From the Guidelines

Treatment for cavernous sinus thrombosis (CST) typically involves anticoagulation therapy. The use of anticoagulation with heparin or low molecular weight heparin (LMWH) is recommended, regardless of the presence of hemorrhagic conversion, as it has been shown to reduce the risk of death and dependency 1.

Anticoagulation Therapy

  • Heparin: can be used at a dose-adjusted level, with a partial thromboplastin time at least 2 times control 1.
  • LMWH: such as nadroparin, can be used at a dose of 90 anti–Xa U/kg twice daily 1.

Duration of Treatment

The duration of anticoagulation therapy is not well established, but it is recommended to follow the guidelines set for patients with extracerebral deep vein thrombosis (DVT), which includes anticoagulation treatment for 3 months for first-time DVT in patients with transient risk factors and at least 3 months for an unprovoked first-time DVT 1.

Key Considerations

  • Monitoring: close monitoring is essential to adjust treatment as needed and to manage any underlying conditions or potential complications.
  • Supportive Care: management of any underlying conditions and monitoring for complications is crucial in the treatment of CST.

From the Research

Treatment Overview

The treatment for cavernous sinus thrombosis (CST) typically involves a combination of medications and surgical interventions.

  • Antibiotic therapy is a crucial component of treatment, with most patients receiving high-dose intravenous antibiotics 2, 3, 4, 5.
  • Anticoagulation therapy is also commonly used to reduce the risk of further thrombosis and improve outcomes 2, 3, 4, 6.
  • Surgical treatment, such as endonasal sinus surgery or endoscopic drainage of the infected sinuses, may be necessary to remove the source of infection 2, 4.
  • Corticosteroids may be used in some cases to reduce inflammation and swelling 2, 5.

Medication Regimens

  • Intravenous ceftriaxone and metronidazole are commonly used antibiotic regimens for treating CST 2.
  • Anticoagulant drugs, such as heparin or warfarin, may be used to prevent further thrombosis and reduce the risk of complications 3, 6.
  • Vasodilatatory agents and novocaine may also be used as part of the treatment regimen 3.

Surgical Interventions

  • Endonasal sinus surgery or endoscopic drainage of the infected sinuses may be necessary to remove the source of infection and reduce the risk of further complications 2, 4.
  • Surgical treatment may be performed in conjunction with antibiotic and anticoagulation therapy to improve outcomes 2, 4.

Treatment Outcomes

  • The mortality rate for CST has decreased significantly with the use of antibiotic therapy and other treatments 2, 5.
  • However, long-term sequelae, such as neurologic deficits or visual loss, may still occur in some patients 4, 6.
  • Early treatment and prompt identification of CST are essential to reduce the risk of poor outcomes or death 5.
