Journal Club: Trends in Incidence and Epidemiological Characteristics of Cerebral Venous Thrombosis in the United States.

Cerebral venous thrombosis (CVT) is rare. Early estimations of its incidence were derived from autopsy series and were extrapolated to be around 0.1 to 0.2 patients with CVT per 100,000 per year.1 Recently, a cross-sectional study in the Netherlands and a population-based study in Australia found a much higher incidence of up to 1.6 per 100,000 per year.2,3 Even higher incidences have been reported in the Middle East.4 Wider availability of imaging, technological advances, and a shift in risk factors might explain these differences.2–4
