[Methodological approaches for assessment of intracranial aneurisms treatment efficiency].

Recently vascular neurosurgery is on stage of comparing of different techniques for intracranial aneurisms treatment. Clinical and randomized studies provide with data that different drugs and techniques have neuroprotective effect, for example haemogenesis growth factors. To introduce any growth factors in practice the research proving the effectiveness of the drug must be carried out.

[Simvastatin efficacy in vasospasm treatment in patients after aneurysm SAH].

Number of trials had previously demonstrated cerebroprotective effect of statin therapy in SAH patients. Aim of the current study was to assess effects of simvastatin on vasospasm in clinical practice. The study group comprised 35 patients admitted to Burdenko Neurosurgery Institute with aneurysmal SAH in 2007-2011.

[Microsurgical treatment of cerebral arteriovenous malformations in Burdenko Neurosurgical Institute (recent experience)].

Recently the number of AVM resections in Burdenko Neurosurgical Institute has been increased dramatically. Aim of this study was to assess the results of open surgery in our clinic in modern neurosurgical era. Consecutive series if 160 patients with AVM treated using microsurgical technique since 2009 till 2011 was analyzed.

[Thromboelastography as a method for preoperative assessment of hemostasis state in neurosurgical patients on long term aspirin therapy].

The hemostasis state was assessed by routine tests and TEG in 169 patients on long term aspirin therapy. According to TEG results all the patients were divided into three groups: normo-, hypo- and hypercoagulation. The aspirin therapy was interrupted in normo- and hypercoagulation groups, but the surgery was not postponed.

[Monitoring the depth of anesthesia in neurosurgical patients].

The study reports the results of monitoring the depth of anesthesia with BIS technology in 456 neurosurgical patients with different neurosurgical pathology: sub- and supratentorial tumors, aneurisms, arteriovenous malformations, spinal pathology, etc. BIS reflects hypnotic state of the brain during anesthesia in almost all the cases, except for bifon-tal surgical approach when sensor placement is impossible. BIS monitoring of the depth of anesthesia is most advantageous in the following cases: epilepsy surgery, spine surgery with neurophysiological monitoring, awake craniotomy, severe cardiovascular pathology, massive blood loss, neurosurgery in pregnant patients.
