CEREBRAL VENOUS SINUS THROMBOSIS

From time immemorial, cerebral thrombosis used to be synonymous with arterial thrombosis. But, cerebral venous thrombosis was not uncommon but neurologists and pathologists were not properly oriented regarding cerebral venous thrombosis(CVT) specially because the anatomical knowledge were not updated and nobody actually believed that thrombosis can occur in low velocity capacitance vessels as opposed to the conducting vessels like cerebral arteries. Since the advent of modern investigative modalities like magnetic resonance Imaging (MRI), Computerised Tomography Angiography (CTA) and Magnetic Resonance Venography (MRV) more and more patients are being confidently diagnosed. Occlusions of veins that drain were first published in 1820s. Ribes from France described the first case of dural sinus thrombosis. 1 A 45 year old man developed seizures, headache and delirium who died 6 months later and on autopsy he showed superior sagittal and lateral sinus were thrombosed and the brain showed carcinomatous metastasis. In 1828, Abercrombie described the first case of puerperal sinus thrombosis2 Tonelle 3 published a review on the subject in 1829 which was strengthened by monographs of Kalbag and Woolf in 1967,4 whose contribution on the subject led to dramatic increase in knowledge on the subject. Sir Charles Symonds brought to our knowledge the relatio
