hydrocephalus

Question 1

hydrocephalus is

Answer 1

An increase in the quantity of cerebrospinal fluid
(CSF) related to a hydrodynamic disorder.

Question 2

consequences of hydrocephalus

Answer 2

–>dilation of brain cavities
–>intracranial hypertension

Question 3

choroid plexus and spinal sub sub arachnoid space secrete

Answer 3

csf +++

Question 4

what inhibits secretion of csf?

Answer 4

acetazolamide

Question 5

where is csf resorbed

Answer 5

by arachnoid villi++ (depends on hydrostatic pressure)

Question 6

csf circulation order

Answer 6

choroide plexus–>3rd ventricle–>sylvius aqueduct–>4th ventricle–>subarachnoid space

Question 7

what are the main 3 causes of hydrocephalus

Answer 7

-Hyperproduction
- Obstruction of CSF flow
- Faulty resorption

Question 8

what are the consequences of ich

Answer 8

–>Macrocrania in infants
–>visual disorders
–>psychomotor retardation (destruction pf parenchyma)

Question 9

circulation blockage(non communicating hydrocephalus) is due to

Answer 9

non communicating ventricular and arachnoid systems

Question 10

CSF resorption failure (communicating hydrocephalus)

Answer 10

Arachnoid symphysis, thrombosis of venous sinuses, closing of arachnoid villi
Communicating hydrocephalus (Hgie, Infection)

Question 11

what indicates the area of blockage

Answer 11

The number of dilated ventricles points to the area of blockage +++

Question 12

monroe foramen blockage causes

Answer 12

uni or biventricular hydrocephalus

Question 13

Blockage at the level of Sylvius’ aqueduct

Answer 13

tri-ventricular hydrocéphalus

Question 14

Blockage at Magendie’s and Luschka’s foramen

Answer 14

tetra-ventricular hydrocéphalus
