Use of Middle Cerebral Artery Visualization with Coronal Computed Tomography to Access Target Artery in..., Background: When introducing a microguidewire into an occluded vessel during mechanical thrombectomy (MT), visual information on the vessel course distal to the occluded site could help to avoid perforation., Background: When introducing a microguidewire into an occluded vessel during mechanical thrombectomy (MT), visual information on the vessel course distal to the occluded site could help to avoid perforation. We examined whether visualization of the middle cerebral artery (MCA) by coronal images of nonenhanced computed tomography (coronal CT) provides useful preoperative information on the vessel course in the setting of MT. Methods and Results: We retrospectively studied 29 patients with ischemic stroke of the internal carotid artery and MCA occlusion who were admitted to our hospital within 4.5 hours from stroke onset and underwent MT., admin,
