When the area of intracranial venous sinus thrombosis is small, it will not cause obvious clinical manifestations, and the situation is not serious, usually only need to actively treat the underlying diseases, such as hypertension, diabetes mellitus, hyperlipidemia, etc., and at the same time, with the use of anticoagulant drugs, such as heparin, warfarin, etc., to control the further development of intracranial venous sinus thrombosis. If the intracranial venous sinus thrombosis involves a larger part and scope, it can cause serious symptoms such as dizziness, headache, seizure, consciousness disorder, etc. At this time, the condition is more serious and active treatment measures should be taken. Treatment methods include heparin anticoagulation and interventional thrombolytic therapy.
