Prospective Epidemiological Study of Upper Limb Venous Thrombosis

Venous thrombosis of the upper limb is one of the manifestations of venous thromboembolic disease. The epidemiology and management of upper limb venous thrombosis is much less well documented than that of lower limb venous thrombosis. The investigators wished to provide epidemiological data concerning upper limb venous thrombosis in the hospital setting. The researchers would like to know the prevalence of this pathology among patients hospitalized in a university hospital center. In order to obtain this prevalence, the investigators wish to carry out a monocentric cross-sectional descriptive study.
