1 · What the graph read from it

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.

2 · The registry

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

backgroundTransradial vertebral artery (VA) stenting is an effective, and relatively safe treatment for symptomatic extracranial VA stenosis-the main cause of posterior circulation ischemia. Still, rare non-target anterior circulation cerebral embolisms can occur intraoperatively. CASE PRESENTATION: A 63-year-old male with prior cerebral infarction (NIHSS score 0, mRS score 1) presented with recurrent dizziness. Pre-admission CTA imaging confirmed severe (> 70%) bilateral VA ostial stenosis. The patient underwent right transradial VA stenting. Ten minutes post-procedure, he developed altered consciousness, mixed aphasia, and right hemiplegia (NIHSS score 16). Angiography confirmed acute occlusion in the M2 segment of the left middle cerebral artery (MCA). Mechanical thrombectomy was attempted but terminated due to severe vascular tortuosity, with no recanalization achieved. Immediate postoperative CT revealed contrast extravasation (CE) in the left frontoparietal sulci, rather than intracranial hemorrhage. The patient received tirofiban, dual antiplatelet therapy, and early rehabilitation. By discharge on day 7, he had achieved partial recovery (NIHSS score 9, mRS score 4).

conclusionDespite its extremely low incidence, the risk of anterior circulation cerebral embolism persists during transradial posterior circulation interventions. Gentle manipulation and emboli monitoring may mitigate this risk. Intraoperative neuromonitoring and rapid imaging are critical, and precise diagnosis and treatment can facilitate functional recovery.
