Management of Post-Stroke Cold Sensations: A Case Study on Sympathetic Nerve Ablation.
Article in The American journal of case reports, 2025. 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
BACKGROUND Stroke is a leading cause of mortality worldwide and often results in complex sequelae. Peripheral circulation disorders in paralyzed limbs are particularly challenging, presenting as persistent cold sensations and cold-induced pain that severely impair patients' quality of life. This report presents an innovative approach to managing refractory post-stroke limb coldness and pain using computed tomography (CT)-guided sympathetic nerve radiofrequency ablation. CASE REPORT We present the case of a 65-year-old woman with hemiplegia in her left extremities following a cerebral infarction 1 year earlier. Despite standardized treatment, her condition worsened after 6 months, with increased spasticity, cold-induced pain, and a significant drop in temperature in the left limbs. To address these issues, CT-guided radiofrequency ablation of the sympathetic nerve at the fourth thoracic vertebra and the third lumbar vertebral body was performed at 75°C for 3 min. The procedure significantly improved the peripheral perfusion index, increased palm and foot temperature, and reduced pain. Magnetic resonance imaging revealed improved cerebral infarction and enhanced brain function in temperature-related regions. Ethical approval and patient consent for publication were obtained. CONCLUSIONS CT-guided radiofrequency ablation of the thoracic and lumbar sympathetic nerves effectively alleviates post-stroke peripheral circulation disorders, improves limb temperature, and enhances collateral circulation. This report underscores the importance of awareness and early intervention for such post-stroke complications in patients.
