Successful Revascularization Using Intravascular Ultrasound-Guided Wiring in Severe Digital Ischemia With Occluded Radial and Ulnar Arteries: A Case Report.
Article in Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 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
With recent advances in endovascular therapy (EVT), treatment of complex peripheral artery disease, especially below-the-knee lesions, has become increasingly feasible using intravascular ultrasound (IVUS)-guided techniques. However, reports on EVT for critical digital ischemia remain scarce because of its rarity. We report a case of successful distal digital revascularization using IVUS-guided wiring. The patient was a 62-year-old man with untreated diabetes who presented with progressive non-healing ulcers on the right second to fourth fingers. Angiography revealed chronic total occlusions of the right radial and ulnar arteries. IVUS-guided parallel wiring enabled guidewire passage from the ulnar artery to the common palmar digital arteries of the second and fourth digits. Balloon angioplasty resulted in adequate distal flow and clinical improvement. This case demonstrates the potential of IVUS-guided EVT in managing complex upper extremity ischemia.
