Impact of Cervical Spine Immobility on Carotid Endarterectomy: A Report of Two Cases.
Article in Cureus, 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
Carotid endarterectomy (CEA) is a well-established revascularization procedure for carotid artery stenosis. While anatomical challenges such as high carotid bifurcation and vascular anomalies are widely recognized, cervical spine immobility due to spinal pathology is infrequently considered during preoperative planning. This report presents two cases in which severe cervical immobility, resulting from diffuse idiopathic skeletal hyperostosis (DISH) and ossification of the posterior longitudinal ligament (OPLL), significantly limited distal exposure of the internal carotid artery (ICA) during CEA. The first case involved a 76-year-old man with symptomatic right ICA stenosis and plaque extending to the C3 level. The second case involved a 75-year-old man with asymptomatic severe left ICA stenosis reaching the C2 level. In both cases, imaging demonstrated extensive DISH and OPLL, and cervical immobility impeded distal ICA exposure despite standard techniques. These cases highlight cervical immobility as an underrecognized factor contributing to technical complexity in CEA and emphasize the importance of assessing the range of motion (ROM) limitations during preoperative evaluation for high cervical lesions. Early identification of such limitations may inform perioperative planning and support individualized treatment selection, including consideration of endovascular alternatives when appropriate.
