Magnetic resonance imaging-directed stereotactic endoscopic third ventriculostomy

Area of Science:

• Neurosurgery
• Medical Imaging
• Neurology

Background:

• Obstructive hydrocephalus often requires intervention.
• Third ventriculostomy is a preferred procedure for certain hydrocephalus cases.
• Existing techniques for third ventriculostomy vary.

Purpose of the Study:

• To describe a novel technique for stereotactic third ventriculostomy using MRI guidance.
• To evaluate the efficacy and safety of this MRI-guided approach.

Main Methods:

• Utilized magnetic resonance imaging (MRI) for precise anatomical landmark identification (foramen of Monro, interpeduncular cistern).
• Employed a rigid endoscope for continuous direct visualization during the procedure.
• Integrated the MRI guidance with the Cosman-Roberts-Wells stereotactic apparatus.
• Performed the procedure on three patients with acquired obstructive hydrocephalus.

Main Results:

• Successful performance of stereotactic third ventriculostomy in all three patients.
• Achieved clinical improvement in all treated patients.
• Avoided the need for extracranial shunting in the patient cohort.

Conclusions:

• MRI-guided stereotactic third ventriculostomy is a viable and effective treatment for obstructive hydrocephalus.
• This technique offers accurate navigation and direct visualization, leading to positive clinical outcomes.
• The procedure eliminates the necessity for shunting in select patients, reducing potential complications.
