Circannual variability of venous thrombosis has been reported since 1939, but there is no definitive determination of whether it really exists. Although a recent meta-analysis on this topic, including 35 000 patients with venous thrombosis, has recently been published , and showed a similar existence of a seasonal variability in venous thrombosis as for arterial cardiovascular disease , there are some issues that preclude whether this meta-analysis found a true association between seasonal variability in the incidence of venous thrombosis. © 2012 International Society on Thrombosis and Haemostasis.
