A small majority of patients were female (52.6%) and the mean age of the cohort was 52.9 years (SD 15.8 years). A majority of intracranial lesions were intraaxial (59.3%). The incidence of VTEs was 3.0% and the rates of deep venous thromboses and pulmonary emboli were 2.3% and 0.9%, respectively. On multivariate analysis, increasing patient age (unit OR 1.02, 95% CI 1.00\u20131.05; p = 0.018), history of VTE (OR 7.26, 95% CI 3.24\u201316.27; p &lt; 0.001), presence of motor deficit (OR 2.64, 95% CI 1.43\u20134.88; p = 0.002), postoperative intracranial hemorrhage (OR 4.35, 95% CI 1.51\u201312.55; p &lt; 0.001), and prolonged intubation or reintubation (OR 3.27, 95% CI 1.28\u20138.32; p &lt; 0.001) were independently associated with increased odds of a VTE. There were 192 patients who received VTE chemoprophylaxis (11.8%); the mean postoperative day of chemoprophylaxis initiation was 4.6 (SD 3.8). The incidence of VTEs was higher in patients receiving chemoprophylaxis than in patients not receiving chemoprophylaxis (8.3% vs 2.2%; p &lt; 0.001).
