The acute disturbance of cerebral blood flow of ischemic nature, in medium cerebral artery of the right hemisphere with left-sided hemisyndrome
developed as a result of atherosclerosis of cerebral vessels and hypertension.
Examination on day 7 after the surgical procedure showed neurological abnormalities in 10 infants (brain damage group: hypotonia-hypertonia syndrome, n<4; seizures, n = 2; hemisyndrome
, n = 4), and in these infants neurological abnormalities were still present at the 2-year follow-up (hypotonia-hypertonia syndrome, n = 6; hemisyndrome
, n = 4).
Other CNS abnormalities included seizures (43%), paresis (21%), learning difficulties (11%), and hemisyndrome
Neurologic examinations on day 7 after the surgical procedure revealed neurologic abnormalities in 9 infants (brain-damage group: hypertonia/hypotonia syndrome, 6 patients; hemisyndrome
, 3 patients) whose stays in the NICU were significantly longer (P <0.001) than in the group with no brain injury.
Neurologic examinations were performed daily, and neonatal neurologic conditions were classified as described by Prechtl (22), with each infant assigned to one of three diagnostic groups: normal, abnormal (when one or more of the following neurologic syndromes were present: hyper- or hypokinesia, hyper- or hypotonia, hemisyndrome
, apathy syndrome, hyperexcitability syndrome), or suspect (if only isolated symptoms were present but no defined syndrome was evident).
