Abstract Background Neonatal encephalopathy with seizures after general anesthesia not occurring in infants undergoing cardiac or major neurosurgery is very uncommon. An ischemic origin due to cerebral hypoperfusion from perioperative hypotension has been suggested, but there is a lack of a consensus definition for intraoperatory hypotension in neonates. Case Report We report the first case of neonatal encephalopathy with seizures in a neonate with anorectal malformation. He underwent a colostomy with caudal anesthesia combined with light general anesthesia. Intraoperative systolic blood pressure and mean blood pressure values were considered normal. Thirty-two hours after the intervention, the patient presented electroclinical seizures. Diffusion-weighted imaging showed bilateral involvement with reduced diffusivity in the watershed areas of the middle cerebral artery and posterior cerebral artery. Conclusion Perioperative monitoring of blood pressure is not enough in neonatal surgery. Cerebral magnetic resonance imaging should be considered in infants with noncardiac congenital anomalies after neonatal surgery and long-term follow-up is required.

Internal carotid arterial dissection is a rare and probably underestimated cause of neonatal stroke. We report a case of neonatal stroke underscoring the role of Doppler sonography of the intracranial arteries for the diagnosis and follow-up tool. [ABSTRACT FROM AUTHOR]

Background: Apparent diffusion coefficient (ADC) quantification has been proven to be of prognostic value in term newborns with hypoxic-ischaemic encephalopathy (HIE) who were treated under normothermia. Objectives: To evaluate the prognostic value of ADC in standardized brain regions in neonates with HIE who were treated with therapeutic hypothermia (TH). Methods: This prospective cohort study included 54 term newborns who were admitted with HIE and treated with TH. All magnetic resonance imaging examinations were performed between days 4 and 6 of life, and ADC values were measured in 13 standardized regions of the brain. At 2 years of age we explored whether ADC values were related to composite outcomes (death or survival with abnormal neurodevelopment). Results: The severity of HIE is inversely related to ADC values in different brain regions. We found that lower ADC values in the posterior limb of the internal capsule (PLIC), the thalami, the semioval centre, and frontal and parietal white matter were related to adverse outcomes. ADC values in the PLIC and thalami are good predictors of adverse outcomes (AUC 0.86 and 0.76). Conclusions: Low ADC values in the PLIC, thalamus, semioval centre, and frontal and parietal white matter in full-term infants with HIE treated with TH were associated with a poor outcome.

The article presents a case study a 3-month girl who was treated for breathlessness and cough at the emergency department. PHASE syndrome was suspected and performed cranial angiography-magnetic resonane imaging (angioMRI) which revealed dolichoectasia, left intracavernous carotid artery aneurysm and right middle cerebral artery stenosis. Furosemide therapy was initiated where hypertension and breathlessness disappeared.
