Insights

Anticoagulation therapy significantly reduces mortality in adult patients with septic cavernous sinus thrombosis (SCST). This review suggests heparin is a common initial treatment, with prolonged use potentially improving outcomes.

Area of Science:

  • Medical research
  • Clinical treatment
  • Systematic review and meta-analysis

Background:

  • Septic cavernous sinus thrombosis (SCST) is a rare but severe condition with high mortality and morbidity.
  • The efficacy of anticoagulation in treating SCST is not well-established due to limited evidence.

Purpose of the Study:

  • To investigate the association between anticoagulation and mortality in patients with cavernous sinus thrombosis originating from sinusitis.
  • To identify the types and duration of anticoagulation therapies employed in SCST cases.

Main Methods:

  • A systematic review and meta-analysis adhering to PRISMA guidelines.
  • Inclusion of adult patients (≥18 years) diagnosed with SCST, confirmed by objective methods.
  • Data extraction from 72 articles comprising 110 patients, with logistic regression for confounding factor adjustment.

Main Results:

  • A significantly lower mortality rate was observed in patients receiving anticoagulation (3.3% vs. 18%, p=0.022).
  • The adjusted odds ratio for mortality in the anticoagulation group was 0.067 (95% CI: 0.009–0.475).
  • Heparin was the most frequent initial anticoagulant, with one-third of patients treated for three months.

Conclusions:

  • Anticoagulation therapy shows a strong potential to improve survival rates in adult patients diagnosed with SCST.
  • Careful consideration of hyperglycemia is recommended before initiating anticoagulation in SCST patients.
