Comparison of Optic Nerve Sheath Diameter Measured by Ultrasonography Before and After Ventriculoperitoneal Shunt Surgery in Adult Patients With Hydrocephalus

Summary

Hydrocephalus is a disturbance of cerebrospinal fluid production, flow and absorption leading to intracranial hypertension. Assessment of the change in intracranial pressure after ventriculoperitoneal shunt surgery is important in guiding appropriate postoperative management. The optic nerve sheath diameter measured using ultrasonography has been verified as a non-invasive indicator of intracranial hypertension in various clinical studies. The investigators hypothesized that a change in optic nerve sheath diameter detected through ultrasonography could help ascertain a reduction in intracranial pressure following ventriculoperitoneal shunt surgery in adult patients without the risk of serious complications.

Conditions

  • Hydrocephalus

Interventions

DEVICE

ultrasonographic measurement of optic nerve sheath diameter

A thick layer of gel is applied on the upper closed eyelid. The linear 7.5-MHz ultrasound probe is then placed in the gel, without exerting pressure on the eye. Three measurements are taken for each optic nerve in the transverse plane, with the probe being horizontal. The final ONSD is the mean of these measurements.
