Abstract:
It remains controversial if intravenous thrombolysis (IVT) prior to mechanical thrombectomy (MTE) is superior to MTE alone in patients with acute ischemic stroke caused by large vessel occlusion. We aim to compare functional outcomes, mortality, reperfusion, and intracranial hemorrhage rates in bridging therapy (IVT prior thrombectomy) and MTE alone groups within 6 h from symptom onset. Materials and Methods: Consecutive hospitalized patients (September 2017 and July 2018) with acute large artery occlusion within the anterior cerebral circulation eligible for MTE with or without prior IVT were included. A modified Rankin Scale score of 0 to 2 was considered as good functional outcome at 90 days. Successful reperfusion was defined as a Thrombolysis in Cerebral Infarction scale of 2b to 3. Results: Of the 124 patients included, 56 (45.2%) received bridging therapy and 68 (54.8%) received MTE alone. Patients receiving bridging therapy were younger (median, 56 vs 63, P = .045) and had shorter onset-to-groin time (median, 270 vs 370 min, P 〈 .001) than those receiving MTE alone. Successful reperfusion rate was significantly greater in the bridging therapy group (87.5% vs 72.1%, P = 0.03). There were no statistically significant differences between the 2 groups in functional independence (bridging 58.9% vs 75.0%, P = 0.07), mortality at 90 days (bridging 14.3% vs 7.4%, P = 0.22), parenchymal hematoma type 2 (bridging 3.6% vs 2.9%, P 〉 .99), and any hemorrhage (bridging 42.3% vs 26.5%, P = 0.07). Conclusion: Compared to MTE alone, bridging therapy with IVT improved the reperfusion rate but not other outcomes. Further clinical trials are needed to confirm our findings.
