Abstract
Background
The effectiveness and safety of intravenous thrombolysis before mechanical thrombectomy (MT) in large cerebral infarctions remains uncertain. This study compares bridging MT, which includes intravenous thrombolysis, to direct MT without it.
Methods
Data from 298 patients with anterior circulation large cerebral infarctions, assessed via non-enhanced CT (ASPECTS 0-5), who underwent MT in two-center cohort studies, were analyzed. Primary outcomes focused on independent ambulation (modified Rankin Scale scores 0-3) at 90 days post-stroke. Safety outcomes included parenchymal hemorrhage (PH) rates and mortality. We conducted a sensitivity analysis considering the timing from symptom onset to imaging within 4.5 hours. Additionally, a meta-analysis of 17 studies involving 3527 patients assessed the interventions' effectiveness and safety, with further scrutiny of high-quality studies (Newcastle-Ottawa Scale ratings 7-9) to increase robustness of results.
Results
No significant differences were found in 90-day independent ambulation between the bridging MT and the direct MT group (adjusted odds ratio [aOR] 1.15, 95% CI 0.68-1.94). Rates of PH and mortality were also similar across groups. These outcomes were consistent in the subgroup imaged within 4.5 hours of symptom onset. The meta-analysis supported these outcomes, showing no improvement in ambulation (aOR 1.16, 95% CI 0.82-1.64) or reduction in PH with bridging MT. Further analysis of high-quality studies supported these results.
Conclusions
The cohort study and meta-analysis provide Class II evidence indicating no significant differences in functional outcomes or hemorrhagic risks between bridging and direct MT for large cerebral infarctions. This suggests that direct MT might be a viable alternative to bridging MT.
期刊介绍:
The Journal of Stroke & Cerebrovascular Diseases publishes original papers on basic and clinical science related to the fields of stroke and cerebrovascular diseases. The Journal also features review articles, controversies, methods and technical notes, selected case reports and other original articles of special nature. Its editorial mission is to focus on prevention and repair of cerebrovascular disease. Clinical papers emphasize medical and surgical aspects of stroke, clinical trials and design, epidemiology, stroke care delivery systems and outcomes, imaging sciences and rehabilitation of stroke. The Journal will be of special interest to specialists involved in caring for patients with cerebrovascular disease, including neurologists, neurosurgeons and cardiologists.
