Research progress of endovascular thrombectomy in acute ischemic stroke patients beyond 24 hours

Abstract

Abstract:

In recent years, endovascular thrombectomy (EVT) has emerged as a pivotal treatment for acute ischemic stroke (AIS) caused by acute large vessel occlusion. Studies have confirmed that EVT is safe and effective for AIS patients within 24 hours of onset, provided they meet specific imaging criteria. However, the safety and efficacy of EVT for patients beyond the 24-hour window remain to be fully elucidated. This article provides a comprehensive review of recent research progress concerning imaging screening criteria, recanalization rates, clinical prognosis, and the risk of symptomatic intracranial hemorrhage (sICH) in AIS patients treated with EVT beyond 24 hours.

Key words: Endovascular thrombectomy, Large vessel occlusion, Acute ischemic stroke
