1: Microneurosurgery Of Brain Tumors

Question 1

Main groups of brain tumors

Answer 1

abnormal mass of tissue -> cells grow/multiply uncontrollably

• primary (glial/non-glial) (benign/malignant)
• metastatic

Question 2

Current challenges:

Answer 2

Anatomy
• Macro: limited resolution of in vivo-anatomy
• Micro: not available in-vivo in human

Connectivity
• Macro: not sufficiently reliable in-vivo
• Micro: non available in-vivo

Function
• Lesional: in human only “observational”, non reproducible, non available surgical model
• Stimulation: limited spectrum, reliable model?

Question 3

2 schools

Answer 3

• REMOVE ONLY THE TUMOR (dont know what function there is, cisternal navigation)
• IF THERE IS NO FUNCTION, TAKE IT OUT (offene OP, wenn sich nichts ändert weiter vordringen)

Question 4

Advanced Preoperative Imaging

Answer 4

• Microscopy & Microneurosurgery
• Cisternal navigation (durch Gänge die es schon hat)
• Endoscopy
• Neuronavigation
• Intraoperative Ultrasound -> realtime visualizatio
• Intraoperative MRI
• Intraoperative Neurophysiology (Neurostimulation)
• Intraoperative Fluorescence
