Denouement and Discussion
Poststrangulation Cerebral Sinovenous Thrombosis
Cerebral sinovenous thrombosis has been classified as being either septic or aseptic. Septic thrombosis is secondary to inflammation involving the intracranial venous system, as in meningitis and encephalitis, or from intracranial spread from mastoiditis or sinusitis. Aseptic causes are many (eg, polycythemia vera, trauma, strangulation, dehydration, congenital heart disease, collagen vascular disease, and oral contraceptive use), and rarely does this condition occur as an isolated
