Hi I am preparing for viva for neurosurgery exam and I am going to give you a topic then you will tell me how this pt will present and what age of pt. Will be and you will also tell me approach to pt. For clinical diagnostic and therapeutic way and anything u tell me options like when to do which surgery brief about that surgery and if you tell me about drug tell me Moa of drug and special points of drug and specific doses of drug and if you tell me investigation tell me indications of Ix and also positive findings also tell me if any score in that pt so in crux you will tell me demography, clinical features, radiological and pathological ix and mx approach and try to add images if possible and if follow up then how frequent and with which modality and try to use standard books also give any classification is there The topic is hydrocephalus and ice monitoring and tell about all types of hcp
hydrocephalus CT scan ventricular enlargement
ICP waveform Lundberg A B C waves intracranial pressure monitoring
normal pressure hydrocephalus NPH MRI ventriculomegaly callosal angle
endoscopic third ventriculostomy ETV procedure floor of third ventricle
-
All types of HCP — Non-communicating, Communicating, NPH (Hakim-Adams), Ex vacuo, External (benign infantile), Arrested/Compensated, and Overproduction type — each with age/demographics, causes, and clinical features
-
Clinical presentations by age group — Infant (setting sun sign, macrocephaly, fontanelle bulge) vs. Child (papilledema, morning headache) vs. Adult/NPH ("Wet, Wobbly, Wacky")
-
Investigations — CT (Evans Index, bicaudate index, periventricular lucency), MRI (callosal angle, DESH, flow voids for ETV), LP tap test for NPH, CSF analysis
-
Management — Stepwise: emergency medical (mannitol, dexamethasone, acetazolamide with full MOA and doses) → surgical (EVD at Kocher's point, VP shunt with valve types and complications including slit ventricle, ETV with exact technique and Fogarty balloon, VA shunt)
-
ICP Monitoring — Monro-Kellie, normal values, P1/P2/P3 waveforms, Lundberg A/B/C waves, all device types with pros/cons, PRx index
-
Scores — Evans Index, Callosal Angle, ETVSS, Hunt-Hess, Modified Fisher, GCS thresholds
-
Follow-up protocols — by modality and frequency for each surgical approach
Hi I am preparing for neurosurgery and I want few things from you 1 all important neurosurgeons, few photos of them and their main contribution 2. First give me brief about all imp imaging types like ct t1 t2 mri etc also mr spectroscopy as much as types possible and then u will also give one by one image of specific findings imp in neurosurgery 2to3 pics of each with descriptions 3 instruments used in neurosurgery with pics and descriptions as much as possible and from simple to complex including endoscopes and microscopes also 4 all imp trials in neurosurgery with brief descriptions 5 neuropharmacology with antibiotics used in neurosurgery anti epileptics in neurosurgery anti edema agents , chemotherapy agents in neurosurgery and give me drug class, mechanism of action, side effects, special points and try to add as much as images overall and also use standard books
