Abstract

Background: Endovascular thrombectomy (EVT) has become the standard of care for selected patients with acute ischemic stroke within 24 hours of symptom onset. However, the efficacy and safety of EVT for stroke presenting beyond 24 hours is undetermined.

Methods: We performed a systematic review and meta-analysis to examine the outcomes of EVT in patients with acute ischemic stroke beyond 24 hours from onset. The primary outcome was 90-day functional independence defined as the modified Rankin Scale score of 0-2 (mRS 0-2). Secondary outcomes included successful reperfusion defined as Thrombolysis in Cerebral Infarction 2b-3 (TICI 2b-3), symptomatic intracranial hemorrhage (sICH), and 90-day mortality.

Results: Six studies enrolled a total of 5,868 patients to compare the prognosis of EVT for stroke patients treated beyond 24 hours versus within 6-24 hours. The study results indicated that there was no difference in the rate of successful reperfusion (RR 1.00, 95% CI 0.94-1.06, P = 0.96) and sICH (RR 0.63, 95% CI 0.35-1.16, P = 0.14) between the two groups of patients who underwent EVT at different times. Four studies involving 707 patients compared the outcomes of EVT versus best medical treatment (BMT), including thrombolysis, for stroke patients treated beyond 24 hours. Compared to patients receiving BMT, those undergoing EVT were more likely to achieve 90-day functional independence (RR 1.96, 95% CI 1.27-3.01, P < 0.05) and a lower risk of sICH (RR 3.52, 95% CI 1.11-11.20, P = 0.03), with no significant difference in 90-day mortality rates (RR 0.86, 95% CI 0.58-1.28, P = 0.46).

Conclusions: Our study found that the EVT time window did not significantly affect TICI 2b-3 and sICH, and EVT showed better therapeutic effects than BMT for stroke patients beyond 24 hours. Specifically, patients who underwent EVT beyond 24 hours had a higher proportion of functional independence at 90 days and a lower risk of sICH. Therefore, EVT remains an effective treatment option for patients with large vessel ischemic stroke beyond the traditional 24-hour time window.

期刊介绍: World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The journal''s mission is to: -To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care. -To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide. -To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients. Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
