Flow diversion for acutely ruptured intracranial aneurysms: A single-center retrospective analysis of 30 consecutive cases.

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
objectivesWhen presented with acutely ruptured aneurysms, neurosurgeons may elect to use flow diverters (FDs). However, with the limited evidence concerning their safety and the potential thromboembolic and hemorrhagic complications, their use is extremely infrequent and often quite limited. In this study, we evaluated treatment-related complications, as well as clinical and radiological outcomes, in patients treated with FD stents for acutely ruptured intracranial aneurysms. MATERIALS AND
methodsWe conducted a retrospective review of patients treated with FDs within 15 days postsubarachnoid hemorrhage from 2012 to 2024. Patient demographics, aneurysm characteristics, procedural specifics, along with clinical and imaging follow-ups were assessed.
resultsThe study included 30 patients with a mean age of 55.6 years. Most aneurysms were located within the anterior circulation and were either small or medium-sized. Morphologically, aneurysms were saccular (43.3%), blister-like (40%), and fusiform/dissecting (16.7%). The mean time from rupture onset to treatment was 4.4 days. FD release was successfully achieved in all cases. Posttreatment rebleeding occurred in 10% of patients, ischemic complications in 6.7%, and treatment-related mortality was 6.6%, with an overall mortality of 13.3%. At discharge, 70% of patients achieved a favorable functional outcome. The mean available radiological follow-up period was 26 months, with complete aneurysm occlusion observed in 57.1% of patients at 1 month and in 100% of those available (40%) for follow-up after 1 year.
conclusionsFlow diversion for acutely ruptured aneurysms demonstrates promising outcomes, although careful patient selection and alternative treatment consideration are essential. Future prospective, multicenter studies are needed to validate preliminary findings and optimize treatment protocols for this high-risk patient population.
