Abstract
Recanalization after large vessel occlusion is proven to be a crucial predictor for favorable outcome in acute ischemic stroke. Intravenous thrombolysis with recombinant tissue plazminogen activator (rtPA) has been investigated in several randomized controlled studies and is shown to be a safe and effective treatment.
However, efficacy of this therapy is moderate. Mechanical thrombectomy represents further step in the treatment of acute stroke.
Several prospective randomized studies proved benefit of the endovascular treatment based on proof of proximal artery occlusion, rapid and effective imaging methods to exlude patients with a large infarct core and efficient workflow to achieve fast recanalization and high recanalization rate. Using the stent-.retriever technique proved to be higly technically and clinically effective.
