Aims and objectives: Evaluating of the role of dynamic CT- brain perfusion control for determination of necessity, efficiency and sufficiency of endovascular treatment of the multifocal stenotic and occlusion lesions of cerebral artery. 

Methods and materials: The choice of staging and capacity of endovascular treatment of multifocal stenotic and occlusion lesions of cerebral arteries depends on degree of perfusion deficit in different arterial basins and changes of these parameters after each endovascular session. 74 patients with multifocal stenotic and[...]

Results: The choice of sequence, staging and capacity of endovascular treatment of multifocal stenotic and occlusion lesions of cerebral arteries depended on degree of brain perfusion deficit and compensatory reactions in different arterial basins and changes of these parameters after each endovascular sessi[...]

Conclusion: The usage of dynamic CT-brain perfusion control allows to define optimal  sequence, staging and volume of endovascular treatment of multifocal stenotic and occlusion lesions of cerebral arteries. Endovascular methods of treatment of multifocal stenotic and occlusion lesions of cerebral arteries[...]
