“…На практике применение перфузионных методик в ургентной диагностике инсульта нередко уменьшает число кандидатов для ТЛТ из-за детекции большей площади поражения [44]. По мнению экспертов [45], критический уровень перфузионно/диффузионного несоответствия оценивается в 20%, но в имеющихся рекомендациях и стандартах порог изменений перфузионных показателей − соотношение ядра некроза и ишемической полутени остается открытым.…”

Venous stroke in cerebral venous sinus thrombosis is a rare pathological condition with uncertain diagnostic algorithm to ensure prompt treatment by neurologists and radiologists. All the methods are not obligatory in the workup of acute stroke, except computed tomography (CT) and transcranial Doppler. Researchers and clinicians are commonly guided by their own experiences. Therefore, the diagnosis of venous stroke is an unstable process resulting in its underestimation in the general stroke population. The optimal use of neuroimaging methods within the existing standards of care for patients with stroke, determination of the necessary and sufficient set of diagnostic procedures is an organizational and methodical problem. In addition, there is no complete description of venous ischemic stroke patterns in the medical literature. The article reviews existing evidence-based data on the diagnostic algorithms for venous stroke and discusses the probability of detecting radiologic symptoms based on the diagnostic accuracy and effectiveness of such methods as conventional CT and magnetic resonance imaging (MRI), CT and MR angiography, CT and MR perfusion, transcranial Doppler (TCD) and ultrasound of the brachiocephalic arteries stated in the national and international guidelines, as well as our own experience. Limitations of their use and options to overcome major drawbacks including the introduction of teleradiology are considered.

Aim. To assess the preoperative morphological state of the brain and the state of cerebral circulation in patients referred for coronary bypass surgery to identify predictors of long-term cerebral disorders.Material and Methods. The study included 33 male patients, divided into 2 groups according to the presence or the absence of distant neurological complications 5 years after surgery. All patients underwent non-contrast computed tomography of the brain and perfusion computed tomography. Computed tomography was repeated 5 years after surgery.Results. The perfusion indices in all measurement zones in patients of the two groups did not significantly differ. Significant differences in width of the third ventricle and ventricular-cranial index between patients of groups 1 and 2 were not identified. The incidence rates of leukoaraiosis significantly differed: leukoaraiosis was detected significantly more frequently in group 2 (78% of cases) than in patients of group 1 (31%), p=0.0455.Discussion. The dimensions of the brain cavity system and the preoperative state of the microcirculatory blood flow were not predictors of long-term postoperative neurological disorders. Five years after surgery, patients of group 2 showed clinical and morphological signs of past ischemic changes, which were not detected in patients of group 1 suggesting that leukoaraiosis was an unfavorable prognostic indicator of postoperative cerebrovascular disorders in the long-term period.Conclusion. When referring a patient with the presence of morphological manifestations of cerebral microangiopathy in the form of the leukoaraiosis phenomenon for cardiac surgery, these patients should be considered at risk requiring administration of the necessary set of measures for the prevention of long-term cerebral disorders.
