Recanalization of the Embolically Occluded Middle Cerebral Artery in Acute Stroke Patients: Noninvasive Assessment and Outcome

摘要: The timing of spontaneous recanalization an embolically occluded intracerebral artery is unknown, as modification the size infarction and clinical course by rapidity degree reperfusion. Most recanalized middle cerebral arteries (MCAs), after arterioarterial or cardiogenic embolic occlusions, occur within first days [3, 5, 7, 12]. Even under favorable conditions, however, severely ischemic brain tissue can not survive longer than several hours [1, 6], rapid at early time would be expected to decisive for recovery. quality leptomeningeal anastomoses, particularly during hours, another important factor modifying both outcome [2, 11].
