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.
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).
