Abstract Cerebral venous and sinus thrombosis (CVST) can present with a variety of clinical symptoms ranging from isolated headache to deep coma. Prognosis is better than previously thought and prospective studies have reported an independent survival of more than 80\% of patients. Although it may be difficult to predict recovery in an individual patient, clinical presentation on hospital admission and the results of neuroimaging investigations are--apart from the underlying condition--the most important prognostic factors. Comatose patients with intracranial haemorrhage (ICH) on admission brain scan carry the highest risk of a fatal outcome. Available treatment data from controlled trials favour the use of anticoagulation (AC) as the first-line therapy of CVST because it may reduce the risk of a fatal outcome and severe disability and does not promote ICH. A few patients deteriorate despise adequate AC which may warrant the use of more aggressive treatment modalities such as local thrombolysis. The risk of recurrence is low (< 10\%) and most relapses occur within the first 12 months. Analogous to patients with extracerebral venous thrombosis, oral AC is usually continued for 3 months after idiopathic CVST and for 6-12 months in patients with inherited or acquired thrombophilia but controlled data proving the benefit of long-term AC in patients with CVST are not available.
