Cerebral venous thrombosis in elderly patients

Background and purpose We aimed to report the characteristics of cerebral venous thrombosis (CVT) in elderly people (aged ≥65 years). Methods This multicenter retrospective cohort included elderly patients hospitalized for a first CVT in nine Paris–Ile‐de‐France hospitals between 2011 and 2021. The estimated incidence was compared to CVT recorded by the French health insurance data system. Lariboisière Hospital's CVT registry allowed comparisons of our elderly cohort with individuals younger than 65 years. Results One hundred fourteen patients were included in this study (mean age = 74.2 years, range = 65–93, 61% female). The CVT annual incidence in Ile‐de‐France was 5.9–7.1 per million elderly individuals versus 8.5 per million nationwide. Headaches and focal deficits were the most common initial clinical features (50% and 51%, respectively), followed by seizures and confusion (40% and 27%). Treatment included anticoagulation (93%) and, rarely, endovascular procedure (2%) or craniectomy (1%). Compared with adult patients aged
