Target artery occlusion impact and the Willis circle impact on the ischemic stroke outcome after the successful thrombectomy

The article shows the Willis circle effect on the ischemic stroke outcome after successful endovascular thrombectomy with anterior circulation isolated cerebral artery occlusion and combined with extracerebral artery occlusion.Objective: To identify the stroke outcomes difference after successful thrombus removal from the anterior circulation artery, depending on the acute combined nature occlusion and the anatomical and physiological characteristics of the arterial brain circle.Methods: A thrombectomy group with combined middle cerebral and internal carotid arteries combined occlusion is represented by 26 patients. Another 26 patients underwent thrombectomy with isolated middle cerebral artery occlusion. The Willis circle anatomical features and the concomitant brachiocephalic arteries atherosclerotic lesion were retrospectively analyzed. A statistical evaluation of inpatient treatment results and complications of these groups was carried out using nonparametric methods...
