies born with HIE experience. However, there is no cure for HIE, and any baby may face disability because of it, regardless of treatment.
Is HIE curable?
Can you see HIE on an MRI?
Can a baby with brain damage recovery?
Children may be able to recover completely from mild cases of brain damage. However, severe cases can lead to lifelong disability and may require lifelong medical treatment. Severe newborn brain damage can lead to other conditions such as cerebral palsy.
Which imaging is used to diagnose hypoxic-ischemic brain injury?
MRI. MRI is the most sensitive and specific imaging technique for examining infants with suspected hypoxic-ischemic brain injury. Conventional sequences can help exclude other causes of encephalopathy such as hemorrhage, cerebral infarction, neoplasms, or congenital malformations.
What is hypoxic-ischemic brain injury (HII)?
Hypoxic-ischemic injury (HII) to the brain is a devastating occurrence that frequently results in death or profound long-term neurologic disability in both children and adults. Treatment of HII consists largely of supportive care, which does little to prevent the ongoing injury that occurs in the hours immediately following the causative insult.
When is MR imaging indicated in the evaluation of hemiplegic intracranial injury (HII)?
If clinical suspicion for HII remains, MR imaging should be performed to evaluate for the presence and severity of injury.
Is proton MR spectroscopy a useful tool in the evaluation of HII?
Proton MR spectroscopy has become a valuable tool in the evaluation of HII, particularly in the perinatal period.
