| description | The lecture is devoted to the peculiarities of changes in tissue and cell perfusion of the brain with a rare pathology – venous ischemic stroke. Venous stroke, being a “relatively unknown cerebrovascular disease”, occurs up to 5 % of all cases of stroke. The terms “venous ischemia” and “venous stroke” have long been used in the literature and the definition of the venous nature of stroke should lead to a change in therapeutic tactics. Neuroimaging should ensure the verification of stroke and cerebral venous sinus thrombosis, which are the main cause of such a stroke. A certain “alertness” to the venous nature of the stroke with the expansion of the volume of radiologic methods of investigation and the performance of angiographic and perfusion CT and MR techniques, diffusion MRI allowed to increase the number of diagnosed and verified venous strokes from 0.4 % of the total number of stroke patients to 2.4 %. A distinctive feature of venous ischemic stroke from the arterial is moderate hyperemia in the central part in cases where necrosis does not develop and perifocal hyperperfusion in the development of necrosis. Moderate plethora, defined by perfusion parameters (up to 30 % CBF, CBV, MTT) of CT, MRI and SPECT techniques, and not oligemia is the primary damaging factor of the pathogenesis of venous stroke in contrast to the arterial and hyperemia patterns should be the reference points in emergency diagnosis venous stroke along with tomoangiographic symptoms of cerebral venous sinustrombosis. |
