  1. CEREBRAL VENOUS THROMBOSIS

  2. HISTORY • 1828, Abercrombie • 1873, Parrot • 1888, Sir William Gowers • 1915, Holmes and Sargent • Quincke, Meningitis

  3. MAJOR VENOUS DRAINING PATHWAYS OF THE CRANIUM

  4. DURAL SINUSES • Superior sagittal sinus • Inferior sagittal sinus • Straight sinus • Torcular Herophili(sinus confluens) • Transverse sinus • Sigmoid sinus • Occipital sinus • Inferior petrous sinus • Superior petrous sinus • Cavernous

  5. SUPERFICIAL CORTICAL VEINS • Sylvian veins • Trolard’s veins and Labbe’s veins • Frontal ascending/ descending cortical veins • Occipital cortical veins • Sphenoparietal vein

  6. DEEP CEREBRAL VEINS • Subependymal veins • Thalamostriate veins • Septal veins • Internal cerebral veins • Basal vein( Rosenthal’s vein) • Galen’s vein • Anterior pontomesencephalic veins • Precentral cerebellar vein • Superior and inferior vermian veins

  7. DURAL VEINS • Meningeal veins • Emissary veins(connection between sinus and scalp)

  8. SCALP VEINS • Occipital veins • Temporal veins

  9. CERVICAL VEINS • Jugular bulb • Internal jugular vein • External jugular vein

  10. AETIOLOGY • Changes in the vessel Wall • Changes in the blood flow • Changes in the coagulability of blood

  11. AETIOLOGY(GROUP) • Endocrinological disturbances:Oral contraceptives, Pregnancy • Haematological/immunological abnormalities: Protein C, APLA Syndrome • Connective tissue and other inflammatory disorders:Systemic lupus erythematosus (SLE) • Neoplastic: Cerebral metatases • Infective: Endocarditis • Miscellaneous:High altitud, cardiac failure

  12. Neurological Features of CVT

  13. Neurological Features of CVT

  14. Frequency of involvement of the various sinuses in CVT

  15. CLINICAL FEATURES • Lateral Sinus Thrombosis • Cavernous Sinus Thrombosis • Superior Sagittal Sinus Thrombosis • Thrombosis of the other dural sinuses

  16. INVESTIGATIONS • Computerized tomography • Magnetic resonance imaging • Angiography • Lumbar puncture • Aetiological diagnosis
