ДИАГНОСТИКА И РОЛЬ ЦЕРЕБРАЛЬНОГО ВЕНОЗНОГО ПОЛНОКРОВИЯ В ТЕЧЕНИИ И ИСХОДАХ НЕГЕМОРРАГИЧЕСКОГО ИНСУЛЬТА

The cerebral venous congestion is the primary factor in damaging the brain with cerebral venous thrombosis. Ischemia in stroke associated with cerebral venous sinusthrombosis (CVST) is secondary, developing as a result of externally induced constriction of the blood vessels feeding the area of stasis in vasogenic edema, which leads to necrosis is less likely than with arterial ischemic stroke. Stroke associating CVST more often accompanied by hemorrhagic transformation than atherothrombotic. Venous congestion is detected in cardioembolic stroke in the perifocal zone of the ischemic focus, and probably plays a role in the courses and outcomes of stroke, contributing to the development of vasogenic edema and early secondary hemorrhage. Identify venous stasis in principle possible using the technique of determining the ultrasound index arteriovenous ratio and sighting in the ischemic focus and perifocal zone as hyperperfusion using perfusion techniques MSCT or MRI of the brain.
