Early mechanical thrombectomy (MT) with successful recanalization leads to better outcomes following acute ischemic stroke. However, reocclusion of the treated vessel can occur in certain patients. It is important to identify those patients who are at high risk for such events so that measures can be taken to prevent potential neurological deterioration.
The study by Marto et al. published in Stroke in August 2019 sought to address this very topic. The authors examined data from the Acute Stroke Registry and Analysis of Lausanne cohort and included patients with anterior and posterior circulation strokes who were treated with MT, with resultant TICI 2B-3, and had 24-hour vascular imaging available. Reocclusion was defined as a new intracranial occlusion within an arterial segment that was recanalized at the end of MT.
