Optimal viewing
These slides are best viewed on a desktop or laptopcomputer running genuine Adobe Acrobat Reader
They have been tested on and are known to work onUniversity classroom PCs
The slides dont work properly on mobile devices, evenwith genuine Adobe Acrobat Readerespecially theembedded 3D models
Navigate through the slides with the Page Up or PageDown keys. Clicking on the headings in the margin or thesmall slide icons below also works.

Controlling the model
Pre-defined views can be chosen from Views in thefloating menu, e.g. the straight sinus
Hold the left mouse button and move the mouse to turnthe model
Rolling the mouse wheel zooms the model
Right click brings up a context menu for Tools->Pan

Limitations
Limitations of this model
The inferior sagittal sinus is not visible (this is usually thecase in MR venography)
There is contamination of the internal carotid arteriesbetween the internal jugular veins and the cavernous sinus

Cerebral venous sinus thrombosis quick facts
Cerebral venous sinus thrombosis is mentioned briefly in theheadache lecture.
Epidemiology and risk factors:
Incidence: RareCaused by infection in the mastiods or orbitOther inherited and acquired thrombophilic states such asoral contraceptives, dehydration, cancer, sepsis,myeloproliferative disorders. Also pregnancy and thepuerperium.More common in younger people due to oral contraceptionbeing a major risk factor
History and examination:
Headaches (in 92% of patients) with strokes, seizures ordecreased conscious stateIntracranial hypertension with nausea, vomiting,papilloedema, visual obscuration

Treatment
Anticoagulation, even if there is haemorrhagic venousinfarction
Outcome
Usually complete recovery with treatmentBut mortality approx 10%
