    Abstract:
    OBJECTIVE: Although intravenous thrombolysis (IVT) is recommended among acute ischemic stroke (AIS) patients secondary to large vessel occlusion (LVO) undergoing mechanical thrombectomy (MT), time delays with bridging therapy (IVT prior to MT) and its potential benefit remains unclear. We compared the time delays and clinical outcomes among AIS SECONDARY TO LVO patients treated with bridging therapy or direct MT (dMT) at a comprehensive stroke center (CSC). METHODS: We performed a retrospective analysis of prospectively collected data of AIS secondary to LVO patients admitted between 2012 and 2017 at a large volume CSC. AIS secondary to LVO patients arriving directly from field to CSC within 4.5 h were included. Demographic characteristics, clinical and radiological data, treatment and procedural information were extracted and analyzed. RESULTS: Among 777 AIS secondary to LVO patients treated with MT, 237 patients (156 dMT, 81 bridging therapy) were included. Mean age was 70.3 year-old, median NIHSS score was 18, and door-to-needle time was 40 min (IQR 31-56 min). The median door-to-puncture (DTP) time was 22 min longer in bridging therapy group in comparison to dMT group, 74 vs 52 min (p<0.001). Additionally, no difference was observed between the groups for successful recanalization or functional independence. CONCLUSION: At a large volume CSC, bridging therapy (vs. dMT) was observed to have a longer DTP time without any difference in successful recanalization or clinical outcomes.
