Trans-reservoiral ventriculography (TRV).

Area of Science:

• Neurosurgery
• Neuroradiology
• Medical Imaging

Background:

• Ventriculography is a key diagnostic imaging technique in neurosurgery.
• Existing methods may have limitations in safety or efficacy for specific applications.
• Monitoring brain tumor progression and treatment response requires precise visualization.

Observation:

• A novel water-soluble contrast medium was developed for enhanced safety.
• Percutaneous injection through a shunt flushing reservoir enables a new ventriculography approach.
• Twelve clinical cases demonstrated the feasibility and utility of this method.

Findings:

• Trans-reservoiral ventriculography (TRV) proved useful in observing brain tumor courses.
• The technique is applicable after both surgical and non-surgical treatment interventions.
• The new contrast medium exhibited a high safety profile.

Implications:

• TRV provides a valuable tool for neuro-oncology and post-treatment patient management.
• This method can improve the assessment of therapeutic efficacy for brain tumors.
• Further research may expand the applications of TRV in neurological diagnostics.
