Endovascular straightening of tortuous dissected cervical ICA: a retrospective study in acute stroke.

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
purposeEndovascular treatment of acute symptomatic internal carotid artery (ICA) dissection with severe tortuosity can be technically challenging. Conventional anatomy-preserving stenting in highly tortuous anatomy may result in suboptimal stent-wall apposition and acute vessel re-occlusion. We describe an endovascular straightening technique designed to geometrically correct vessel tortuosity and report preliminary experience compared to conventional treatment.
methodsThis retrospective single-center study included consecutive patients with acute ischemic stroke due to ICA dissection treated endovascularly between 2021 and 2026. Patients received either geometric vessel straightening of the cervical ICA (n = 15) or conventional anatomy-preserving stenting (n = 16). Endpoints were acute stent occlusion (≤ 24 h), 90-day functional independence (modified Rankin Scale 0-2), and symptomatic intracranial hemorrhage (sICH).
resultsBaseline characteristics were balanced between groups. Tandem occlusions were present in 86.7% and 75% of patients, respectively. Acute stent occlusion within 24 h occurred in 1 patient (6.7%) in the straightening group versus 4 patients (25%) in controls (p = 0.333). At 90 days, functional independence was achieved in 86.7% versus 62.5% (absolute difference 24.2%, p = 0.215). sICH occurred in 0% versus 18.8% (p = 0.226). All three patients with sICH developed subsequent stent occlusion.
conclusionIn this retrospective study, endovascular straightening of severely tortuous dissected cervical ICAs appeared technically feasible, with numerically lower rates of acute stent occlusion and sICH and improved functional independence, though differences were not statistically significant. Given the small sample size, findings should be considered exploratory and hypothesis-generating, warranting prospective, adequately powered validation.
