Flexible endoscopy for removal of a migrated fractured ventricular catheter in an adult: A case report and technical note.
Article in Surgical neurology international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Ventricular cerebrospinal fluid shunt is standard care for hydrocephalus but carries risks such as obstruction, infection, and rarely, catheter fracture with migration. Flexible ventricular endoscopy can facilitate safe retrieval for retained positionally labile fragmaents. Case Description: A 55-year-old woman presented with a previous aneurysmal subarachnoid hemorrhage and secondary hydrocephalus. After a shunt malfunction and ventriculitis, imaging showed that the proximal segment of a previous ventricular catheter had migrated from the frontal horn toward the aqueduct of Sylvius. Through a right precoronal approach, a flexible endoscope was advanced, ventricles were systematically inspected to localize the fragment, but without evidence of the migrated catheter. Assuming secondary migration along the roof of the lateral ventricle, the retained catheter was mobilized into sight by continuous irrigation and facilitated into the foramen of Monro, where it was easily captured with endoscopic microforceps and removed under direct visualization without hemorrhage. Conclusion: In selected adults with intraventricular migrated catheter fragments - particularly in the setting of infection and migratory intraventricular hardware located close to critical structures such as the aqueduct - flexible endoscopy provides a minimally invasive option to retrieve foreign bodies safely when trajectories of rigid endoscopy can be limited by the degrees of movement required for optimal visualization.
