Prolonged travel and venous thromboembolism findings from the RIETE registry.

There is a lack of information on clinical risk factors for venous thromboembolism (VTE) development following prolonged traveling. Clinical characteristics and additional risk factors for VTE in travelers were analyzed in RIETE, an ongoing registry of patients with symptomatic, confirmed acute VTE. Of 26,172 patients enrolled in RIETE as of May 2009, 2% developed VTE in association with recent traveling.
