Early change and new onset of vascular pathology in cervical artery dissection: implications for surveillance.
Article in European stroke journal, 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
introductionAntithrombotic therapy is central to stroke prevention after spontaneous cervical artery dissection (sCAD), but its efficacy may depend on the underlying vascular morphology. We examined the temporal course of vascular changes after sCAD. PATIENTS AND
methodsConsecutive patients with first-time sCAD underwent prospective serial duplex sonography for up to 10 years. In this retrospective cohort analysis, pathology change was defined as recanalisation of an occluded artery or progression from stenosis to occlusion. New pathology resulting from dissection recurrence was considered if an occlusion occurred in the presence of pre-existing stenosis or vice versa.
resultsIn total, 159 patients (83 men; mean age 44.8 years) with first-time sCAD were followed-up starting 1.3 days (median) after symptom onset. Bilateral dissections occurred in 6 patients and recurrent dissections in 26 arteries, resulting in follow-up of 191 arteries (108 internal carotid, 83 vertebral). Recanalisation occurred in 40/80 occluded arteries (cumulative rate 70.4%), whereas progression to occlusion occurred in 9/109 stenosed arteries (10.0%). All changes except one (recanalisation) occurred within 4 months. Recurrent dissection occurred within 6 weeks in 20 patients (14.7%) and between 2 and 7 years in 7 patients (13.7%). Overall, 62 vascular changes or new pathologies were observed in 50 patients (31.4%), with 42 occurring within the first 6 weeks.
conclusionsUnder intensive surveillance, vessel morphology after sCAD is highly dynamic during the early phase, with frequent recanalisation and recurrent dissection. Structured early vascular follow-up may be important if evolving vessel morphology is to guide future individualised antithrombotic treatment strategies.
