Comparison of mechanical thrombectomy with Tigertriever versus Solitaire X stent retriever in real-world practice: A matched-pair retrospective analysis.
Article in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BackgroundThe Tigertriever (Rapid Medical, Israel) is the first manually expandable stent retriever, designed to enhance clot engagement and vessel wall apposition. Despite increasing use, comparative data with the widely adopted Solitaire X device (Medtronic, USA) are limited. This study aimed to compare the safety and efficacy of Tigertriever versus Solitaire in mechanical thrombectomy (MT) for acute ischemic stroke due to large vessel occlusion.MethodsWe retrospectively analyzed 346 MT procedures (May 2019-September 2024). Patients treated with Tigertriever or Solitaire X (with/without aspiration) were matched 1:1 using a nearest-neighbor approach based on age, National Institutes of Health Stroke Scale, Alberta Stroke Program Early CT Score, and occlusion site. Outcomes included procedural safety (complications, hemorrhage, mortality) and efficacy (number of passes, time to reperfusion, final modified treatment in cerebral infarction, and 3-month modified Rankin Scale) were compared, with propensity score adjustment applied in the analyses.ResultsIn total, 268 matched patients (134 per group) were included. Baseline characteristics were balanced, except that Tigertriever patients had longer onset-to-puncture times and more cardioembolic strokes. The Solitaire X group demonstrated a significantly higher first-pass recanalization rate (
