Complications and long-term outcomes after endovascular treatment of basilar trunk aneurysms.
Article in Frontiers in neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: Basilar trunk aneurysms (BTAs) are rare and challenging to treat, with a high complication rate. This study aimed to analyze and evaluate the complications and long-term outcomes associated with endovascular treatment (EVT) of BTAs and identify risk factors for post-procedural complications and unfavorable clinical outcomes. Methods: This retrospective, observational cohort study included 90 patients (92 BTAs) treated with EVTs from January 2011 to April 2023. Factors associated with post-procedural complications and unfavorable clinical outcomes were analyzed. Results: All 90 patients (92 aneurysms) were successfully treated, of which 63 (68.5%) aneurysms were small, 26 (28.3%) were large, and 3 (3.3%) were giant; 23 (25%) were saccular, and 69 (75%) were fusiform and/or dissecting. A total of 36 (40.0%) patients were admitted with ruptured aneurysm. The median follow-up duration was 51.0 months (IQR 21.0-3.0). The favorable clinical outcome rate was 75.6% (68/90). The overall complication rate was 33.33% (30/90), with ischemic and hemorrhagic complications occurring in 25.6% (23/90) and 2.2% (2/90) of cases, respectively. The mortality rate was 8.9% (8/90). Unilateral vertebral artery sacrifice ( Conclusion: EVT for BTAs appears feasible and yields favorable clinical outcomes at the last follow-up, with reasonable cumulative survival rates at 1, 3, and 5 years. However, clinicians should be vigilant for procedure-related complications, particularly ischemic complications, which may lead to poor outcomes or death.
