Secondary trigeminal neuralgia caused by vertebrobasilar dolichoectasia treated with flow-diverting stent reconstruction: a case report.

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
Vertebrobasilar dolichoectasia (VBD) is a rare clinical condition that occasionally causes secondary trigeminal neuralgia through compression of the trigeminal nerve. Reported treatment methods include oral carbamazepine, microvascular decompression, percutaneous balloon compression, and gamma knife radiosurgery; however, outcomes are often limited, and symptom recurrence is common. Moreover, many of these therapeutic approaches are associated with significant adverse effects. In June 2025, a 66-year-old man presented with VBD-induced secondary trigeminal neuralgia. His diagnosis was confirmed through imaging and clinical studies upon admission. The patient was treated by placing a flow-diverting stent in one vertebrobasilar artery and occluding the contralateral vertebral artery, to reconstruct the blood flow and reduce compression of the trigeminal nerve. The surgical outcome was favorable, with no painful attacks and a visual analogue scale pain score of 0 by postoperative Day 6.
