[The intraoperative prophylaxis of local ischemical brain damage in neurosurgical patients with cerebral aneurysm].

Aim: To study the effectiveness of intraoperative administration of Cytoflavine for the prevention of ischemic brain injury during cerebral aneurysm (CA) clipping with temporary occlusion of the leading artery under general anesthesia.

Material And Methods: The prospective cohort single-center study included 40 patients with CA ( the main group - 27 patients with intraoperative administration of cytoflavine; the comparison group -13 patients without use of cytoflavine), who underwent aneurism clipping with temporary occlusion of the afferent artery. We assesed the intraoperative state of the brain, the time of awakening and extubation of patients after surgery, neurological deficit and local ischemic changes in the area of surgery according to the CT of the brain in the early postoperative period, resuscitation bed-day and the relationship of these indicators with the duration of temporary occlusion of the afferent artery in the selected groups of patients.

Results: In intergroup comparison, patients of the main group treated with intraoperative cytoflavin showed a reduction in the time of awakening (p=0.013) and the time of extubation (p=0.01) both with temporary occlusion of the afferent artery and in patients without temporary occlusion (p<0.05). The duration of resuscitation bed-day decreased in the main group of patients receiving intraoperatively cytoflavine (p=0.01), as well as in patients in the comparison group without temporary occlusion (p<0.05).

Conclusion: Temporary occlusion of the afferent artery with short intervals of vessel occlusion in combination with intraoperative intravenous administration of cytoflavine expands the tolerability to artery occlusion in patients operated in the 'cold' period, reduces the possibility of neurological deficit, reduces the recovery period and resuscitation bed-day after surgical clipping CA.
