КРИТЕРИИ ДИАГНОСТИКИ НЕГЕМОРРАГИЧЕСКОГО ВЕНОЗНОГО ИНСУЛЬТА МЕТОДАМИ РЕНТГЕНОВСКОЙ МУЛЬТИСПИРАЛЬНОЙ КОМПЬЮТЕРНОЙ (МСКТ) И МАГНИТНО-РЕЗОНАНСНОЙ (МРТ) ТОМОГРАФИИ

Purpose. The study was aimed at detecting the signs of focal and perifocal injury in venous strokes and their differences from those in arterial strokes by urgent CT and MRI. Materials and methods. The diagnosis of a venous stroke was verifi ed by neurovisualization (native MSCT, perfusion CT or CT angiography, conventional MRI and MR-angiography) and during autopsy (in case of a fatal outcome). Results. Patients with venous strokes had a hyperdense (by routine CT) stroke-related vessel, compensatory venous distention on the side of the occlusion, early haemorrhagic transformation, the changes localized in the region of the affected vein. Conclusions. The study allowed to detect CT and MRI signs, which can help to differentiate arterial and venous strokes.
