Intracranial venous sinus non-suppurative thrombosis treatment includes etiologic treatment, antithrombotic treatment and symptomatic treatment. 1. Etiologic treatment: autoimmune diseases such as systemic lupus erythematosus and leukemia can be treated with hormone therapy.) For hematologic diseases, appropriate treatment should be given. For those with increased blood viscosity, hydroxyethyl starch is used to dilate and reduce blood viscosity. 2. Antithrombotic treatment (1) Anti-coagulation therapy: the earlier the better, it can significantly reduce the mortality rate and improve the prognosis of patients. Low molecular heparin and warfarin can be used. (2) Thrombolytic therapy: Atriplasmin can be used for intravenous thrombolysis, but there is no evidence to show that its treatment is better than anticoagulation, and it can be used as the second choice for patients who continue to deteriorate after anticoagulation. It can be used as the second choice after anticoagulant therapy. Local thrombolysis with vascular intervention is feasible. (3) Interventional therapy: vascular intervention, intraventricular catheter mechanical thrombolytic therapy and angioplasty. 3. Symptomatic treatment (1) Lowering cranial pressure treatment: Mannitol, glycerol fructose, furosemide, albumin and other drugs can be applied. If the drugs are ineffective, the corresponding surgical treatment should be considered, such as ventricular drainage and venous bypass surgery. (2) Antiepileptic treatment can be carried out when there are epileptic seizures. If the diagnosis of intracranial venous sinus non-suppurative thrombosis is confirmed, it is recommended to standardize the treatment under the guidance of doctors.
