Endovascular thrombectomy (EVT) is the recommended option for acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) that within 6 h onset of stroke. The EVT treatment time window has been extended to 24 h in carefully selected patients by DAWN trial. Recent evidences indicated that some patients presented beyond 24 h still potentially benefit from EVT treatment. Herein, we describe one case of successful delayed EVT in a 50-year-old male AIS patient with an 8-day history of left middle cerebral artery occlusion. Before surgery, CT perfusion demonstrated a marked left hypoperfusion with penumbra volume of 127 mL and ischemic core volume of 10 mL. EVT was performed with complete recanalization and significant improvement in his neurological deficits at 90-days post-surgery follow-up. In future, more randomized clinical trials are warranted to further confirm the safety, efficacy, as well as the applicable population of delayed EVT.
