The anterior saphenous vein. Part 1. A position statement endorsed by the American Vein and Lymphatic Society, the American Venous Forum, and the International Union of Phlebology

Background: There is a lack of clarity regarding the terminology of the anterior accessory saphenous vein (AASV) that can impact treatment outcomes. Although use of the word “accessory” implies that the vein is a superficial tributary, evidence supports its role as a truncal vein, similar to the great and small saphenous veins, and warranting a change in terminology. Methods: A multisocietal panel was convened by the American Vein and Lymphatic Society (AVLS), the Union International of Phlebology (UIP), and the American Venous Forum (AVF). The group was charged with reviewing the existing anatomic and clinical literature pertaining to the term “anterior accessory saphenous vein” and to consider the need for alternative terminology. Conclusions: Based on the insights gathered from the literature review and extensive discussions, the panel recommends changing the terminology such that the “anterior accessory saphenous vein” (AASV) now be designated the anterior saphenous vein (ASV).
