What’s inside
7 sections · 50 slides
Why Endoscopy for Deep Tumors
- The problem: tumors buried in the fluid spaces
- The idea: a lit camera on a narrow tube
- Why surgeons reach for it
- What the endoscope buys you
Choosing the Right Patient
- Four things to weigh before committing
- Size: small and solid is ideal
- Consistency: soft yields, firm fights back
- Vascularity: bloody tumors cloud the view
- Ventricle size: room to work matters
- The numbers that guide the case
The Toolkit: Choosing an Endoscope
- Four scopes, four trade-offs
- Rigid lens scope: the workhorse
- Neuroendoscopes for ventricular surgery
- Flexible fiberoptic scope: the contortionist
- Rigid mini scope and video-endoscope
- Holding the scope: fixed arm or free hand
- Scope selection at a glance
Planning the Entry Point
- General rules for picking a side
- Anatomy sets the target
- Entering the lateral ventricles
- Burr-hole entry sites and achievable trajectories
- Entering the third ventricle
- Contralateral versus ipsilateral trajectory
Inside the Ventricle: The Operation
- Irrigation: keeping the water clear
- Hemostasis, part 1: find the bleeder first
- Hemostasis, part 2: the tools to stop it
- Sizing the burr hole
- How burr-hole size limits endoscope movement
- Tumor biopsy: sampling under direct vision
- Endoscopic anatomy of the lateral ventricle
- Tumor resection: taking the whole lesion
- Combined third ventriculostomy and tumor resection
- Endoscopic tumor resection, continued
Approach by Ventricle
- Lateral and third ventricle approaches
- Reaching the fourth ventricle
- Fourth ventricle: mind the aqueduct
After the Operation
- Postoperative management
- Key takeaways
- Why is a solid tumor over 2 cm usually unsuited to endoscopic resection, yet a large cystic one may still qualify?
