Embolization of ruptured flow-related aneurysms arising from basilar artery perforators feeding lateral pontine arteriovenous malformations: a case series.

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
Introduction: It is worthwhile to evaluate the safety of endovascular treatment (EVT) for ruptured flow-related aneurysms on basilar artery (BA) perforators that supply lateral pontine arteriovenous malformations (AVMs). Presentation of cases: From July 2017 to March 2024, five patients (1 male and 4 females) aged 54-68 years (mean age, 61.4 years) were enrolled, all presenting with subarachnoid hemorrhage. Angiography identified five lateral pontine AVMs accompanied by six flow-related aneurysms on BA perforators, five of which were ruptured. EVT was successfully performed for all aneurysms using the following approaches: coil embolization alone ( Clinical discussion: Flow-related aneurysms in BA perforators supplying lateral pontine AVMs present unique challenges. The primary concern is brainstem ischemia resulting from occlusion of these perforators. In this case series, occlusion of the BA perforators was not associated with complications. Conclusion: This small series demonstrates that embolization of ruptured flow-related aneurysms on BA perforators that supply lateral pontine AVMs can be safe. A larger series is expected in the future.
