    Asymptomatic Thoracic Migration of a Ventriculoperitoneal Shunt: A Case Report
    (Springer Nature, 2024-09-18) Griffith-Linsley, Jackson; Blackwell, Matthew P.; Gulizia, Dustin J.; Medicine, School of Medicine
    Hydrocephalus is often treated with CSF diversion via ventriculoperitoneal (VP) shunting. We present the unique case of a 33-year-old female with a history of infiltrating astrocytoma and consequent obstructive hydrocephalus necessitating shunt placement. She later presented with non-specific symptoms prompting shunt evaluation. Ultimately, while a cause for her symptoms was not identified, imaging revealed distal catheter migration into the pleural space. The patient remained asymptomatic during two years of follow-up without surgical intervention. This case highlights the potential for asymptomatic distal catheter migration after VP shunt placement and underscores the importance of appropriate monitoring and management once such migration is detected.

    Can the Treatment of Normal-Pressure Hydrocephalus Induce Normal-Tension Glaucoma? A Narrative Review of a Current Knowledge

    Ventriculoperitoneal shunt placement is the most commonly used treatment of normal-pressure hydrocephalus (NPH). It has been hypothesized that normal-tension glaucoma (NTG) is caused by the treatment of NPH by using the shunt to reduce intracranial pressure (ICP). The aim of this study is to review the literature published regarding this hypothesis and to emphasize the need for neuro-ophthalmic follow-up for the concerned patients. The source literature was selected from the results of an online PubMed search, using the keywords "hydrocephalus glaucoma" and "normal-tension glaucoma shunt". One prospective study on adults, one prospective study on children, two retrospective studies on adults and children, two case reports, three review papers including medical hypotheses, and one prospective study on monkeys were identified. Hypothesis about the association between the treatment of NPH using the shunt to reduce ICP and the development of NTG were supported in all reviewed papers. This suggests that a safe lower limit of ICP for neurological patients, especially shunt-treated NPH patients, should be kept. Thus, we proposed to modify the paradigm of safe upper ICP threshold recommended in neurosurgery and neurology into the paradigm of safe ICP corridor applicable in neurology and ophthalmology, especially for shunt-treated hydrocephalic and glaucoma patients.
