Carotid Endarterectomy and Stenting Timing

To compare the safety and efficacy of carotid revascularization performed within 48 hours versus after 14 days in patients with symptomatic carotid stenosis accompanied with MRI-confirmed acute infarction (high signal on diffusion-weighted imaging accompanied by low apparent diffusion coefficient signal) in the responsible vascular territory.

Carotid Endarterectomy Versus Stenting in Patients With Acute Stage of Ischemic Stroke.

The objective of this clinical trial is to compare immediate and long-term results of carotid endarterectomy and carotid stenting in acute period of ischemic stroke. Patients who presented with acute stage of ischemic stroke will be treated by carotid artery stenting in 50 cases and by carotid endarterectomy in 50 cases under regional anesthesia. Patient inclusion criteria: 1. Ischemic stroke in the middle cerebral artery territory 2. Ipsilateral stenosis of the internal carotid artery more than 50% 3. Neurological deficit at the time of surgical treatment: the modified Rankin scale (mRs) score of 0-4 and the US National Institutes of Health (NIHSS) stroke scale score no more than 12 4. The size of the ischemia focus: no more than 1/3 in the territory of the middle cerebral artery brain supply 5. Terms of operation: from 1 to 28 days from the moment of ischemic stroke The primary intra-hospital and/or 30-day study endpoints: 1. Perioperative ipsilateral ischemic stroke. 2. Any stroke: contralateral ischemic or any hemorrhagic stroke. 3. Myocardial infarction. 4. Hemorrhagic complications that required surgical revision of the operating wound or transfusion of blood components. 5. Surgical site infection 6. Death 7. Main adverse cardiovascular events (stroke + myocardial infarction + death).
