Multiple isolated spinal aneurysms - A rare condition with uncertain treatment strategies: A case report and literature review.
Review in Brain & spine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Isolated spinal aneurysms (iSAs) are rare, with an uncertain natural history and no established treatment guidelines. Multiple iSAs are even more uncommon, complicating treatment decisions. Methods: This study reports a case of a ruptured radiculo-pial artery aneurysm in a patient with multiple iSAs, treated with surgical excision, assisted by intraoperative neurophysiological monitoring (IONM). Further, we review and analyze all previously reported cases of multiple iSAs. Results: A 67-year-old woman with spinal subarachnoid hemorrhage and spinal cord compression due to a ruptured radiculo-pial artery aneurysm was treated surgically. Digital subtraction angiography (DSA) showed three spinal aneurysms. Intraoperative indocyanine green video-angiography (ICG-VA) revealed an aneurysm contributing to the left posterior spinal artery. The aneurysm was excised after proximal inflow occlusion under IONM. The other aneurysms spontaneously regressed, and the patient had a good functional outcome. Through a systematic literature review, we analyzed 13 multiple iSAs including our case, involving 34 aneurysms in total. Conclusions: There is no standardized treatment approach for multiple iSAs. These aneurysms are often fusiform and clustered in contiguous metameric regions. They can be classified into flow-related and wall-weakening aneurysms. Surgery offers definitive treatment for ruptured iSAs and relieves spinal cord compression. Due to the common fusiform shape, parent vessel sacrifice may be necessary, and should include IONM and ICG-VA to minimize complications. Conservative treatment is viable as spontaneous regression often occurs.
