Rupture risk and outcomes of giant aneurysms in pediatric patients: a multi-institutional case series and systematic review.

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
objectiveGiant aneurysms in pediatric patients are vascular lesions that can cause significant neurological morbidity and mortality. Their rarity has precluded large cohort studies to inform their management. The objective of this study was to understand the clinical course and outcomes of giant aneurysms in pediatric patients.
methodsThe authors performed a multi-institutional cohort study of cases from Boston Children's Hospital and Barrow Neurological Institute, as well as a systematic review and pooled cohort analysis of previously reported cases using descriptive statistics and multivariate regression modeling.
resultsFifteen patients were included in the multi-institutional cohort, and an additional 88 patients were included from 14 series, yielding 103 patients within the pooled cohort. Among the pooled cohort, the most common aneurysm locations were in the middle cerebral artery (36%), internal carotid artery (27%), vertebral artery (11%), and vertebrobasilar junction (8%). Within 69 cases containing radiographic data in the analysis, 38% of aneurysms were saccular. Twenty-eight cases presented with aneurysm rupture (28%), including 0% of cavernous carotid aneurysms, 26% of other anterior circulation aneurysms, and 44% of posterior circulation aneurysms (p = 0.003). In multivariate analysis, posterior circulation location (OR 2.66, 95% CI 1.03-6.86) and younger age (OR 0.90 per year, 95% CI 0.81-1.00) were associated with aneurysm rupture presentation. Most cases were treated (97%) rather than observed (3%). The mortality rate was 3% for unruptured aneurysms and 18% for ruptured aneurysms. A favorable neurological outcome occurred in 80% of unruptured aneurysm cases and 54% of ruptured cases. In multivariate analysis, unruptured aneurysm presentation (OR 3.74, 95% CI 1.24-11.29) and endovascular treatment modality (OR 5.05, 95% CI 1.56-16.29) were associated with a favorable outcome.
conclusionsGiant aneurysms are rare entities in pediatric patients that are unlikely to be discovered incidentally and usually merit treatment. Most patients survive with good neurological outcome, even in ruptured aneurysm cases. These data reveal that posterior circulation location and younger age are risk factors that correlate with an increased risk of aneurysm rupture.
