Resource Utilization After Mechanical Thrombectomy: Is ICU Care Required for All Patients?
Article in Neurocritical care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMechanical thrombectomy (MT) is the standard of care for qualifying patients with acute ischemic stroke (AIS). Minimal postprocedural guidelines often result in patients being admitted to the intensive care unit (ICU) for 24 h, even if they did not receive intravenous thrombolysis (IVT). Whether or not these patients consistently use ICU resources has not been well studied. This study aims to assess the use of ICU resources in post-thrombectomy patients who did not receive IVT.
methodsA single-center retrospective chart review was performed for all patients with AIS who were at least 18 years old and received MT from 2015 to 2022. Patients who received IVT or required ICU-level resources before MT were excluded. ICU-level resources were defined as advanced respiratory support (ARS), neurosurgical intervention, ICU-level infusions (e.g., hypertonic saline, vasoactive, sedating), or interventions requiring ICU-level nursing care. We collected data on patient demographics, stroke characteristics, and the use of ICU-level resources up to 24 h after MT. A multivariate logistic regression model was used to determine the factors associated with ICU resource use.
resultsA total of 239 patients met the inclusion criteria. The median admission National Institute of Health Stroke Scale score was 16. Of these patients, 128 (53.6%) did not require ICU resources in the first 24 h, and 111 (46.4%) did. Vasoactive infusions and ARS were the most used resources (n = 86 [77.4%] and n = 55 [49.5%]). Vasoactive infusions and ARS started during MT were the only statistically significant variables associated with the use of ICU-level resources in the 24 h postprocedure (odds ratio [OR] 2.92, p < 0.001; and OR 2.33, p = 0.009).
conclusionsMost patients who did not receive IVT do not require ICU resources in the first 24 h after MT. Multivariate analysis revealed the only statistically significant factors predicting the need for ICU resources was the use of ARS and vasoactive infusions during MT. These results suggest it may be reasonable to reexamine current monitoring paradigms.
