Abstract

BackgroundEndovascular therapy (EVT) for stroke due to distal or medium vessel occlusion (DMVO) is safe. Due to the distinct anatomical characteristics of DMVOs, further evaluation of EVT is crucial to determine which devices may yield better outcomes.MethodsA retrospective analysis of adults with DMVO treated in 37 centers (11 countries) was queried. The primary outcome of favorable shift in 90-day modified Rankin Scale (mRS) was compared between patients treated with Trevo versus other devices on first pass using 1:1 propensity score matching (PSM) with multivariable adjustment. Secondary outcomes included the number of pass attempts, final thrombolysis in cerebral infarction (TICI) score 2b-3, symptomatic intracranial hemorrhage (sICH), improvement in National Institutes of Health Stroke Scale (NIHSS) at 24h, and 90-day mortality.ResultsOf the 1115 included patients, 264 (24%) were treated with Trevo (PSM cohort of 261 per group). Trevo use was not associated with a favorable 90-day mRS shift (proportional odds ratio [OR] 1.10, 95% confidence interval [CI] 0.80-1.51). Trevo was associated with fewer passes (adjusted β=-0.25, 95% CI -0.48 - -0.03), higher odds of TICI 2b-3 (adjusted OR 1.97, 95% CI 1.11-3.49), and a greater 24h NIHSS improvement (adjusted β= -1.74, 95% CI -3.11 - -0.36), with no difference in sICH or mortality (p>0.05). Results were similar in sensitivity analyses.ConclusionsWe observed no safety concerns with Trevo as compared to other EVT devices for DMVO recanalization. There was a signal of better technical efficacy and early clinical improvement.

Distribution in change in NIHSS by 24 h. Violin plot illustrating difference between 24-h and pre-intervention mRS according to device, with negative numbers indicating a reduction (improvement) in NIHSS (p < 0.01 for difference). Open circles represent the median change, with horizontal lines connecting the interquartile ranges of the two groups and vertical spikes reflecting upper- and lower-adjacent values (upper quartile + 1.5 the interquartile range and lower quartile - 1.5 the interquartile range). A red horizontal reference line at 0 indicates no improvement in NIHSS. NIHSS denotes the National Institutes of Health Stroke Scale.
