Flexible ventricular endoscopy can facilitate safe retrieval for retained positionally labile fragmaents.<\/jats:p>\n <\/jats:sec>\n \n Case Description:<\/jats:title>\n 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.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n In selected adults with intraventricular migrated catheter fragments \u2013 particularly in the setting of infection and migratory intraventricular hardware located close to critical structures such as the aqueduct \u2013 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.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_1390_2025","type":"journal-article","created":{"date-parts":[[2026,4,25]],"date-time":"2026-04-25T08:55:40Z","timestamp":1777107340000},"page":"233","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Flexible endoscopy for removal of a migrated fractured ventricular catheter in an adult: A case report and technical note"],"prefix":"10.25259","volume":"17","author":[{"given":"Jonathan","family":"Ramos-Escalante","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo","family":"Garc\u00eda-Iturbide","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ures Eduardo","family":"Campos-Rodriguez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor Ramzes","family":"Chavez-Herrera","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emmanuel","family":"Cant\u00fa-Ch\u00e1vez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"S.
