TO THE EDITOR:
The article by Prandoni and colleagues (1) showed an association between residual venous thrombosis and recurrent venous thromboembolism. As demonstrated in several studies, DVT appears to be multifactorial (2). Therefore, the authors' classification of patients is confusing. They divided patients into three main categories: thrombophilia, secondary thrombosis, and idiopathic thrombosis. This does not take into consideration the fact that in thrombophilia, a triggering event (for example, secondary thrombosis) often contributes to the disease (3). Furthermore, 15% of Prandoni and colleagues' patients were not tested for thrombophilia. It would be useful for the medical community and ongoing or future studies to adopt a consensus classification for the description of the subpopulations; this would allow us to extrapolate results from one study to another.
