Cerebral Venous Thrombosis in COVID-19: A New York Metropolitan Cohort Study

Cerebral Venous Thrombosis in COVID-19: A New York Metropolitan Cohort Study

 

SARS-CoV-2 infection is associated with hypercoagulability. In this retrospective multicenter cohort study the authors sought to evaluate the demographic and clinical characteristics of cerebral venous thrombosis among patients hospitalized for COVID-19 at 6 tertiary care centers in the New York City metropolitan area. Of 13,500 patients with COVID-19, twelve had imaging-proved cerebral venous thrombosis with an incidence of 8.8 per 10,000 during 3 months, which is considerably higher than the reported incidence of cerebral venous thrombosis in the general population of 5 per million annually. There was a male preponderance (8 men, 4 women) and an average age of 49 years (95% CI, 36-62 years; range, 17-95 years). Only 1 patient (8%) had a history of thromboembolic disease. Neurologic symptoms secondary to cerebral venous thrombosis occurred within 24 hours of the onset of the respiratory and constitutional symptoms in 58% of cases, and 75% had venous infarction, hemorrhage, or both on brain imaging. Management consisted of anticoagulation, endovascular thrombectomy, and surgical hematoma evacuation. The mortality rate was 25%. The authors concluded that early evidence suggests a higher-than-expected frequency of cerebral venous thrombosis among patients hospitalized for COVID-19. Cerebral venous thrombosis should be included in the differential diagnosis of neurologic syndromes associated with SARS-CoV-2 infection.
