What is the new term for the "vein of Giacomini"?

The term "vein of Giacomini" has been redefined in modern phlebology as the "cranial extensions vein." This term reflects its anatomical position and the distinct pathway it follows, particularly connecting the great saphenous vein (which is the primary drainage vein of the leg) to the deep venous system. The cranial extensions vein plays an important role in venous drainage from the lower extremities and is considered in various clinical contexts, particularly in the study of chronic venous insufficiency and varicose veins. Understanding this terminology helps improve communication among healthcare professionals regarding venous anatomy and pathology.
