Albers GW, et al. - The purpose of this trial was to inspect the outcomes of thrombectomy in patients, 6 to 16 hours after they were last known to be well, and who had remaining ischemic brain tissue that was not yet infarcted with selection by perfusion imaging. When compared to standard medical therapy alone, endovascular thrombectomy for ischemic stroke 6 to 16 hours plus standard medical therapy led to better functional outcomes among patients with proximal middle-cerebral-artery or internal-carotid-artery occlusion and a region of tissue that was ischemic but not yet infarcted.
