Comparison of early versus late rescue stenting after failed thrombectomy for intracranial atherosclerosis-related large vessel occlusion.

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 optimal timing for rescue stenting (RS) following failed thrombectomy in patients with underlying intracranial atherosclerosis (ICAS)-related large vessel occlusion (LVO) remains unknown. We aimed to determine this by comparing the angiographic and clinical outcomes of early and late RS.
methodsWe retrospectively enrolled patients with acute ischemic stroke who underwent stent-retriever thrombectomy for ICAS-related LVO. Per-pass analysis was performed to assess recanalization rates after each retrieval in all patients. Patients were classified into early and late groups based on the number of stent retrievals before RS (early: 1 or 2 attempts; late: ≥ 3 attempts). Angiographic and clinical outcomes were compared between these two groups.
resultsAmong 126 patients with ICAS-related LVO, 257 retrievals were evaluated. Successful and complete recanalization rates were highest on the first attempt and significantly decreased between the second and third passes. Overall, 56 patients underwent RS, of which 27 and 29 were classified into the early and late RS groups, respectively. The early RS group had shorter procedure times (45 min vs. 70 min, p < 0.001) and higher rates of favorable outcomes (85.2% vs. 55.2%, p = 0.014) than the late RS group. Intact stent patency rates were also higher in the early RS group than in the late RS group (88.0% vs. 65.4%, p = 0.059). Multivariate analysis identified early RS (OR, 7.187; 95% CI, 1.385-37.306; p = 0.019) and stent patency (OR, 7.291; 95% CI, 1.288-41.277; p = 0.025) as significant factors influencing favorable outcomes.
conclusionRS should be performed at an early stage after failed thrombectomy for ICAS-related LVO.
