Mother-Daughter Ventricular Endoscopy: A Technical Note and 2-Dimensional Video

Area of Science:

• Neurosurgery
• Minimally Invasive Surgery
• Medical Technology

Background:

• Rigid endoscopes offer excellent visualization but are too large for narrow ventricles.
• Flexible endoscopes are small but lack the handling and visualization of rigid scopes.
• Existing endoscopic techniques face limitations in navigating confined spaces within the brain.

Observation:

• A novel "mother-daughter" endoscopy technique was employed.
• A flexible 1-mm fiberoptic endoscope was introduced through a larger rigid endoscope.
• This allowed visualization and intervention within the cerebral aqueduct.

Findings:

• The mother-daughter approach facilitated safe exploration of a restenosed aqueduct.
• It enabled precise fenestration and accurate stent placement in a challenging case.
• The technique improved safety and expanded possibilities in complex ventricular surgery.

Implications:

• Mother-daughter endoscopy enhances safety in high-risk neurosurgical procedures.
• It allows for improved navigation and intervention in small or occluded spaces.
• This technique broadens the application of endoscopic surgery in treating hydrocephalus and other ventricular conditions.
