Comprehensive Analysis of Neurologic Complications following Transradial Cerebral Angiography.
Article in AJNR. American journal of neuroradiology, 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 and purposeTransradial access (TRA) for cerebral angiography has become more popular due to fewer complications and greater patient comfort compared with transfemoral access. However, the frequency and nature of neurologic complications linked to TRA remain unclear. This study aimed to determine the incidence of symptomatic neurologic complications after transradial cerebral angiography, identify risk factors, and characterize clinical and imaging features of these complications. MATERIALS AND
methodsWe retrospectively analyzed 1679 consecutive cases of transradial cerebral angiography from a single institution between January 2018 and December 2020. Neurologic complications were defined as any symptomatic changes confirmed by DWI revealing ischemic lesions. A case-control matching method was used to enhance the reliability of the results. Clinical, procedural, and anatomic factors were examined for predictors of neurologic complications.
resultsNeurologic complications occurred in 1.0% (
conclusionsNeurologic complications following transradial cerebral angiography were rare but occurred early in the postprocedural period. The observed ischemic patterns, particularly the right-sided predominance, suggest embolic mechanisms as a potential cause. However, further large-scale, multicenter prospective studies are essential to identify risk factors more clearly and enhance patient safety in this increasingly utilized transradial approach.
