Rescue stenting after failure of endovascular thrombectomy for acute vertebrobasilar artery occlusion: data from the PERSIST registry

Among acute vertebrobasilar artery occlusion (VBAO) patients, successful reperfusion is a strong predictor of favorable outcomes. However, failed reperfusion (FR) with endovascular thrombectomy (EVT) in VBAO was observed to occur in 18-50% of cases. We aim to evaluate the safety and efficacy of rescue stenting (RS) for VBAO after failed EVT.
