Summary
A novel pinless, frameless stereotactic system enables simultaneous endoscopic and image-guided navigation in infants. This technique improves the management of complex intraventricular lesions in young children, avoiding risks associated with rigid fixation.
Area of Science:
- Pediatric Neurosurgery
- Minimally Invasive Neurological Surgery
- Neuroradiology
Background:
- Infants and young children often present with intraventricular and periventricular lesions.
- Endoscopic treatment is valuable but limited by complex cysts or obscured anatomy.
- Existing frameless stereotaxy requires rigid cranial fixation, posing risks for infants.
Observation:
- Two infants with complex arachnoid cysts and hydrocephalus were treated.
- One infant had macrocephaly and bulging fontanelle; the other had post-hemorrhagic hydrocephalus with multiloculated ventricles.
- Both patients presented with significant neurological symptoms and imaging findings indicating complex ventricular pathology.
Findings:
- A pinless, frameless stereotactic assembly was used for simultaneous endoscopic and image-guided navigation in infants.
- This method allowed for precise tracking of instruments and identification of target areas for intervention.
- The technique facilitated fenestration, biopsy, and catheter insertion within the ventricular system.
Implications:
- Simultaneous image-guided and endoscopic neuronavigation offers advantages for complex intraventricular lesions in infants.
- This approach may reduce procedure-related morbidity compared to methods requiring rigid cranial fixation.
- It enhances the interpretation and management of challenging neurosurgical cases in pediatric patients.
