[Functional testing: a valuable tool in vascular medicine].

Vascular medicine is a multidisciplinary specialty that has been recognized since 2017 through a postgraduate diploma (DES). It is distinguished in particular by the diagnostic autonomy granted to the vascular physician, who prescribes, performs, and interprets functional tests. These include a range of non-invasive examinations, foremost among which is Doppler ultrasound. The major advantage of vascular medicine lies in the immediate correlation between clinical data and imaging, thanks to specific ultrasound training integrated into the DES. Functional tests thus represent an essential asset in the practice of vascular medicine, offering an integrated, dynamic, and personalized approach to patient care.
