2

[IVT]: infarction in specific venous territory is found in dural venous or cortical vein thrombosis

cortical vein

3

[IVT]: Focal stroke like signs are seen in dural venous or cortical veins thrombosis.

cortical vein thrombosis

4

[IVT]: what sign is commonly found in cortical vein thrombosis cf. arterial stroke.

Seizures

5

[IVT]: What character of headache is associated with IVT

thunderclap

6

[IVT]: what is the most common sinus to be affected in dural thrombosis

Sagittal sinus thrombosis

7

[IVT]: what is the 2nd most common sinus to be affected in dural venous sinus thrombosis

Transverse

8

[IVT]: what is the 2nd most common sinus to be affected in dural venous sinus thrombosis

Transverse

9

[IVT]: what is the time course progression of symptoms in dural sinus thrombosis

days - weeks

10

[IVT]: what would be seen on fundoscopy

papilloedema

11

[IVT]: what would be seen on fundoscopy

papilloedema

12

[IVT]: thrombosis in a dural venous sinus can result in an extension of thromboses into the .... veins, but rarely vice versa.

cortical

13

[IVT]: Where is the thrombosis likely to be if the vision is impaired?

sagittal sinus

14

[IVT]: Mastoid pain + CNS signs indicates thrombosis where?

transverse sinus

15

[IVT]: which sinus is affected if there are cerebellar signs

Sigmoid

16

[IVT]: which sinus is affected if there are lower cranial nerve palsys

Sigmoid

17

[IVT]: What is Gradenigos syndrome? (4)

5th CN palsy
6th CN palsy
Retro-orbital pain
temporal pain

18

[IVT]: thrombosis where causes Gradenigos syndrome

inferior petrosal sinus (dural)

19

[IVT]: oedematous eyelids, proptosis, painful opthalmoplegia, conjuctival oedema (chemosis) is likely due to thrombosis in which sinus?

Cavernous

20

[IVT]: facial pustules/folliculitis can spread and causes thrombus in which sinus

Cavernous

21

[IVT]: Do cortical vein thrombi usually occur in isolation or in conjunction with dural thrombus

conjunction

22

[IVT]: Do cortical vein thrombi usually occur in isolation or in conjunction with dural thrombus

conjunction

23

[IVT]: focal seizures or focal deficits are likely due to thrombus in which system - dural or cortical

cortical

24

[IVT]: if the patient presents with a thunderclap headache what must you exclude

SAH

25

[IVT]: if there is a raised CSF opening pressure on LP + headache what system is likely to be causing this (with SAH excluded)

Cortical vein thrombosis

26

[IVT]: What Ix would you carry out?

CT/MRI venography (NB: the block vessel will not show up)

27

[IVT]: Mx?
