[Venous endoscopy].

The miniaturization of endoscopic equipment now allows exploring the superficial venous system and visualizing the endovein in situ and in vivo. This type of venous endoscopy is an ambulatory procedure, performed during a simple outpatient consultation of angiology, after which the patient is immediately discharged. Although this examination is invasive, non-physiological and expensive, it allows the video recording of the morphology, dynamics and kinetics of the values, of the endovein and of the liquid flows (blood, washing fluid and sclerosing products). The new examination has already enabled us to propose an functional classification of the parietal valves of the great saphenous vein. It makes an intraoperative three-dimensional mapping of the vessels possible, which is sometimes difficult in such particular anatomical regions as the popliteal fossa. It allows performing sclerosis with a visual control and following up the evolution of the immediate endoparietal lesions in situ.
