Lymphology and Phlebology are now experiencing a period of profound innovation assisted by continuous technological stimuli, by the progressive improvement of consolidated procedures and by the development of new methods. The two disciplines often run overlapping both from a physiological point of view and from a pathophysiological point of view. The integration between Phlebology and Lymphology is often the starting point for addressing some clinical problems with a different perspective, including the foundations of the two disciplines considering the patient in his entirety and in his relationship with the surrounding environment. The objective of the Web Congress is to underline the importance and clinical relevance of Phlebology and Lymphology, highlighting how they are related to each other, and in some cases the extension of the other, representing the "best practice" for the management of the phlebo-lymphological patient. Timing is also fundamental for a timely diagnosis, an appropriate clinical management of the patient, in a conservative or surgical manner, associated with primary or secondary prevention of possible complications. The two disciplines therefore gravitate around the patient with lymphological and phlebological problems in a harmonious and plenary manner. The heterogeneity of the training and cultural background of the speakers is fundamental for the integration of diagnostic and therapeutic methods in order to complement each other's knowledge.
