Objective To investigate the value of prevention of
cerebral ischemia with multi-modality neuroelectrophysiological
monitoring in
intracranial aneurysm embolization.
Methods The clinical data of 44
patients with
intracranial aneurysm treated with endovascular embolization from May 2013 to June 2014 were analyzed retrospectively. The
patients were divided into two groups according to whether they used intraoperative neuroelectrophysiological
monitoring. There were 21
patients in a
monitoring group and 21 in a non-
monitoring group. According to the site of the
aneurysms,
somatosensory evoked potential ( SEP),
motion evoked potential( MEP),
scalp electroencephalogram,and
brainstem auditory evoked potential (BAEP)were monitored,and at one day after
procedure,their newly developed neurological deficits and the follow up
observation after 3 months in both groups were compared and analyzed. Results The intraoperative SEP,MEP,and
scalp EEG changes in the
monitoring group were observed in 9,3 and 4
patients,respectively. Timely preventive
measures were taken for 9 of the
patients with
cerebral ischemia revealed by neuroelectro-
physiological monitoring. At the first day after
procedure,the
incidence of
patients with new neurological deficit was 17. 4%(4/23)in the
monitoring group,and that was 47. 6%(10/21)in the non-
monitoring group. There was significant difference between the 2 groups(χ2 =4. 623;P<0. 05). There was significant difference in the good
prognosis rates(87. 0%[20/23]vs. 57. 1%[12/21])after 3-month follow-up (χ2 =4. 919;P<0. 05)between the 2 groups. There were no deaths in both groups. Conclusion Multimode in combination with neuroelectrophysiological
monitoring may decrease ischemic
complications in
aneurysm interventional
treatment and improve the
safety of
procedure.
