Non-fasting Glucose Level at Admission Associated with Outcomes in Cerebral Venous Thrombosis

Abstract

Background and Purpose: Cerebral venous thrombosis (CVT) is a rare form of stroke. The objective of this study was to investigate the characteristics, outcomes, and prognostic factors of CVT patients. Methods: This is a five-year retrospective study of CVT patients admitted to our Hospital from April 2016 to April 2021. Medical records were accessed to confirm the diagnosis and obtain the clinical, imaging, laboratory, and treatment data. Further, outcomes of the patients at three months were collected. Binary logistic regression was used to analyse the prognostic factors. Results: Seventy-three patients with CVT were analysed (35.6% male; mean age, 44.3 years). A poor outcome (modified Rankin scale score, 3–6) was 17.8% of patients, and mortality was 10.9%. Factors associated with poor outcomes in all patients with CVT included the duration of presenting symptoms <24 hours (OR: 3.95, 95% CI: 1.13–13.82), age ≥ 50 years (OR: 8.12, 95% CI: 2.16–30.71), a non-fasting glucose level of ≥ 200 mg/dL (OR: 9.58, 95% CI: 1.90–48.25), impaired consciousness (Glasgow coma scale score, 3–8) (OR: 5.63, 95% CI: 1.39–22.81), male sex (OR: 3.73, 95% CI: 1.07–12.98), and brain herniation (midline shift ≥ 5 mm) (OR: 8.75, 95% CI: 1.94–39.57). Headache and use of an oral contraceptive pill were associated with good outcomes in all of the patients. Conclusion: The non-fasting glucose level, a modifiable prognostic factor, exhibited the highest correlation with poor outcomes in CVT patients.
